Catheter Ablation of Premature Ventricular Contractions Originating from Kissing Papillary Muscles

Academic Article

Abstract

  • A 73-year-old woman with premature ventricular contractions (PVCs) had very thick left ventricular papillary muscles (PAMs) kissing each other. The PVC origin at the septal side of the anterolateral PAM that faced the posteromedial PAM, rendered mapping confusing. This case illustrated an unusual challenge in catheter ablation of PAM PVCs.
