Objective. To describe the quality of life in patients with idiopathic ventricular arrhythmias treated at the Instituto Nacional Cardiovascular INCOR in Lima -Peru. Materials and methods. Analytical and cross-sectional study of patients with idiopathic ventricular arrhythmias treated by 3D ablation or antiarrhythmic therapy between July 2017 and December 2019 to whom the SF-36 health questionnaire was applied to assess quality of life related to health. Results. Fifty-two patients with idiopathic ventricular arrhythmias were included (34 underwent 3D ablation, and 18 underwent antiarrhythmic therapy only). The percentage of recurrence (14.7% vs. 50%, p=0.01) and adverse effects (0% vs. 22.2%, p=0.011) were lower in the 3D ablation group compared to the antiarrhythmic group. The mean standardized scores obtained from the Spanish version of the Health Survey SF-36v2, applied to the 3D abla...

Interatrial septal occlusion devices hinder the transseptal approach for atrial fibrillation ablation,making it necessary to have imaging methods that safely guide transseptal puncture, such as intracardiac echocardiography (ICE). We describe the case of a 49-year-old patient with symptomatic paroxysmal atrial fibrillation, refractory to antiarrhythmic drugs, wearing an interatrial septal occlusion device, with a previous unsuccessful ablation attempt. Atrial fibrillation ablation was performed using the Carto V7 3D mapping system,  the transseptal puncture was guided by ICE, and the procedure was successful. This case report highlights the importance of multimodality imaging to achieve successful and effective transseptal puncture for atrial fibrillation ablation in patients with interatrial septal occlusion devices.

Los dispositivos de oclusión del septo interatrial dificultan el abordaje transeptal para la ablación de la fibrilación auricular, por lo que es necesario contar con métodos de imagen que guíen con seguridad la punción transeptal, como la ecocardiografía intracardíaca (EIC). Se describe el caso de un paciente de 49 años con fibrilación auricular paroxística sintomática, refractaria a fármacos antiarrítmicos, portador de un dispositivo de oclusión del septo interatrial, con intento previo de ablación fallido. La ablación de la fibrilación auricular se realizó con el sistema de mapeo 3D Carto V7, la punción transeptal fue guiada por EIC y el procedimiento fue exitoso. Este reporte de caso resalta la importancia de la multimodalidad en imágenes, con el fin de se logre una punción transeptal exitosa y eficaz para llevar a cabo la ablación de fibrilación auricular en p...

Cardiac amyloidosis (CA) is a form of cardiomyopathy characterized by the extracellular deposit of protein fibers in the myocardium, leading to the development of heart failure, arrhythmias, and electrical conduction system alterations. It is known that most cardiomyopathies have a close relationship with heart rhythm abnormalities, however, CA is specially related to different kinds of arrhythmias even in pre-diagnosis stages. Arrhythmias like atrial fibrillation are present in up to 70% of patients with CA associated with a high risk of cardioembolic complications independent of the risk stratification. Ventricular arrhythmias are frequent, but the use of implantable cardioverter defibrillator has not been demonstrated to improve survival. The Atrial-Ventricular node disease is also common, and is frequently associated with the implantation of a pacemaker, even in asymptomatic patients...

La amiloidosis cardíaca (AC) es una forma de cardiomiopatía caracterizada por el depósito extracelular de fibrillas de proteínas en el miocardio, lo que produce insuficiencia cardíaca, arritmias y alteraciones en el sistema de conducción eléctrica. La mayoría de las cardiomiopatías tienen una estrecha relación con las alteraciones del ritmo cardiaco, en especial la AC que está asociada a diferentes formas de arritmias, incluso en fases previas al diagnóstico. Arritmias como la fibrilación auricular se observan hasta en el 70% de los pacientes con AC asociadas a un especial riesgo de complicaciones cardioembólicas independiente de la estratificación de riesgo. Las arritmias ventriculares son frecuentes; sin embargo, la colocación del cardiodesfibrilador implantable no ha demostrado mejorar la sobrevida. La enfermedad del sistema de conducción eléctrica también es común...

The risk of sudden death in hypertrophic cardiomyopathy is related to the presence of ventricular arrhythmias in most cases. Finding the best schemes to assess the probability of arrhythmic complications will remain a challenge for modern Cardiology. Meanwhile, the multifactorial approach is the best strategy to avoid the unnecessary implantation of devices such as the implantable cardioverter defibrillator. Although the electrocardiogram remains an excellent diagnostic tool, even before echocardiographic expression, it does not have a clear role as a risk factor. However, the identification of associated arrhythmias such as preexcitation or long QT and variants of presentation as apical hypertrophic cardiomyopathy, allows identifying patients with high probability of sudden death. During the last few years, cardiac resonance and quantification of intramyocardial fibrosis (the basic mech...
