Delayed ruptured sinus of Valsalva: A rare late complication of common idiopathic PVC/VT ablation

Outflow tract premature ventricular contractions (PVCs) represent a common form of idiopathic ventricular arrhythmia typically observed in patients with structurally normal hearts. Although frequently presenting as palpitations or shortness of breath, a high-burden of PVCs or non-sustained ventricular tachycardia (NSVT) can lead to tachycardia-induced cardiomyopathy and progressive hemodynamic deterioration if left untreated. Because medical therapy often yields a poor response, radiofrequency catheter ablation has emerged as a key therapeutic approach.
