Full textAbstract:
Coronary artery anomalies are seen in less than 1% of the general population and in 1.6% of cardiac catheterization cases. The anomalous origin of the coronary artery from the pulmonary artery is one of four groups of coronary artery origin anomalies. The incidence of anomalous origin of the right coronary artery from the pulmonary artery is 1 in 500,000 and was first described in 1882 by John Brook. This case report reports on a 67-year-old man with a diagnosis of asymptomatic anomalous origin of the right coronary artery from the pulmonary artery. The patient underwent surgery of the aortic valve because of valve stenosis. A concomitant surgical procedure included repositioning of the right coronary artery origin to the aortic root sinus. The patient was discharged on the 12th postoperative day, in good condition. Anomalous origin of the right coronary artery from the pulmonary artery is commonly asymptomatic, and surgery is required only if myocardial ischemia is presented.

AbstractObjectivesTo describe our experience in the management of coronary artery anomalies both in an adult and in a paediatric population and to compare the two groups for finding out differences in terms of angiographic incidence and treatment.Patients and methodsDatabases at the Department of Cardiology of San Martino Adult's Hospital and of Gaslini Children's Hospital were searched for all patients with a diagnosis of coronary artery anomaly who underwent coronary angiography between 1994 and 2006.ResultsCoronary anomalies were diagnosed in 76 (1%) adult patients. Anomalous left circumflex artery was the commonest coronary anomaly (25%). Anomalous left coronary artery from pulmonary artery and myocardial bridges were the only anomalies responsible for angina-like symptoms. No patients except the one with anomalous left coronary artery from pulmonary artery needed surgical intervention. In the paediatric population, we found 28 (0.9%) patients with coronary anomalies. Anomalous left coronary artery from pulmonary artery was the most common anomaly (48%) and always required emergency surgical treatment; in addition there were two patients with stenosis of the left main coronary artery.ConclusionCoronary artery anomalies may be associated with very acute, even life-threatening symptoms in children, whereas they are usually clinically silent and detected by accident on coronary angiography in adults. Recognition of coronary artery anomalies enables early treatment or close follow-up in children, whereas it could be useful in case of cardiac surgery in adults.

Anomalies of the coronary artery are uncommon, with a reported incidence of 0.3% to 1.3% in the coronary angiography studies routinely performed for suspected atherosclerotic coronary disease. There were 0.92% incidence of anomalous origination of the right coronary artery from the left sinus and the 0.15% incidence of anomalous origination of the left coronary artery from the right sinus. Most coronary artery anomalies are diagnosed by invasive angiography performed to investigate suspected atherosclerotic coronary disease. There are two important managements for patient with anomaly coronary artery. First, these coronary anomalies should result in exclusion from participation in intense competitive sports to reduce the risk of a cardiac event or sudden death. Second, and more importantly, treatment for wrong sinus coronary artery anomalies are revascularization can be either surgical or percutaneous. Surgical intervention should be considered for high-risk varieties of anomalous coronary arteries, as this is the only treatment that has been demonstrated to improve coronary blood flow and carries a low morbidity and mortality.

Sudden cardiac arrest has been reported to occur in patients with congenital anomalous coronary artery disease. About 80% of the anomalies are benign and incidental findings at the time of catheterization. We present a case of sudden cardiac arrest caused by anomalous left anterior descending artery. 61-year-old African American female was brought to the emergency department after sudden cardiac arrest. Initial EKG showed sinus rhythm with RBBB and LAFB with nonspecific ST-T wave changes. Coronary angiogram revealed no atherosclerotic disease. The left coronary artery was found to originate from the right coronary cusp. Cardiac CAT scan revealed similar findings with interarterial and intramural course. Patient received one-vessel arterial bypass graft to her anomalous coronary vessel along with a defibrillator for secondary prevention. Sudden cardiac arrest secondary to congenital anomalous coronary artery disease is characterized by insufficient coronary flow by the anomalous left coronary artery to meet elevated left ventricular (LV) myocardial demand. High risk defects include those involved with the proximal coronary artery or coursing of the anomalous artery between the aorta and pulmonary trunk. Per guidelines, our patient received one vessel bypass graft to her anomalous vessel. It is important for clinicians to recognize such presentations of anomalous coronary artery.

