Abstract:
By using two-dimensional speckle tracking echocardiography, we aimed to investigate the structural and functional changes on myocardium in chronic asymptomatic alcoholics without any cardiovascular disease. Forty-one consecutive asymptomatic male alcoholics who were admitted to the outpatient alcoholism unit and 30 age matched healthy male volunteers selected as the control group were enrolled in the study. The study group were investigated by using standard two-dimensional echocardiography and speckle tracking echocardiography. The left ventricular (LV) global longitudinal strain and LV global circumferential strain were significantly lower in alcoholics when compared with control subjects. There was no difference in global radial strain between the two groups. To demonstrate the effect of total life time dose of ethanol (TLDE) on echocardiographic abnormalities, we assessed the correlation analysis. There was a nonsignificant weak correlation between global LV circumferential strain and TLDE (r=0.27,p=0.083). Speckle tracking echocardiography derived left ventricular systolic function was impaired in chronic alcoholic patients when compared with healthy controls.

Abstract:
Introduction. Left ventricular dysfunction is quite common in septic shock. Speckle-tracking echocardiography (STE) is a novel, highly sensitive method for assessing left ventricular function, capable of detecting subclinical myocardial dysfunction, which is not identified with conventional echocardiography. We sought to evaluate subclinical left ventricular systolic function in patients with septic shock using speckle-tracking echocardiography. Methods. From May 2017 to December 2018, patients aged ≥18 years admitted to the intensive care unit with the diagnosis of sepsis and septic shock based on the sepsis-3 definition were included. Patients with other causes of cardiac dysfunction were excluded. Transthoracic echocardiography was performed for all the patients within 24 hours of diagnosis. Left ventricular systolic function was assessed using conventional echocardiography and speckle-tracking echocardiography. Results. Patients with septic shock (n = 90) (study group) and 37 matched patients with sepsis but no septic shock (control group) were included. Left ventricular ejection fraction (LVEF) by conventional echocardiography showed no significant difference between two groups (58.2 ± 9.9 vs. 58.6 ± 8.3, p=0.804). The global longitudinal strain (GLS) by STE was significantly reduced in patients with septic shock compared with that in the control (−14.6 ± 3.3 vs. −17.1 ± 3.3, p<0.001). Based on the cutoff value of GLS ≥ −15% for the definition of subclinical left ventricular systolic dysfunction, this dysfunction was detected in 50 patients with septic shock (55.6%) and in 6 patients in the control group (16.2%) (p<0.05). Conclusions. Speckle-tracking echocardiography can detect early subclinical left ventricular systolic dysfunction via the left ventricular global longitudinal strain compared with conventional echocardiographic parameters in patients with septic shock.

Abstract:
PDA is one of the most common congenital cardiac malformation in the dog. Echocardiography has been the cornerstone in diagnosing and providing hemodynamic information in a wide variety of disease.Recently, speckle tracking echocardiography has been regarded as a useful tool to assess cardiac function. Aim of the study was to compare cardiovascular hemodynamics in dogs with PDA with healthy control dogs and evaluate any change in cardiac contractility before and after PDA closure. A statistically significant difference was found between standard and advanced echocardiographic techniques, with absolute higher values in dogs with PDA as compared to healthy controls. Cardiovascular hemodynamics were markedly different before and after PDA closure. Based on the results, STE should be considered in echocardiographic assessment of dogs with PDA, as they represent an animal model of congenital left ventricular overload not affected.

