Full textArrythmogenic Right Ventricular Dysplasia/Cardiomyopathy (ARVD/C) is a myocardial illness whose etiology is still unknown, which affects mostly the right ventricle and is histologically characterized by the replacement of myocytes by fibrous and adipose tissue. Clinically it appears mainly in young adults with episodes of arrhytmias, tachycardia, syncope and/or sudden death which usually occur related to physical exercise. According to the described series, the prevalence is widely varied, probably reflecting the geographic distribution of this pathology. The patients diagnosed with ARVD are candidates to an active therapeutic approach, which includes invasive electro physiological procedures and the placement of Implantable Cardioverter-Defribrillators (ICD). Patients who suffer frequent arrhythmic storms, with energetic break downs of ICD and some cases that envolve to severe congestive heart failure, may be candidates to cardiac transplant. In the described clinical case the patient not only presents multiple characteristics but also ARVD compatible symptomatology.

Full textHistorically, left ventricular cardiomyopathy and coronary heart disease have been regarded as the main causes of ventricular arrhythmia and sudden cardiac death. However, within the last two decades, arrhythmias originating from the right ventricular have begun to attract the attention of the scientific world for many reasons. Ventricular arrhythmias originating from the right ventricular usually affect younger patients and can lead to sudden cardiac death. The pathophysiologic mechanism of these arrhythmias is not fully understood, which can lead to a range of different interpretations. Arrhythmogenic cardiomyopathy corresponds to a hereditary disease of the cardiac muscle, where the myocardium is replaced by fibro-fatty tissue and is characterized clinically by potentially lethal ventricular arrhythmias, especially in young individuals and athletes. Although the right ventricle is affected more frequently, biventricular or left dominant involvement has also been described. Considering the "disease of the desmosomes", several mutations have been reported in genes coding for desmosomal proteins, leading to intracellular changes in signal transduction and, consequently, myocyte transformation. The clinical diagnosis is based on a system that combines genetic and familial factors, electrocardiographic variations, ventricular arrhythmias, histopathological findings and functional or structural variants of the right ventricle, pertinent in the recognition of the nonspecific characteristics of this entity. Affected individuals present mostly during the second or third decades of life with symptoms such as palpitations, syncope or cardiorespiratory arrest. However, the presence of asymptomatic carriers has also been reported in favor of trend genetic sequencing. The primary goal of treatment is to prevent sudden death events. Given its increasing clinical relevance and significant scientific impact, this dissertation considers the broad review of the pathogenesis, diagnosis and current therapy related to this rare form of cardiomyopathy.

Full textA cardiomiopatia/displasia arritmogénica do ventrículo direito é uma miocardiopatia hereditária que pode resultar em arritmias, falência e morte súbita cardíaca. Foram publicadas, no início da nova década, novas recomendações para o diagnóstico desta doença. Porém, dado que estes apresentam ainda algumas limitações e o conhecimento na área tem avançado progressivamente, decidimos avaliar quais os contributos recentes que poderão ajudar o aperfeiçoamento das mesmas. Foi feita uma pesquisa eletrónica na MEDLINE (via PubMed) usando as palavras-chave: “displasia arritmogénica ventrículo direito” e “arrhythmogenic right ventricular dysplasia”entre Janeiro de 2009 e Maio de 2012 tendo sido obtidas 254 resultados. Após a avaliação dos sumários foram selecionados 27 artigos para a realização da revisão sistemática. De uma análise dos artigos selecionados depreende-se que os testes genéticos são importantes ferramentas diagnósticas, porém os exames auxiliares de diagnóstico de imagem e a monitorização eletrocardiográfica continuam a desempenhar um papel charneira no estudo e abordagem diagnóstica destes doentes
Arrhythmogenic right ventricular dysplasia/cardiomyopathy is a heritable cardiomyopathy that can result in arrhythmia, heart failure and sudden cardiac death. In the beginning of this decade new recommendations for the diagnosis of this pathology have been published. However, as these recommendations still present some limitations and there is a constantly growing knowledge-base, we decided to evaluate recent contributes that can help in their improvement. An electronic search was performed in the MEDLINE (via PubMed) using the keywords “displasia arritmogénica ventrículo direito” and “arrhythmogenic right ventricular dysplasia” between January 2009 and May 2012 obtaining 254 result. After evaluating the abstracts we selected 27 articles for this systematic review. From the analysis of the selected articles we inferred that genetic testing represents is an important diagnostic tool. However, imaging exams and electrocardiographic monitoring still have an important role and are the mainstay in the diagnostic approach and assessment of these patients