Full textAbstract:
We experienced two cases with anomalous origin of the left anterior descending artery (LAD) from the proximal right coronary artery requiring coronary artery bypass grafting. A 66-yr old female with a long history of angina and a positive stress test had the anomalous artery coursing anterior to the right ventricular outflow tract. A 42-yr old male with worsening angina after an anteroseptal myocardial infarction had the anomalous artery running between the great vessels. Both patients underwent left internal mammary artery-to-LAD bypass on the beating heart with complete resolution of ischemic symptoms. Isolated coronary artery anomaly is an uncommon disease (0.6–1.2%) in patients undergoing cardiac catheterization [1, 2]. An anomalous origin of the LAD from the proximal right coronary artery (RCA) or the right sinus of Valsalva (RSV) is very rare, found in 1.2–6.1% of all coronary anomalies [1, 2]. This coronary anomaly has been considered potentially serious but functionally unimportant [2]. We report two cases of anomalous LAD from the proximal RCA resulting in anterior wall ischemia which was effectively treated by coronary artery bypass surgery.

Abstract During dissection conducted in an anatomy department of the right upper limb of the cadaver of a 70-year-old male, both origin and course of the radial and ulnar arteries were found to be anomalous. After descending 5.5 cm from the lower border of the teres major, the brachial artery anomalously bifurcated into a radial artery medially and an ulnar artery laterally. In the arm, the ulnar artery lay lateral to the median nerve. It followed a normal course in the forearm. The radial artery was medial to the median nerve in the arm and then, at the level of the medial epicondyle, it crossed from the medial to the lateral side of the forearm, superficial to the flexor muscles. The course of the radial artery was superficial and tortuous throughout the arm and forearm. The variations of radial and ulnar arteries described above were associated with anomalous formation and course of the median nerve in the arm. Knowledge of neurovascular anomalies are important for vascular surgeons and radiologists.

Full textAbstract:
In the Syrian hamster, anomalies in the origin of the left coronary artery are significantly associated with the bicuspid condition of the aortic valve. In this species, bicuspid aortic valves are expressions of a trait, the variation of which takes the form of a phenotypic continuum, ranging from a tricuspid aortic valve with no commissural fusion to a bicuspid aortic valve with the aortic sinuses located in ventrodorsal orientation and devoid of any raphe. The intermediate stages of the continuum are represented by tricuspid aortic valves with a more or less extensive fusion of the ventral commissure and bicuspid aortic valves with a more or less developed raphe located in the ventral aortic sinus. The present study was designed to decide whether there is a gap between tricuspid and bicuspid aortic valves regarding the incidence of coronary artery anomalies, or whether this incidence varies according to the different tricuspid and bicuspid morpho types of the continuum. The study was carried out in Syrian hamsters belonging to a single inbred family with a high incidence of tricuspid aortic valves with fusion of the ventral commissure, bicuspid aortic valves, and anomalies in the origin of the left coronary artery, i.e. single right coronary artery ostium in aorta, anomalous origin of the left coronary artery from the pulmonary artery, and anomalous origin of the left coronary artery from the dorsal aortic sinus. The specimens were examined by means of a stereomicroscope and, in several cases; scanning electron microscopy was also used. The relationships between anomalous coronary artery patterns and aortic valve morphologies were tested using a logistic regression model. The results obtained indicate that there is no discontinuity between tricuspid and bicuspid aortic valves regarding the incidence of coronary artery anomalies. The probability of occurrence of anomalous coronary artery patterns increases continuously according to the deviation degree of the aortic valve from its normal (tricuspid) design. The present findings suggest that in the Syrian hamster, the morphogenetic mechanisms involved in the formation of congenital anomalous aortic valves and anomalies in the origin of the left coronary artery, respectively, are strongly related from an aetiological viewpoint.