Abstract:
Left ventricular (LV) ejection fraction (EF) derived from two-dimensional echocardiography has been the cornerstone for LV function assessment for more than half a century. However, EF is only an indirect measure of cardiac output obtained from changes in LV volume, and does not necessarily reflect intrinsic myocardial contractile properties. Furthermore, LVEF measurement has a number of challenges that relate to image quality, LV geometry assumptions, and technical expertise, and has significant issues with intra-observer, inter-observer, and test-retest variability. A more contemporary marker of LV systolic function is speckle tracking echocardiography (STE)-based global longitudinal strain (GLS). Based on deformation of the cardiac muscle, GLS provides a more direct evaluation of myocardial contractile function. GLS is highly sensitive for the detection of overt LV dysfunction, as well as subclinical LV systolic impairment when LVEF is still considered normal. Furthermore, longitudinal strain has great utility in the evaluation of right ventricular (RV) function, as well as atrial function. Two-dimensional GLS, derived from semiautomatic software, has a high temporal and spatial resolution and consequently, improved inter- and intra-observer reproducibility, compared to LVEF. The overall aim of this thesis was to explore the role of STE-derived GLS in a variety of cardiovascular conditions. Firstly, the utility of GLS in patients with ventricular arrhythmias was assessed, including patients with and without structural heart disease. GLS in cardio-oncology, specifically left-sided breast cancer patients undergoing radiation therapy, was also evaluated. RV strain in patients with pulmonary embolism was studied in order to identify its role in the management of these patients. Finally, left atrial function, including left atrial strain, was addressed in a population of elite athletes with and without atrial fibrillation and compared to non-athletes.

Abstract:
The infiltrative cardiomyopathies are a heterogeneous group of disorders classically characterised by increased wall thickness and progressive diastolic dysfunction. While considered relatively rare, they are likely underdiagnosed, and are increasingly recognized as a significant cause of heart failure with preserved ejection fraction, particularly in the case of amyloidosis. Despite varying markedly in their natural histories and treatments available, they are often difficult to distinguish using conventional echocardiographic techniques. For this reason, novel imaging techniques, and multi-modality imaging are playing an increasing role in the diagnosis, prognostication and monitoring of infiltrative cardiomyopathies. This thesis aims to investigate the role of both conventional and novel echocardiographic techniques in the diagnosis and management of amyloidosis and Fabry disease, two of the more common forms of infiltrative cardiomyopathy.

Abstract:
Die technologische Entwicklung im Bereich der Echokardiographie hat in der letzten Dekade neue Methoden zur objektiven Erfassung der regionalen linksventrikulären Wandbewegung ermöglicht. Speckle Tracking erfasst die myokardiale Deformation durch die Positionsänderung einzelner Bildpunkte von einem Bild des analysierten Datensatzes zum nächsten. Diese Methode ist dem Gewebedoppler überlegen, insbesondere wegen ihrer Unabhängigkeit vom Anlotungswinkel. Zwei-dimensionale (2D) Speckle Tracking Analysen wurden für die klinische Praxis validiert. Die drei-dimensionale (3D) Echokardiographie erlaubt inzwischen Speckle Tracking Analysen von 3D Datensätzen, welche jedoch für die klinische Praxis noch nicht ausreichend validiert sind. Bei Patienten mit normaler regionaler linksventrikulärer Wandbewegung (N=37), sowie bei Patienten mit ischämie-bedingten Wandbewegungsstörungen (N=18) wurden 3D und 2D Speckle Tracking Analysen durchgeführt. Die Vergleichbarkeit der beiden Methoden hinschtlich der Quantifizierung von normalen und pathologischen Wandbewegungsmustern wurde anhand dieser Messungen geprüft. Des weiteren wurde der Einfluss der Bildrate und Bildqualität drei-dimensionaler Datensätze auf die Vergleichbarkeit beider Methoden analysiert. Es zeigte sich eine gute Vergleichbarkeit des 2D und 3D Speckle Tracking in der Diagnostik eingeschränkter linksventrikulärer systolischer Funktion, sowie in der Lokalisationsdiagnostik umschriebener Wandbewegungsstörungen. 2D und 3D Speckle Tracking sind jedoch noch nicht als gleichwertige Methoden anzusehen. Die Bildqualität, generell bei beiden Modalitäten - jedoch speziell bei 3D Datensätzen, sowie die Bildrate der 3D Datensätze zeigen signifikante Einflüsse auf die 3D Strain Analysen. Eine korrekte Standardisierung der analysierten Aufnahmen und eine optimale Bildqualität sind wichtige Faktoren, die die Zuverlässigkeit des 2D und 3D Speckle Trackings bestimmen.

