Case of idiopathic left ventricular summit premature ventricular contractions successfully treated by catheter ablation

Catheter ablation (CA) of premature ventricular contractions (PVCs) arising from the left ventricular summit (LVS) presents technical challenges due to the regional anatomy and frequently intramural site of origin. Herein, we demonstrated a case of a successful CA, originating from the LVS region. We further discussed the detailed anatomical background and clinical feasibility of CA as an alternative ablation route for PVCs originating from the LVS.
