ABSTRACT

As extrassístoles ventriculares (EV) são conhecidas desde o século VII AC, e até o momento existem dúvidas pelos clínicos e mesmo entre grande número de cardiologistas,sobre como abordá-las e consequente terapêutica. Nas últimas décadas surgiram evidências relatadas em trabalhos com grande número de pacientes e em diretrizes devárias sociedades de que as EV em indivíduos sem cardiopatia estrutural, após avaliaçãopor métodos diagnósticos disponíveis, não necessitam de maiores preocupações, já queos riscos de morte se equivalem a uma população normal ou mesmo aos coronarianos com lesões arteriais discretas. Isso equivale a dizer, os assintomáticos não necessitam de nenhum tratamento específico, e se apresentarem sintomas decorrentes da arritmia, apenas terapia com β-bloqueadores e aconselhamento médico. Porém, assintomáticos portadoresde EV com possibilidades de desenvolver quadros clínicos mais severos, devem ter uma abordagem mais criteriosa. Assim, devem submeter-se a avaliação clínica detalhada e talvez emprego de terapia específica, com medicamentos antiarrítmicos e até ablação por cateter, portadores de EV assintomáticos quanto à arritmia, quando esta for frequente– acima de 500 EV por hora – com cardiopatia estrutural, eletrocardiograma com evidênciasde alterações eletrogenéticas, miocardiopatia dilatada e hipertrófica, possibilidade de indução de arritmias ventriculares malignas e fração de ejeção em fase de deterioração...


Premature ventricular contractions (PVC) were first described in the 7th Century BC,but until now, there are doubts among medical professionals, and even among many cardiologists, as to how to address them, or the best conduct for their treatment. In recente decades, evidence has emerged from large clinical trials, and the guidelines of various societies, that PVC in individuals without structural heart disease, after evaluation by the available diagnostic methods, are not a cause for major concern, as the risk of death is equivalent to that of the normal population, or even coronary patients with mild arterial lesions.This means that asymptomatic patients do not require any specific treatment, and if they present symptoms resulting from the arrhythmia, therapy with β-blockers alone, and medical guidance, are advised. However, asymptomatic patients with PVC with the possibility of developing more severe clinical conditions should be more carefully investigated.Patients with asymptomatic PVC in terms of arrhythmia should therefore be submitted to adetailed clinical evaluation, possibly with specific therapy, with antiarrhythmic medications and even catheter ablation, in cases where the arrhythmia is frequent – above 500 PVC per hour – with structural heart disease, electrocardiogram with evidence of electrogenetic alterations, dilated and hypertrophic myocardiopathy, possibility of induction of malignant ventricular arrhythmias, and ejection fraction in the deterioration phase...

ABSTRACT

We report an unknown complication of peripherally inserted central venous catheter in a patient with Ventricular Assist Device. This rare complication led to the failure of the right ventricular assist device, which could be detrimental in patients with dilated cardiomyopathy.

ABSTRACT

La displasia arritmogénica del ventrículo derecho es una afección bien definida con manifestaciones predominantemente arrítmicas. Se analizan los tres casos diagnosticados por nuestro grupo. Estos casos se presentaron como taquicardia ventricular con morfología de bloqueo de rama izquierda, presentando uno de ellos una muerte súbita abortada en la evolución. El electrocardiograma basal y la promediación de señales fueron anormales en dos de los tres casos, al igual que el ecocardiograma. El estudio electrofisiológico logró inducir en los tres pacientes taquicardia ventricular monomorfica sostenida con morfología de bloqueo de rama izquierda. El diagnóstico definitivo se hizo por ventriculografía derecha en dos casos y por resonancia nuclear magnética en el otro. El tratamiento incluyó fármacos antiarrítmicos en los tres casos y la colocación de un cardiodesfibrilador automático en el que sobrevivió a una muerte súbita