Introduction:Congenital anomalous coronary artery is a rare condition, but it might be the biggest pitfall for cardiologist. It might be silent until the patient reach young adult and has high intensity activity. Symptomatic anomalous course of coronary artery has wide spectrum from asymptomatic until the lethal one.Case Ilustration: We present a case of young adult with activity-triggered atypical chest pain and diagnose with anomalous origin of right coronary artery (RCA) from the left coronary sinus with inter-arterial course between the aorta and the main pulmonary artery that was detected by CT coronary angiography. This anomaly has been called malignant course RCA.Discussion:Coronary artery anomaly is a congenital condition. Most of the cases are remain asymptomatic. This condition also one of the most cause for sudden cardiac death because the coronary artery examination is not regularly done. Nevertheless, during high intense activity, it will be symptomatic and might be lethal.Conclusion:Diagnose coronary artery anomalies might be tricky and cardiologist must be aware with this. More devastating, no firm guideline in treatment of right anomalous coronary artery from opposite sinus.

Anomalous origin of left main coronary artery or right coronary artery from the aorta with subsequent coursing between the aorta and pulmonary trunk is rare and can be sometimes life threatening. After hypertrophic cardiomyopathy, coronary artery anomalies are the second most common cause of sudden cardiac deaths among young athletes. This is a case presentation of an anomalous origin of right coronary artery from left main coronary artery coursing between the pulmonary trunk and aorta. Patient presented with STEMI and had coronary bypass surgery.

Full textAbstract:
Thesis (M.A.)--Boston University<br>The anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital heart defect occurring approximately one out of every 300,000 live births. ALCAPA is a coronary artery anomaly in which the left coronary artery originates anomalously from the pulmonary trunk rather than from its usual origin, the aorta. It is a serious heart defect with a presentation range from severe congestive heart failure and left ventricular dysfunction in infants to asymptomatic survival into adulthood. ALCAPA is one of the most common causes of myocardial ischemia and infarction in infants and children, and if untreated can cause death in up to 90% of cases due to heart failure.
With technological advances in diagnosis and treatment, there are increasing numbers of ALCAPA patients surviving into adulthood. This trend is seen with CHD in general with over 85% of treated children born with CHD surviving into adulthood today with an estimated increase in the next few decades. Although ALCAPA patients undergo "corrective" surgery, they are never truly cured, and patients must manage their condition as a mild, moderate, or potentially severe chronic disease. Through a review of current literature about ALCAPA patients and adults with CHD in general, this thesis explores the postoperative physiological outcome, psychosocial effects, and health care options of treated pediatric ALCAPA patients that survived into adulthood.
We have found that there are still significant unknowns about the future of adult ALCAPA survivors. First, earlier diagnosis and treatment of ALCAPA can lead to good outcomes, yet it is unknown whether it is feasible to find the defect before it manifests and treat it before any damage has occurred. Secondly, long-term studies of patients are currently insufficient to determine the health of these patients past a decade or two. Lastly, the current health care options for ALCAPA and adults with CHD in general do not currently meet the needs of this unique population, as they require highly specialized services in order to ensure their health.

