The CARTO-UNIVU mapping system can facilitate safe epicardial ablation in patients with ARVC by overlaying 3D anatomic maps on coronary angiograms to avoid coronary injury.
Catheter ablation of ventricular tachycardia (VT) in patients with arrhythmogenic right ventricular cardiomyopathy (ARVC) is challenging.1–4 A complex and predominantly epicardial substrate in the basal right ventricular free wall increases the risk of coronary injury during ablation.5 The CARTO-UNIVU mapping system (Biosense Webster Inc, Diamond Bar, CA) permits detailed voltage mapping as well as overlaying of the 3-dimensional (3D) anatomic map on the coronary angiogram. We present an epicardial ablation case of a patient with ARVC in whom the CARTO-UNIVU system facilitated identification of the most critical targets for ablation and avoidance of coronary artery injury.
