TL;DR
A surgical method using cryoablation successfully treats heart rhythm issues in the left ventricular summit when other methods fail.
Contribution
A novel surgical approach for treating refractory PVCs using cryoablation during aortic valve replacement.
Findings
Cryoablation effectively eliminated PVCs in the LV summit.
The procedure was guided by preoperative activation mapping.
No epicardial access was required during the procedure.
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.