Full textAbstract:
L’angioscanner des artères coronaires est utilisé de façon croissante chez l’enfant dans le diagnostic, le suivi, et les bilans pré- et post-chirurgicaux des pathologies à risque d’atteinte coronaire, et plus particulièrement dans certaines cardiopathies congénitales. Son utilisation en pédiatrie reste cependant limitée par la présence d’artefacts de mouvements cardiaques, dégradant la qualité d’image et entravant potentiellement le diagnostic, ainsi que par le caractère irradiant de l’examen, et le risque de cancer radio-induit associé à prendre en considération dans cette population pédiatrique.L’objectif de ce travail de thèse a été d’évaluer et de proposer des stratégies d’amélioration de l’angioscanner des artères coronaires réalisé chez l’enfant atteint de cardiopathie congénitale.Cinquante enfants âgés de moins de 18 ans, d’une cohorte de patients présentant une cardiopathie congénitale impliquant la réalisation d’un angioscanner des artères coronaires, ont été prospectivement inclus dans le protocole de recherche clinique COROPEDIA (Observational study for feasibility and performance of sub-millisievert coronary computed tomography angiography for coronary artery anomalies in paediatric patients), mis en place au cours de cette thèse. Entre 2017 et 2018, ces enfants ont ainsi bénéficié d’un angioscanner des artères coronaires, réalisé sur un scanner mono-source à large collimation.La première partie de ce travail a consisté en l’élaboration d’un protocole d’acquisition optimisé, dérivé des dernières études réalisées chez l’adulte (très peu de publications chez l’enfant). Quinze scenarii d’acquisitions spécifiques ont ainsi été mis en place en fonction du rythme cardiaque du patient et de sa variabilité. Ces acquisitions multiphasiques sélectives ont permis de répondre à la question clinique posée dans 100% des cas, pour une dose efficace équivalente à moins de 4 mois d’irradiation naturelle.Afin d’améliorer d’avantage la qualité de visualisation des structures tout en réduisant les durées d’irradiation, deux autres études ont été menées. Ainsi, l’impact d’algorithmes de correction d’artefacts de mouvements a été évalué en pédiatrie. Une interprétabilité équivalente aux reconstructions multiphasiques a été obtenue dans une unique phase cardiaque reconstruite par le logiciel, alors que les reconstructions monophasiques traditionnelles montraient une interprétabilité significativement inférieure. Ces solutions logicielles permettraient donc d’améliorer la visualisation des structures cardiaques, tout en réduisant encore les durées d’acquisitions scanographiques nécessaires au diagnostic et donc les doses délivrées aux enfants.Enfin, dans un troisième temps, les artefacts cinétiques de chacun des 50 patients ont été quantifiés dans 7 phases cardiaques différentes. Cette évaluation portant sur un total de 5733 structures cardiaques, a permis de définir les positions (70%, 80%, 40%, 47%, 50%, 54% de l’intervalle R-R, respectivement) et durées optimales (10%, 20%, 50%, 50%, 20%, 10% du cycle cardiaque, respectivement) des fenêtres d’acquisition, en fonction du rythme cardiaque de l’enfant (≤60 bpm, 61-75 bpm, 76-85 bpm ; 86-100 bpm ; 101-130 bpm ; >130 bpm).La mise en application simultanée de ces stratégies d’optimisation, devraient permettre la réalisation d’angioscanner des artères coronaires de qualité diagnostique chez n’importe quel enfant, pour une dose d’irradiation inférieure à 0,5 mSv, soit moins de 2 mois d’exposition naturelle<br>Coronary computed tomography angiography (CCTA) has been increasingly used in pediatrics for diagnosis, follow-up, and pre or post-surgery assessment of coronary artery anomalies, and more generally in congenital heart diseases. However, its use remains limited by cardiac motion artifacts, potentially resulting in non-diagnostic acquisitions, and by children’s exposure associated with a risk of radiation induced cancers.The aim of this thesis was to evaluate and optimize CCTA performed in children with congenital heart disease.Fifty children (<18 years old), with congenital heart disease requiring coronary artery imaging were prospectively enrolled in the COROPEDIA clinical trial, specifically designed during the thesis (Observational study for feasibility and performance of sub-millisievert coronary computed tomography angiography for coronary artery anomalies in paediatric patients). Between 2017 and 2018, these children underwent a coronary CT angiography, performed on a wide-coverage, single-source CT. The first part of this work was dedicated to elaborating an optimized acquisition protocol, derived from adult studies (very few studies have been conducted with pediatric patients). Fifteen acquisition schemes were designed to deliver irradiation at the best theoretical moment, as a function of patient’s heart rate and variability. These selective multiphasic acquisitions fully answered the clinical question for every child, delivering a radiation dose equivalent to less than 4 months of natural background irradiation.Two additional studies were conducted to improve cardiac structure visualization while reducing further children’s exposure.The impact of motion correction algorithms in children undergoing CCTA was investigated. The results suggested that multiple phases provided significantly better interpretability than traditional single-phase acquisitions. However, the second motion correction algorithm generation offered similar interpretability in a single retrospectively processed cardiac phase and could be adopted to improve coronary artery visualization while reducing beam-on-time and children’s exposure to radiation.Finally, motion artifacts of every fifty patients were quantified in seven different cardiac phases. On a total of 5733 cardiac structures evaluated, optimal positions (70%, 80%, 40%, 47%, 50%, 54% of the R-R interval, respectively) and durations (10%, 20%, 50%, 50%, 20%, 10% of the cardiac cycle, respectively) of the acquisition window were defined as a function of children’s heart rates (≤60 bpm, 61-75 bpm, 76-85 bpm ; 86-100 bpm ; 101-130 bpm ; >130 bpm).These optimization strategies might be simultaneously implemented to achieve CCTA of diagnostic quality in any children, for less than 0.5 mSv, or two month of natural background irradiation

