Background The value of empirical superior vena cava isolation (SVCI) following pulmonary vein isolation (PVI) to improve the efficacy of radiofrequency catheter ablation (RFCA) for paroxysmal atrial fibrillation (PAF) remains controversial. RFCA was guided by quantitative AI in both groups. vs 81.5%, p=0.02). 95% CI 0.19

Wild-type transthyretin amyloid cardiomyopathy (ATTRwt-CM) is often accompanied by atrial fibrillation (AF), atrial flutter (AFL), and atrial tachycardia (AT), which are difficult to control because beta-blockers and antiarrhythmic drugs can worsen heart failure (HF).

Abstract Introduction Atrial fibrillation and atrial flutter originating from the donor s heart is a commonly reported complication post heart transplant. Electrophysiologic study demonstrated atrial fibrillation originating from native heart and propagated through atrio-atrial connections to the donor heart.

BACKGROUND:Inflammation may promote atrial fibrillation (AF) recurrence after catheter ablation. This study aimed to evaluate a short-term anti-inflammatory treatment with colchicine following ablation of AF.METHODS:Patients scheduled for ablation were randomized to receive colchicine 0.6 2.02];P=0.89).

Complete and durable block across the left atrial (LA) roof can be integral to ablation of persistent atrial fibrillation (AF) and atypical atrial flutter (AFl). The right pulmonary artery (RPA) is in close proximity to the LA roof, and may provide a vantage for epicardial LA roof mapping and ablation.
