La prevención de eventos cardioembólicos isquémicos es probablemente, el objetivo principal en el manejo dealgunas patologías en cardiología. De ahí que el uso de anticoagulantes es familiar para los cardiólogos (y cirujanos cardiovasculares), sobretodo desde el uso de prótesis valvulares quirúrgicas.

BACKGROUND: In 2015, the Ministry of Health (MINSA) of Peru inaugurated the first national center for electrophysiology studies in a public tertiary referral hospital with the purpose to provide healthcare access to the most underserved population. This study aims to describe the rate of success and complications of catheter ablation in this center since its inception, as well as the demographic characteristics of these patients. METHODS: This study is descriptive and retrospective. We used the medical record of the patients who underwent catheter ablation (first-time and re-do procedure) in the center from July 2015 to February 2018. RESULTS: 55 catheter ablations were performed in 53 patients, who were 35 (±15) years old and 47% male. 63.6% had a full MINSA health coverage, while 16.4% and 20% had partial MINSA coverage and no health coverage, respectively. Atrio-ventricular reentrant...

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...