Based on this substantial comparative study, we have proposed a new classification approach of seven ST-T anomaly classes, by using a hybrid of the boosting and the random under sampling methods, our goal was ultimately to reach the best tradeoff between true-positives and false-positives

Johannesburg, 27 January 2016<br>Objective: To describe the demographics, nutritional status, clinical features and assess the outcomes of patients diagnosed with AOPA (anomalous origin of the pulmonary artery from the aorta) in a developing country.
Methods: Retrospective cross-sectional review of all children and adults with AOPA seen between April 1990 and April 2015 at the Chris Hani Baragwanath Academic Hospital, a tertiary care institution. All available clinical, radiographic, electrocardiographic, echocardiographic, computed tomography scan, cardiac catheterization and angiography, operative and follow-up data was reviewed from the case files and database.
Results: Seventeen patients (infants, n = 15) were diagnosed with AOPA and ten (59%) were male. The median age was 81 days (2 days-36 years). Two thirds (77%,10/13) of the patients were malnourished and 46% (6/13) had severe malnutrition. The most common presentation was congestive cardiac failure and severe pulmonary hypertension was present in all the patients.The diagnosis was made on echocardiography in ten patients (59%) and on catheterization angiography in six patients (35%). Fourteen patients (82%) had anomalous origin of the right pulmonary artery (AORPA). The most common associated cardiac defect was patent ductus arteriosus (PDA). Surgery was undertaken in three patients and three patients were deemed inoperable. The overall mortality was 82% (14/17).
Conclusion: High morbidity and mortality is associated with AOPA if early diagnosis and surgery is not achieved. Mortality is related to early development of pulmonary hypertension and progressive congestive cardiac failure. Late presentation and lack of adequate resources may be contributing factors to the mortality in a developing country.<br>MT2017

