Abstract
Key Clinical MessageIdiopathic ventricular tachycardia arising from the LV summit epicardial area can be successfully mapped and possibly ablated from the left atrial appendage.
Highlights
The left ventricular (LV) summit is a common site from where idiopathic premature ventricular contraction (PVC) and ventricular tachycardia (VT) can originate.Catheter ablation of the LV summit can pose various anatomical challenges, and foci located deep in the myocardium often need more extensive ablation to surround the area from where it originates, in order to be successful.We present a case of idiopathic VT arising from the LV summit area, where the left atrial appendage was used as a vantage point to successfully map and ablate the epicardial aspect of the septal LV/LV summit area
Key Clinical Message Idiopathic ventricular tachycardia arising from the LV summit epicardial area can be successfully mapped and possibly ablated from the left atrial appendage
This approach can supplement the epicardial mapping of the LV summit currently performed via the great cardiac vein (GCV) and the anterior interventricular vein (AIV), or replace it when the veins are not approachable due to anatomical challenges
