Amiodarone or implantable cardioverter-defibrillator in chagas cardiomyopathy: the CHAGASICS randomized clinical trial

IMPORTANCE: Over 10 000 people with Chagas disease experience sudden cardiac death (SCD) annually, mostly caused by ventricular fibrillation. Amiodarone hydrochloride and the implantable cardioverter-defibrillator (ICD) have been empirically used to prevent SCD in patients with chronic Chagas cardiomyopa...

Seguimento dos pacientes com síndrome arritmogênica do prolapso valvar mitral após implante de cardioversor desfibrilador implantável
Follow-up of patients with arrhythmogenic mitral valve prolapse syndrome after implantable cardioverter defibrillator implantation

Int. j. cardiovasc. sci. (Impr.); 37 (suppl.9), 2024
INTRODUÇÃO: A síndrome arritmogênica do prolapso valvar mitral (PVM) é uma condição associada a eventos arrítmicos ventriculares e morte súbita cardíaca (MSC). O acompanhamento por telemetria do cardioversor-desfibrilador implantável (CDI) pode aprimorar a compreensão dessa síndrome por ser ...

Epicardial substrate ablation in high-risk brugada syndrome patients: systematic review and single-arm meta-analysis

Int. j. cardiovasc. sci. (Impr.); 37 (suppl.9), 2024
INTRODUCTION: Brugada syndrome (BrS) is a genetic heart disease that predisposes individuals to malignant ventricular arrhythmias and sudden cardiac death (SCD). Although implantable cardioverter-defibrillators (ICDs) and quinidine are primary treatments, recurrent BrS-triggered cardiac ventricular arrhy...

Intrinsecoid deflection as a risk predictor for sudden cardiac death in hypertrophic cardiomyopathy

Arq. bras. cardiol; 119 (5 supl.1), 2022
INTRODUCTION: Sudden Cardiac Death (SCD) and Malignant Ventricular Arrhythmias (MVA) in patients with Hypertrophic Cardiomyopathy (HCM) occurs in up to 0.9%/ year. Identifying risk predictors for such an event is of paramount importance, considering the indication of Implantable Cardiodefibrillator (ICD)...

Relationship between ventricular repolarization parameters and the inducibility of ventricular arrhythmias during electrophysiological study in patients with coronary artery disease

OBJECTIVE: Risk stratification of sudden cardiac death in patients with coronary artery disease is of great importance. We evaluated the association between ventricular repolarization and induction of malignant ventricular arrhythmias on electrophysiological study of patients with coronary artery disease...

Preditores de arritmia ventricular maligna em pacientes com miocardiopatia hipertrófica e cardiodesfibrilador implantável
Predictors of malignant ventricular arrhythmia in patients with hypertrophic cardiomyopathy and implantable cardioverter defibrillator

Arq. bras. cardiol; 117 (6 supl.1), 2021
INTRODUÇÃO: A morte súbita cardíaca é uma das complicações mais temidas em portadores de Miocardiopatia Hipertrófica (MCH) e geralmente decorre de eventos arrítmicos ventriculares. Acomete principalmente jovens e atletas e pode ser a primeira manifestação clínica da doença, justificando a im...

Association of variants in MYH7, MYBPC3 and TNNT2 with sudden cardiac death-related risk factors in Brazilian patients with hypertrophic cardiomyopathy

Hypertrophic cardiomyopathy (HCM) is characterized by unexplained left ventricular hypertrophy (LVH) and is one of the major causes of sudden cardiac death (SCD). An exon-targeted gene sequencing strategy was used to investigate the association of functional variants in sarcomeric genes (MYBPC3, MYH7 and...

Current role of cardiac magnetic resonance imaging in hypertrophic cardiomyopathy
