Catheter ablation of atrial fibrillation in patients with systolic left ventricular dysfunction

Atrial fibrillation (AF) is the most common arrhythmia among the adult population, affecting up to 2% of the population. Among patients with chronic heart failure (CHF), the prevalence of AF reaches 12.3%. The presence of common risk factors and pathophysiological mechanisms of AF and CHF development lead to the frequent combination of these two pathologies, which has a negative impact on the course of the underlying disease and further prognosis, increasing the chances of adverse outcomes such as stroke, myocardial infarction, and cardiovascular mortality. The results of most randomized studies indicate that interventional treatment of AF in patients with CHF and intermediate to low left ventricular ejection fraction (LV) contributes to reducing the functional class of CHF and improving quality of life, but at the same time, there is currently no consensus on the effectiveness, safety, and extent of catheter intervention. In this review, we attempted to summarize the literature data regarding the outcomes of interventional treatment of AF in patients with systolic LV dysfunction.