Full textA Displasia Arritmogénica Ventricular Direita (DAVD) é uma cardiomiopatia primária rara que apresenta uma incidência de 1 em 2000 até 1 em 5000 indivíduos na população em geral. No entanto, é considerada uma importante causa de morte súbita em jovens e especialmente em atletas. A DAVD é, geralmente, uma doença hereditária, com padrão de transmissão autossómico dominante, caracterizada histologicamente pela substituição de tecido do miocárdio por tecido adiposo e fibroso no ventrículo direito, podendo existir envolvimento do ventrículo esquerdo numa fase mais tardia da doença. Estudos reportam que mutações nos genes que codificam para proteínas desmossomais conseguem justificar a doença em cerca de 50 % dos pacientes com DAVD. O teste genético é útil na confirmação do diagnóstico clínico, particularmente nos indivíduos que não preencham todos os critérios propostos para a doença, e ainda na adopção de medidas preventivas nos membros da família dos pacientes afectados. Neste trabalho foi proposta a optimização, para cada gene responsável pela DAVD, da amplificação das regiões de interesse individualmente, através de reacções de PCR simples e, posteriormente amplificar, na mesma reacção, vários exões simultaneamente utilizando a PCR multiplex. Uma vez que não existem quaisquer registos publicados sobre o estudo molecular da DAVD em Portugal, pretendeu-se neste trabalho fazer o rastreio molecular dos genes PKP2, DSP e DSG2, numa amostra de 40 pacientes portugueses com suspeita clínica de DAVD, que desde 2007 deram entrada no IPATIMUP. O rastreio molecular foi efectuado recorrendo à sequenciação directa de todos os exões e regiões intrónicas flanqueantes dos genes em estudo. A optimização das reacções de PCR multiplex reduziu em mais de 80 % o número de reacções a efectuar para cada caso em análise. Na prática implica aproximadamente 1/5 dos gastos em reagentes ao nível da amplificação do DNA, mas também uma significativa redução no tempo de preparação das reacções. Foram identificadas 11 mutações em heterozigotia em 9 pacientes (9/40). Desta forma pode-se dizer que 22,5 % dos pacientes com suspeita clínica amostrados são portadores de mutações nos principais genes associados à doença, e que por isso, o diagnóstico genético permite confirmar a suspeita clínica da doença. O gene PKP2 foi o mais frequentemente mutado entre os pacientes presentes na amostra (90,9 %), com 10 mutações identificadas, seguindo-se o gene DSG2 (9,1 %) com uma mutação. Três das mutações em PKP2 não tinham sido anteriormente descritas. Em nenhum dos pacientes foram identificadas mutações no gene DSP.
Arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) is a primary cardiomyopathy that presents an incidence from 1 in 2000 to 1 in 5000 individuals in the general population. However, ARVD/C is an important cause of sudden death in the young and especially in athletes. ARVD/C is a most inherited disease, generally presenting an autosomal dominant pattern of transmission, histologically characterized by fibrofatty replacement of the right ventricular myocardium, and the possible involvement of the left ventricle and the septum in late stages. Several studies report that mutations in genes coding for desmosomal proteins may prove the disease in 50 % of the patients with ARVD/C. Genetic testing is useful to confirm the clinical diagnosis, particularly in individuals who do not completely fulfil Task Force criteria for the disease, thereby also enabling the adoption of preventive measures in family members. In this work it was proposed the optimization, of target regions amplification for each gene related to the disease, using simple PCR, and later the amplification, of several exons simultaneously in the same reaction, using PCR multiplex. Since there are no published data about ARVD/C molecular studies in Portugal, this study also pretends to make a molecular screening of the 3 most important desmosomal genes related with ARVD/C: PKP2, DSP and DSG2, in a sample of 40 Portuguese patients with clinical suspicion of ARVC/D, that since 2007 entered in IPATIMUP. Mutation screening was performed by direct sequencing technique of all exons and flanking intronic regions of the target genes. The optimization of multiplex PCR reactions reduced the total number of reactions in more than 80%. Implying in practice 1/5 of the costs of reagents related with amplification, but also a significant reduction in the time to prepare the reactions. Eleven heterozygous mutations were detected in 9 patients (9/40). Consequently, 22.5 % of the patients with clinical suspicious of ARVD/C presented mutations in the 3 most important desmosomal genes related with ARVD/Cand therefore, the molecular diagnostic may confirm the clinical suspicion of the disease in these cases. The most frequently mutated gene was PKP2 (90.9 %), with 10 mutations found, followed by DSG2 (9.1 %) with just 1 screened mutation. Three of the 10 detected mutations in PKP2 gene were novel. The screened patients didn’t present any mutations in DSP gene.