Full textAbstract:
碩士<br>國立陽明大學<br>生物醫學影像暨放射科學系暨研究所<br>100<br>Coronary artery anomalies (CAA) can be benign or malignant, the later may result in coronary artery disease, myocardial ischemia and sudden death. Different classifications of CAA have been reported since 1990. Most of the previous classifications of CAA have been based on invasive cardiac catheterization. The purpose of this study is to assess the clinical relevance classification of coronary artery anomalies detected with 64 multi-slice computed tomography (64-MSCT).
A total of 1,974 subjects (1,351 male, mean ages of 50.5±10.9) who underwent 64-MDCT from June 2006 to June 2009 were identified retrospectively. All of the CT images were reviewed for coronary artery variants and anomalies. All data were interpreted by a radiologist and a cardiologist. The coronary artery anomalies were classified as four groups: benign, relevant, severe and critical, based on the clinical relevance proposed by Rigatelli et al. in 2003. Subjects with coronary artery anomalies (except myocardial bridging) were analyzed for their clinical syndromes. The average follow-up time is 31.3±12 months. Three scan protocols were used for these patients: ECG tube current modulation (ETCM) with 70-80% exposure window, 40-80% exposure window and retrospective ECG-gating. Among them, the radiation dose and exposure saving were compared.
The incidence of anomal anatomical origin and course of the coronary arteries in our study was 3.19 % (n = 63), benign 37, relevant 13, severe 10 and critical 3. Ten subjects were excluded due to lack of follow-up information, including 3 benign, 6 relevant and 2 severe patients. We analyzed the relationship between the classification of CAA and subjects’ symtoms during follow-up. None of the clinical symtoms had significant statistical differences among the 4 groups (P&lt;0.05). Subjects using ECG tube current modulation (ETCM) with 70-80% exposure window can lower radiation and save dose (P&lt;0.001).
MSCT is superior to the conventional angiography for diagnosing CAA due to its convenience, non-invasiveness, and three-dimensional capability. It can be the first imaging modality to diagnose CAA in early stage. Early detection of CAA can be useful for managing patients with percutaneous intervention or surgical procedure. Although no significant difference in the outcome among the 4 groups was found in this study, the severe and critical CAA patients can still benefit from the acknowledgement of CAA and prevent extreme exercise to avoid sudden death.

