B-PO04-125 IMPACT OF LEFT VENTRICULAR PAPILLARY MUSCLE VENTRICULAR ARRHYTHMIA ABLATION ON MITRAL VALVE FUNCTION

Although efficacious, catheter ablation (CA) of ventricular arrhythmias (VAs) originating from left ventricular (LV) papillary muscles (PAPs) can be challenging and often requires multiple lesions over various aspects of these structures. Such an ablation approach has the potential to adversely impact mitral valve (MV) function. The purpose of this study was to determine if the extent and location of lesions delivered during CA of LV PAP VAs had...