Abstract:
Background: Critical care echocardiography has become standard of care in the ICU. New technologies have been developed and have shown potential clinical utility to elucidate myocardial dysfunction not seen with conventional imaging. We sought to determine the feasibility and potential clinical benefit of these techniques in common situations seen in the ICU. Hypothesis: Advanced echo techniques would be feasible in the majority of critically ill patients and have prognostic significance, clinical utility and diagnose cardiac abnormalities, potentially in a more sensitive manner than conventional techniques. Results: (a) Speckle tracking echocardiography (STE) Left ventricle and RV analysis with STE was feasibly in ~80% of patients. More dysfunction was found using STE vs conventional analysis. RV dysfunction assessed by STE held significant prognostic relevance in those with septic shock and highlighted subtle dysfunction induced by mechanical ventilation, both in animal and human studies. (b) 3D transthoracic echocardiography (3D TTE) Despite finding 3D TTE feasible in mechanically ventilated ICU patients (LV 72% and RV 55%), it lacked necessary low variability and high precision vs standard measures. (c) Myocardial contrast perfusion echocardiography (MCPE) Assessing acute coronary artery occlusion in the ICU patient is challenging. Troponin elevation, acute ECG changes, regional wall motion analysis on echo and overall clinical acumen often lack diagnostic capabilities. MCPE was found to be feasible in the critically ill and had better association predicting acute coronary artery occlusion vs clinical acumen alone. Conclusions: STE, 3D TTE and MCPE are feasible in the majority of ICU patients. STE may show dysfunction not recognised by conventional imaging. 3D TTE for volumetric analysis is likely not suitable for clinical use at this stage. MCPE may help guide interventions in acute coronary artery occlusion.

Abstract:
L’analyse de la fonction systolique en échocardiographie représente un challenge majeur depuis une vingtaine d’années dans le but d’améliorer la détection et la quantification des anomalies de la contraction myocardique. L’analyse des déformations myocardiques consiste à étudier le pourcentage d’étirement ou de raccourcissement myocardiques au cours du cycle cardiaque. Après le grand pas en avant dans ce domaine, consécutif à l’avènement du Doppler tissulaire il y a un quinzaine d’années, ces 4 dernières années ont vu naître une nouvelle technique d’analyse bidimensionnelle des déformations, porteuse de grands espoirs car s’affranchissant de la limitation liée à l’angle d’incidence Doppler et basée sur le suivi des marqueurs acoustiques de la paroi myocardique : le « speckle tracking echocardiography » ou « 2D strain ». Cette thèse rapporte tout d’abord une série de travaux orientés sur la validation de ce nouvel outil. Nous avons ensuite appliqué expérimentalement cette technique pour évaluer sa capacité à détecter l’ischémie myocardique lors d’un examen de stress sous dobutamine en comparaison à l’analyse de perfusion myocardique en échographie de contraste. Enfin, nous exposons plusieurs expériences cliniques qui témoignent de quelques applications potentielles de cette technique dans la prise en charge des patients porteurs de cardiopathies diverses : myocardiopathie hypertrophique, fibrillation auriculaire paroxystique et recherche de viabilité sous faibles doses de dobutamine chez les patients porteurs d’une cardiopathie ischémique
For 20 years, analysis of systolic myocardial function by echocardiography is a major challenge to improve the detection and the quantification of myocardial contractility abnormalities. The principle of myocardial deformation analysis consists in evaluating the percentage of myocardial thickening or shortening during the cardiac cycle. After a big step forward with the advent of tissue Doppler imaging for 15 years, the 4 last years have seen the apparition of a new technique of bidimensional analysis, without angle dependency, based on the tracking of the acoustic markers of the myocardial wall, and called « speckle tracking echocardiography » or « 2D strain ». This thesis reports serial studies oriented on the validation of this new tool and on the experimental application of this technique in the detection of myocardial ischemia during pharmacological dobutamine stress echocardiography, in comparison with myocardial perfusion analysis by contrast echocardiography. Finally, we report some clinical experiences using the speckle tracking echocardiography which attest of some clinical potential applications of this technique in the management of the patients with different cardiomyopathies: hypertrophic cardiomyopathy, lone paroxysmal atrial fibrillation, and analysis of myocardial regional deformation during low doses dobutamine infusion to investigate viability in patients with ischemic cardiomyopathy

