Zero-fluoroscopy catheter ablation of premature ventricular contractions at left coronary cusp near left main coronary artery.

The left coronary cusp is the commonest site of origin for coronary cusp PVC. Catheter ablation without fluoroscopy is highly effective, feasible, and safe but it could be related to risks because of proximity to the coronary arteries. The use of ICE integration allowed an improvement in the safety and efficiency of these procedures.
