Idiopathic premature ventricular contractions (PVCs) most often occur under or above the semi-lunar valves from the right ventricular outflow tract and less often from the left ventricular outflow tract. Radio-frequency ablation is mostly used for patients who develop left ventricular dysfunction or intolerable symptoms. Since most of the patients are in the young age group and ablation has a high success rate with recurrence being relatively low, it can be offered to those symptomatic patients who want a definitive cure. The use of 3-dimensional (3D) electroanatomic mapping systems helps locate the ablation site. We report a case of a young man with PVCs coming from a rare site of non-coronary cusp, which was ablated successfully by using a high-density mapping system. Key Words: Catheter ablation, Left ventricular outflow tract, Non-coronary aortic cusp, Premature ventricular contractions.
