Abstract

A 29 year-old male was noted with symptomatic high burden premature ventricular contractions (PVC) despite therapy with betablockers. An electrophysiology study was done. Activation map and pacemapping localized the PVC to the tip of the papillary muscle. Ablation of papillary muscle PVCs is often challenging because of the anatomical variability, potentially deep intramural site of arrhythmia origin, and the stability issues related to the ablation of a mobile target.
