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

Key Clinical Message: CA of LVS premature beats complexes is difficult due to anatomical limitations. We report a patient with PVCs originating from the LVS region who was successfully ablated by 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. [ABSTRACT FROM AUTHOR]