Trabalho Final do Mestrado Integrado em Medicina apresentado à Faculdade de Medicina<br>Introdução: A artéria umbilical única (AUU) é uma malformação diagnosticada ecograficamente no período pré-natal e está relacionada com um maior risco de anomalias congénitas. No presente estudo, caracterizou-se uma população de grávidas diagnosticadas com AUU, para compreender a sua associação, quando isolada (AUUi), a desfechos obstétricos e perinatais adversos assim como, à necessidade de uma vigilância ecográfica e aconselhamento pré-natal personalizados. Métodos: Foi realizada uma análise retrospetiva observacional e descritiva de 160 mulheres grávidas, diagnosticados com AUU, entre o ano de 2007 e 2019, no setor de ecografia e diagnóstico pré-natal de um Hospital terciário. Foram obtidos registos de características maternas, achados perinatais e desfechos obstétricos, posteriormente estudados e analisados através do software Microsoft Office Excel.Resultados: Das mulheres grávidas estudadas, 32,5% tinham idade avançada, 16,3% hábitos tabágicos, 9,2% Diabetes Mellitus gestacional e 5,1% recorreram a técnicas de procriação medicamente assistida. Registou-se uma AUUi em 65% dos casos, estando associada a anomalias congénitas nos restantes. Em 33,8% dos fetos detetou-se alguma malformação estrutural, estando mais afetados o sistema músculo-esquelético (22%), génito-urinário (20%) e cardiovascular (19%). 11,3 % dos fetos foram diagnosticados com cromossomopatias, havendo apenas 1,3% sem malformações estruturais. A restrição do crescimento fetal (RCF)/baixo peso ao nascimento observou-se em 9,4% dos fetos com AUUi. Foram registados 3,1% nados-mortos, 13,8% partos pré-termo e houve 38,2% partos por cesariana. Discussão: Na maioria dos casos, a AUU foi um achado isolado, não se encontrando associada a outras malformações. No entanto, em cerca de um terço dos casos encontrou-se associada a malformações estruturais, sobretudo dos sistemas músculo-esquelético, génito-urinário e cardiovascular, justificando-se uma avaliação ecográfica fetal atenta nestes sistemas, com eventual recurso a ecocardiografia fetal. Como a maioria dos fetos com cromossomopatias contaram com malformações estruturais, o estudo genético deve ser oferecido quando alguma anomalia estrutural é detetada. Nos casos de AUUi, a maior incidência de RCF/baixo peso ao nascimento salienta a necessidade de uma avaliação ecográfica apertada do crescimento fetal. A AUU parece associar-se a outros desfechos adversos, incluindo a prematuridade, a morte fetal e o parto por cesariana, revelando a importância de uma vigilância e aconselhamento pré-natal personalizados. Conclusão: Perante o diagnóstico de AUU deve ser realizada uma avaliação ecográfica detalhada e equacionado o estudo genético, caso seja detetada alguma malformação estrutural. Na ausência de malformações, a associação entre AUU e desfechos perinatais adversos suportam a recomendação de uma vigilância ecográfica pré-natal personalizada, particularmente do crescimento fetal.<br>Background: Single umbilical artery (SUA) is a malformation diagnosed by prenatal ultrasound and is associated with other congenital abnormalities. In the present study, a population of pregnant women diagnosed with SUA was characterized to understand its association, when isolated (iSUA), with adverse obstetric and perinatal outcomes, as well as the need of personalized ultrasound surveillance and prenatal counseling. Methods: Observational and descriptive retrospective analysis of 160 pregnant women, diagnosed with SUA, between 2007 and 2019, in the ultrasound and prenatal diagnosis unit of a tertiary Hospital. Data on maternal characteristics, fetal findings and obstetric outcomes were recorded, and were studied and analyzed using Microsoft Office Excel software.Results: Of the pregnant women studied, 32,5% had advanced age, 16,3% had smoking habits, 9,2% had gestational Diabetes Mellitus and 5,1% conceived by assisted reproductive technologies. SUA was an isolated finding in 65% of cases and was associated with some congenital anomaly in 35%. 33,6% fetuses showed at least one structural malformation. Musculoskeletal (22%), genitourinary (20%) and cardiovascular (19%) were the systems more involved. 11,3% fetuses were diagnosed with chromosomal abnormalities and only 1,3% had no associated structural malformations. Intrauterine fetal growth restriction (IUGR)/low birth weight was present in 9,4% fetuses with iSUA. There were 3,1% stillbirths, 13,8% preterm delivery, and 38,2% cesarean delivery. Discussion: In most cases, SUA was an isolated finding and was not associated with other malformations. However, about one third of the cases were found to be associated with structural malformations, affecting mainly the musculoskeletal, genitourinary and cardiovascular systems, justifying a watchful fetal ultrasound assessment, with the possible use of fetal echocardiography. Since most fetuses with chromosomal abnormalities had structural malformations, the genetic study must be offered when any structural anomaly is detected. The higher incidence of IUGR/low birth weight in iSUA highlights the need for a close ultrasound assessment of fetal growth. SUA appears to be associated with other adverse outcomes, including prematurity, fetal death and caesarean delivery, revealing the importance of personalized prenatal surveillance and counseling. Conclusion: Towards the presence of a single umbilical artery, a detailed ultrasound evaluation of the fetus should be performed, and genetic testing must be considered, if any structural malformation is detected. In the absence of malformations, the association between SUA and adverse perinatal outcomes supports the recommendation for personalized prenatal ultrasound surveillance, especially fetal growth assessment.

Full textAbstract:
Coronary anomalies occur in less than 1% of the general population and their clinical presentation can range anywhere from a benign incidental finding to the cause of sudden cardiac death. Since congenital coronary arteries anomalies are often considered as the first cause of cardiac death in young athletes in Europe, careful attention has to be paid in this specific subpopulation in case of suggestive symptoms. Although focused expert echocardiography is the first-line imaging tool, coronary computed tomography or radiation-free magnetic resonance imaging are recommended for more definitive definition of the coronary course in persons suspected of having coronary artery anomalies. Most coronary anomalies belong to the group of anomalous origin. Aneurysms are defined as dilations of a coronary vessel 1.5 times the normal adjacent coronary artery segment. Coronary artery fistulas are communications between one or more coronary arteries and a cardiac chamber (coronary-cameral), the pulmonary artery, or a venous structure (such as the sinus or superior vena cava).

