B-AB22-01 UTILITY OF PROLONGED DURATION ENDOCARDIAL ABLATION FOR SUCCESSFULLY TARGETING CHALLENGING VENTRICULAR ARRHYTHMIAS ORIGINATING FROM THE LEFT VENTRICULAR SUMMIT REGION

Catheter ablation (CA) of ventricular arrhythmias (VAs) originating from the left ventricular summit (LVS) region can be challenging. Different mapping and ablation strategies have been utilized to target these VAs. We sought to explore whether prolonged duration (PD) radiofrequency ablation (RFA) from adjacent endocardial locations can improve CA outcomes of LVS VAs. Patients undergoing CA of LVS VAs from 01/2016-12/2019 were included. Standard...
