Surgical cryoprobe ablation for premature ventricular contraction of left ventricular summit refractory to catheter ablation

Abstract

The successful elimination of left ventricular (LV) summit premature ventricular contractions (PVCs) using surgical endocardial cryoablation. Guided by preoperative activation mapping, cryoablation was performed during aortic valve replacement without epicardial access. This approach effectively resolved PVCs refractory to catheter ablation.
