Role of High-Resolution Image Integration to Visualize Left Phrenic Nerve and Coronary Arteries During Epicardial Ventricular Tachycardia Ablation
2015
Circulation: Arrhythmia and Electrophysiology
Preserved Fulltext
Background-Epicardial ventricular tachycardia (VT) ablation is associated with risks of coronary artery (CA) and phrenic nerve (PN) injury. ...
Elimination of local abnormal ventricular activities (LAVAs) was used as ablation end point. The distribution of CAs/PN with respect to LAVA was analyzed and compared between VT etiologies. ...
B, LAVAs registered to MDCT-defined coronary arteries/phrenic nerve (PN) and computed tomography (CT)-defined substrate: most LAVAs located inside the CT-defined structural substrate (wall thinning <5 ...
