Tachycardia-induced cardiomyopathy reversal and spontaneous closure of iatrogenic atrial septal defect following AF ablation: A case report

Abstract

Atrial fibrillation (AF) is associated with significant morbidity and mortality, particularly due to its relationship with left ventricular dysfunction. This case report describes a 73-year-old female patient with AF and heart failure with reduced ejection fraction, who demonstrated significant left ventricular function recovery following cryoballoon ablation. This case report also underscores the vital role of catheter ablation in managing AF-induced heart failure (HF) and illustrates the benign course of small iatrogenic atrial septal defects post-procedure. By recognizing tachycardia-induced cardiomyopathy, clinicians can prioritize appropriate interventions for patients with new-onset HF and AF, leading to substantial improvements in cardiac function and overall outcomes.