Abstract:
Haemodialysis patients represent an extreme phenotype of cardiovascular risk with a pattern of disease distinct from that in the general population. Non-traditional risk factors, specific to chronic kidney disease such as hypervolaemia, arterial stiffness and advanced glycation end-product deposition are increasingly recognised. A previously demonstrated non-traditional risk factor associated with worse outcomes is the presence of uraemic cardiomyopathy. This pattern of cardiac morphology and function has previously been defined as the presence of left ventricular abnormalities, including left ventricular hypertrophy, dilatation and left ventricular systolic dysfunction. For the first time the work in this thesis studies an incident haemodialysis population using multi-parametric strain-based imaging. This uses the accuracy of cardiovascular magnetic resonance imaging of resting cardiac and aortic morphology and function augmented with strain by tagging to longitudinal strain changes during haemodialysis by speckle-tracking echocardiography. The general aim of this thesis was to characterise the relationship of left ventricular function to haemodialysis using strain-based imaging. This might allow characterisation of haemodialysis-associated cardiomyopathy which may be distinct from the traditional definition of uraemic cardiomyopathy and may better define those patients who would benefit from modifications to the process of haemodialysis.

Resumo: O objetivo do presente estudo foi investigar a função miocárdica pela técnica de ecocardiografia bidimensional speckle tracking (2D STE) em pacientes submetidos à procedimentos anestésico prolongado, com a intenção de se detectar possível disfunção sistólica. Inicialmente para se determinar o intervalo normal da função sistólica na espécie, foram utilizados 31 coelhos da raça Nova Zelândia, adultos, hígidos, machos, com peso médio de 4,0 ± 0,53 kg, nos quais foram obtidos os índices sistólicos radiais como, velocidade rotacional e radial, deslocamento rotacional e radial, strain radial e strain rate radial. Posteriormente, para investigação da função sistólica sob diferentes modalidades ventilatórias, 32 coelhos foram distribuídos, aleatoriamente, em quatro grupos de modalidades ventilatórias diferentes constituídos de 8 animais cada, denominados grupo ventilação ciclada à pressão (GP), grupo ventilação ciclada à pressão associada à PEEP (GPP), grupo ventilação mandatória intermitente sincronizada (GM) e grupo ventilação espontânea (GE). Em todos os grupos, os parâmetros foram mensurados 40 minutos após a indução anestésica (M0) e reavaliados a cada vinte minutos, durante duas horas ininterruptas (M1, M2, M3 e M4). Portanto, o resultado demonstrados na presente investigação cientifica revelam que nenhuma modalidade ventilatória estudada proporcionou um quadro de disfunção sistólica a luz da técnica 2D STE quando foram comparados em cada momento de avaliação anestésica.

Initially, the normal range of left ventricular radial systolic function was measured, for this purpose, 31 healthy male adults New Zealand rabbits were used, with average weight of 4.0 ± 0.53 kg, from a specialized producer; radial systolic indices were obtained, such as rotational and radial speed, rotational and radial displacement, radial strain and strain rate. Subsequently, 32 rabbits were randomly assigned to four groups of different ventilatory modalities consisting of 8 animals each, referred to as pressure-cycling ventilation group (GP), pressure-cycling ventilatory group associated with PEEP (GPP), synchronized intermittent mandatory ventilation group (GM) and spontaneous ventilation group (GE). In all groups, the parameters were measured 40 minutes after anesthetic induction (M0) and reevaluated every twenty minutes, for two uninterrupted hours (M1, M2, M3 and M4).

