Heart failure (HF), a complex clinical syndrome arising from structural or functional cardiac impairment, carries substantial morbidity with 30% early readmission rates within three months post-discharge and strong mortality associations [(1)](#ref-0001). The pathophysiological interplay between atrial fibrillation (AF) and HF presents particular clinical challenges, as their concomitant presence portends worse prognoses than either condition in isolation[(2)](#ref-0002) . Moreover, biventricular dyssynchrony emerges as a critical pathophysiological determinant of impaired ventricular filling and reduced cardiac output [(3)](#ref-0003). The tripartite convergence of these conditions creates a high-risk clinical scenario requiring sophisticated therapeutic strategies. We present a novel management approach for a patient with HF complicated by persistent AF and biventricular dyssynchrony. Our therapeutic paradigm employed sequential interventions: initial atrioventricular node ablation (AVNA) with biventricular cardiac resynchronization therapy (BiV-CRT) implantation, followed by delayed AF radiofrequency ablation 18 months later[(4)](#ref-0004). This staged strategy successfully restored both atrioventricular and interventricular synchronization. Notably, the patient maintained clinical stability without HF-related rehospitalization throughout the follow-up period.