Full textAbstract:
Coronary artery anomalies occur either in isolation or in the context of congenital heart defects (CHD). Isolated coronary artery anomalies include anomalies of connection to the pulmonary artery or to the aorta, anomalies of the intrinsic coronary arterial anatomy including anomalous orifices, and anomalies of myocardial/coronary arterial interaction including myocardial bridges and fistulae. Such defects are of major significance in clinical cardiology and cardiac surgery because of their association with myocardial ischaemia and sudden death. Coronary anomalies associated with CHD can result from three types of developmental perturbation: (1) anomalous epicardial course (in congenitally corrected transposition of the great arteries and L-looped ventricles), (2) anomalous communication with a high-pressure ventricular cavity (pulmonary atresia with intact ventricular septum and hypoplastic left heart syndrome), or (3) anomalous connection to the aorta. Outflow tract defects represents 30–40% of CHD, and their main characteristic is great artery defects influencing coronary arterial anatomy.

O Departamento de Edificações e de Rodovias do Espírito Santo (DER-ES), a fim de levantar a atual situação de todas as Obras de Arte Especiais (OAE) existentes na malha rodoviária sob sua administração, realizou a contratação de serviços técnicos especializados de pesquisa, cadastro, inspeção cadastral e avaliação de todas as pontes com base na ABNT NBR 9452 (2019), DNIT 010 PRO (2004) e no Manual de Inspeções de Pontes Rodoviárias – DNIT. As inspeções que estão sendo realizadas consistem na verificação visual das características geométricas e estruturais, das manifestações patológicas e das anomalias nas estruturas e em seus elementos. A partir dos resultados está sendo elaborado um plano de manutenção e reabilitação das estruturas. Até o momento, 722 pontes já foram inspecionadas por todo o estado, indicando desde estruturas em excelentes condições até obras com riscos iminentes de colapso. A maior parte das OAE vistoriadas foram classificadas com condição de estabilidade boa e aparentemente boa, sendo observado que as estruturas com notas inferiores, classificadas como precárias e sofríveis, estão concentradas na região Sul do estado. Ações urgentes foram planejadas e estão sendo executadas para os casos mais graves. Para as estruturas com danos mais brandos estão sendo elaboradas planilhas, que objetivam a contratação de serviços de manutenção e conservação. O DER-ES visa manter um monitoramento regular das pontes sob sua responsabilidade, via inspeções regulares a fim de garantir a segurança e a funcionalidade interrupta da malha rodoviária estadual.

Full textAbstract:
Coronary arteries are located on the surface of the heart and supply oxygenated blood to the myocardium and other components of the heart. The two coronary arteries located above the aortic arch are the Left Coronary Artery (LCA) and Right Coronary Artery (RCA). The LCA branches into the Left Anterior Descending (LAD) and the Left Circumflex (LCx) while the RCA branches into the Right Marginal Artery (RMA) and Post Descending Artery (PDA). The coronary arteries are likened to a complex tube-like structure, and the motion of the heart cause changes in pressure, which allows proper blood circulation during the systolic and diastolic phases [1]. Since it is essential to understand the physiological and hemodynamical behavior of the heart and coronary arteries, numerous studies have been conducted at different artery locations in the heart. Most of the research has focused on the branches between the LAD and LCx, with little or no attention directed towards the take-off angle the LCA makes with the aortic root. Although it has been reported that certain take-off angles of left main (LM) can be considered anomalous, findings have documented that such take off angles can make the artery prone to atherosclerosis and sudanophilia diseases [2]. Computational Fluid Dynamics (CFD) has in recent years been used to solve a wide variety of fluid flow challenges, and can be used for this study. The goal of this study is to use CFD techniques to study the hemodynamics of the different take-off angles of the left coronary artery from the aortic root. This will help identify areas in the left coronary artery that could be prone to atherosclerosis buildup.