A cardiomiopatia arritmogênica do ventrículo direito (CAVD) é uma doença de origem genética, muito prevalente em cães da raça Boxer. Histologicamente ocorre atrofia dos cardiomiócitos do ventrículo direito (VD) e consequente infiltração fibroadiposa, levando ao aparecimento de arritmias ventriculares. Mesmo sendo as alterações miocárdicas microscópicas em sua maioria, estudos recentes têm identificado disfunção contrátil do ventrículo direito, mesmo em estágios iniciais da doença em humanos, tanto por técnicas convencionais de ecocardiografia quanto por técnicas mais avançadas, como no caso do speckle tracking. Por isso, o objetivo deste estudo foi avaliar se há disfunção miocárdica de VD detectável pela ecocardiografia convencional e pela técnica de speckle tracking bidimensional em cães da raça Boxer portadores da CAVD. Para tanto, utilizou-se cães da raça Boxer com idade superior a quatro anos, distribuídos em dois grupos de acordo com o resultado da avaliação Holter (GC: < 50 EVs/24h, n=11 e GD: > 100 EVs/24h, n=11). Os animais foram submetidos a ecocardiografia e avaliou-se diâmetro e comprimento interno do VD em sístole e diástole, encurtamento fracional da área do VD (FAC), excursão sistólica do plano anular da tricúspide (TAPSE), velocidade miocárdica sistólica do ânulo lateral da tricúspide derivada do Doppler tecidual (S’) e deformação (strain) e taxa de deformação (strain rate) longitudinal global da parede livre do VD, derivados da análise por speckle tracking. As variáveis foram comparadas entre os grupos pelo teste t de Student e de Mann-Whitney e a correlação entre variáveis ecocardiográficas convencionais e de speckle tracking e o número e severidade das arritmias pelo teste de correlação de Pearson, com nível de significância de 5%. Os grupos não foram estatisticamente diferentes e não houve correlação entre os dados. Os resultados da pesquisa demonstraram que a ecocardiografia, tanto na avaliação do VD por índices sistólicos convencionais quanto por aqueles derivados da técnica de speckle tracking não foram capazes de detectar disfunção miocárdica do VD em Boxers portadores de CAVD.
Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a genetic disease with a high prevalence in Boxer dogs. Histologically, right ventricle (RV) cardiomyocytes’ atrophy occurs, and thus fibrofatty infiltration, triggering ventricular arrhythmias. Although the myocardial changes are mostly microscopic, recent studies in human beings have identified right ventricular systolic dysfunction even in the early stages of ARVC, both by conventional echocardiographic techniques and advanced methods, such as speckle tracking. Therefore, the aim of this study was to investigate if RV myocardial dysfunction is present in Boxers affected by ARVC, evaluated by conventional echocardiography and bidimensional speckle tracking technique. For this purpose, Boxers older than four years were recruited, and based on 24-hour Holter recording were divided in groups: GC:< 50 VPC/24h (n=11), or GD: > 100 VPC/24h (n=11). The following echocardiographic parameters were analyzed: RV internal dimension during systole and diastole; RV fractional area change (FAC); tricuspid annular plane systolic excursion (TAPSE); myocardial systolic velocity of lateral tricuspid annulus (S’), and global longitudinal strain and strain rate. Groups were compared by Student’ t-test or Mann-Whitney test according distribution, and correlation between conventional and speckle tracking echocardiographic variables, as well as number and severity of the ventricular arrhythmias were accomplished by the Pearson test, assuming a level of significance at 5%. Groups were considered similar, and there was no correlation among the evaluated parameters. Our findings suggesting that the echocardiographic evaluation of RV, either by conventional and speckle tracking techniques, were not able to detect systolic myocardial dysfunction in Boxers affected by ARVC.

Abstract:
Echocardiographic strain imaging, also known as deformation imaging, has been developed as a means to objectively quantify regional and global myocardial function. First introduced as a post-processing feature of tissue Doppler imaging velocity converted to strain and strain rate, strain imaging has more recently also been derived from speckle tracking analysis. Tissue Doppler imaging yields velocity information from which strain and strain rate are mathematically derived whereas two-dimensional speckle tracking yields strain information from which strain rate and velocity data are derived. Data obtained from these two different techniques may not be equivalent due to limitations inherent with each technique. Speckle tracking analysis can generate longitudinal, circumferential, and radial strain measurements and left ventricular twist. Although potentially useful, these measurements are also complicated and frequently displayed as difficult-to-interpret waveforms. Strain imaging is now considered a robust research tool and has great potential to play many roles in routine clinical practice. This chapter explains the fundamental concepts of deformation imaging, the technical features of strain imaging using tissue Doppler imaging and speckle tracking, and the strengths and weaknesses of these methods.

Abstract:
Echocardiography plays a pivotal role in the management of patients with dilative cardiomyopathy and conduction disease, particularly in the setting of cardiac resynchronization therapy (CRT). Current CRT guidelines recommend the echocardiographic assessment of left ventricular size and function. Furthermore, echocardiography has the potential of analysing regional myocardial mechanics with high temporal resolution and without radiation burden or danger for the patient. Assessment of left ventricular dyssynchrony has therefore become the next challenge. Besides the visual approaches, newer methods of functional imaging such as tissue Doppler and speckle tracking allow the exact quantification of regional myocardial function. This chapter reviews the current status of left ventricular dyssynchrony assessment by echocardiography and introduces emerging techniques which can better link conduction abnormalities and mechanical events and, thus, potentially improve clinical decision-making in this field.

