Atrial fibrillation ablation in heart failure patients: improved systolic function after cryoballoon pulmonary vein isolation.

ABSTRACT:

Aims

Atrial fibrillation (AF) and heart failure (HF) are the most common cardiac diseases and often coexist leading to increased mortality and morbidity compared with AF patients without HF. As shown previously, AF ablation using radio frequency (RF) in HF patients leads to a reduction of AF burden, an increase of left ventricular ejection fraction (LVEF) and consequently to reduced hospitalization and mortality. Previous AF ablation studies on HF patients have been liberal about additional targets beyond pulmonary vein isolation (PVI). Thus, the aim of this study was to assess systematically the impact of a straightforward PVI-only strategy on LVEF, NYHA functional class, and cardiovascular hospitalization rate in HF patients.
