Catheter ablation in patients with atrial fibrillation and dilated cardiomyopathy

Frontiers in Cardiovascular Medicine

Introduction Catheter ablation is an effective and safe strategy for treating atrial fibrillation patients. Nevertheless, studies on the long-term outcomes of catheter ablation in patients with dilated cardiomyopathy are limited. Among the catheter ablation group, 58.7% ( n  = 27) had persistent atrial fibrillation.

The Role of RyR2 Mutations in Congenital Heart Diseases: Insights Into Cardiac Electrophysiological Mechanisms

Journal of Cardiovascular Electrophysiology

Studies have shown that mutations in the RYR2 gene, which encodes the RyR2 protein, are linked to several cardiac arrhythmias, including catecholaminergic polymorphic ventricular tachycardia (CPVT), long QT syndrome (LQTS), calcium release deficiency syndrome (CRDS), and atrial fibrillation (AF).

Catheter Ablation of Atrial Fibrillation in Infiltrative Cardiomyopathies: A Narrative Review

Journal of Cardiovascular Electrophysiology

Catheter ablation of atrial fibrillation in infiltrative cardiomyopathies ABSTRACT Atrial and ventricular arrhythmias are common in patients with Infiltrative heart diseases. Catheter ablation is a safe and effective modality for the treatment of AF in infiltrative cardiomyopathy.

Bi-atrial arrhythmogenic substrate in patients with hypertrophic obstructive cardiomyopathy

HeartRhythm

Atrial fibrillation (AF) in patients with hypertrophic obstructive cardiomyopathy (HOCM) may be caused by a primary atrial myopathy. Whether HOCM-related atrial myopathy affects mainly electrophysiological properties of the left atrium (LA) or also the right atrium (RA) has never been investigated.

Prognostic Value of Low Voltage Area Burden in Atrial Fibrillation

HeartRhythm

The EHRA/HRS/APHRS/SOLAECE Expert Consensus on Atrial Cardiomyopathies published in 2017 defined atrial cardiomyopathy as “any complex of structural, architectural, contractile, or electrophysiological changes affecting the atria.”1

Assessing the impact of atrial fibrillation on symptoms and quality of life in hypertrophic cardiomyopathy

Journal of Cardiovascular Electrophysiology

Abstract Introduction In hypertrophic cardiomyopathy (HCM), atrial fibrillation (AF) has historically been regarded to have a deleterious impact on clinical course, strongly associated with progressive heart failure (HF) symptoms. Results Among the 218 patients, 50 (23%) had a history of AF and comprise the primary study cohort.

Thromboembolic Complications From Atrial Fibrillation and Atrial Flutter in Pediatrics and Young Adults: A Multicenter Study

Journal of Cardiovascular Electrophysiology

ABSTRACT Background Atrial fibrillation and atrial flutter are relatively rare in young people and the incidence of thromboembolic complications is unknown. Structural heart disease (SHD) was present in 120 patients (57%) and 20 patients (10%) had a primary cardiomyopathy.