Abstract:
Echocardiography is an excellent tool for the diagnosis and follow-up of patients with cardiomyopathies, myocarditis, and the transplanted heart. It is the preferred method for assessment of ventricular function and valvular dysfunction and is of great value in decision-making in these patients. The different types of cardiomyopathies can usually be differentiated by echocardiography. Speckle tracking echocardiography has increased our awareness on early staging of the disease and the progress of cardiomyopathies. This chapter will explain important features of the most common cardiomyopathies and how echocardiography should be utilized. Echocardiographic findings in myocarditis include non-specific features such as decreased left ventricular function, wall motion abnormalities, and texture changes. These findings will in certain circumstances often prompt the awareness of myocarditis. Echocardiography has an important diagnostic position in patients with end-stage heart failure. The chapter will explain how echocardiography can be used in the screening period of recipients and donors, and how it can be an essential diagnostic tool in the perioperative and postoperative phases of cardiac transplantation.

Abstract:
Assessing the right ventricle by any imaging modality is a challenge because of the thin wall and crescent shape that wraps around the left ventricle. Structured echocardiographic examination using two-dimensional imaging provides a detailed regional and global qualitative assessment for routine evaluation. Quantitation is possible using one or more methods including tricuspid annulus plane systolic excursion, fractional area change, and myocardial performance index but speckle tracking deformation imaging and three-dimensional echocardiography are emerging as more robust quantitative methods. Right ventricular pressures should also be estimated routinely as long as a clear tricuspid regurgitant jet is identified.

Abstract:
Echocardiography is the cornerstone examination for the assessment of aortic regurgitation (AR): it provides reliable evaluation of the aortic valve and allows diagnosis and identification of the mechanism of regurgitation. The specific aetiology of the disease can be identified in the majority of cases. A combination of quantitative and quantitative Doppler and two-dimensional (2D) echocardiographic parameters allows the evaluation of the severity of AR and determination of the haemodynamic and left ventricular function repercussions. Echocardiography allows the detection of associated lesions of the aortic root or other valves. In symptomatic patients, echocardiography is essential to confirm the severity of AR. In asymptomatic patients with moderate or severe AR, echocardiography is essential for regular follow-up, by providing precise and reproducible measurements of LV dimensions and function, and for identifying patients who should be considered for elective surgical intervention. In most cases, transthoracic echocardiography (TTE) provides all of the necessary information and transoesophageal echocardiography in usually not required. Real-time three-dimensional (3D) TTE can be complementary to 2D echocardiography for the assessment of the mechanism and quantification of AR by increasing the level of confidence, especially when 2D echocardiographic data are inconclusive or discordant with clinical findings. Tissue Doppler imaging and especially the speckle tracking method are promising approaches to detect early LV dysfunction in patients with asymptomatic severe AR. Echocardiography is therefore the key examination for the assessment of AR and at the centre of the strategic discussion concerning the indications and timing of surgery.

Abstract:
Right ventricular (RV) performance plays an important role in the morbidity and mortality of patients with left ventricular dysfunction, congenital heart disease, and pulmonary hypertension. Assessment of RV size, function, and haemodynamics has been challenging because of its complex geometry. Conventional two-dimensional echocardiography is the modality of choice for assessment of RV function in clinical practice. Recent developments in echocardiography have provided several new techniques for assessment of RV dimensions and function, include tissue Doppler imaging, speckle-tracking imaging, and volumetric three-dimensional imaging. However, specific training, expensive dedicated equipment, and extensive clinical validation are still required. Doppler methods interrogating tricuspid inflow and pulmonary artery flow velocities, which are influenced by changes in pre- and afterload conditions, may not provide robust prognostic information for clinical decision-making. This chapter addresses the role of the various echocardiographic modalities used to assess the RV and pulmonary circulation. Special emphasis has been placed on technical considerations, limitations, and pitfalls of image acquisition and analysis.
