Key result
Delayed enhancement magnetic resonance imaging successfully identified a predominantly epicardial infarct, guiding a necessary pericardial approach for ventricular tachycardia ablation.
Case Report (n=1)
Delayed enhancement MRI can effectively guide the approach for substrate-based catheter ablation of epicardial ventricular tachycardia by defining the location and transmural extent of infarcted tissue.
MRI may guide pericardial access for epicardial VT ablation; hypothesis-generating and requires prospective validation before wider use.
Delayed enhancement magnetic resonance imaging is known for its ability to identify scarred myocardial tissue. This case report describes the use of MR imaging to define the location and transmural extent of infarcted tissue in a 45-year-old woman with an anomalous right coronary artery and hemodynamically unstable ventricular tachycardia. By demonstrating a predominantly epicardial infarct, MR imaging indicated that the pericardial approach was necessary for successful substrate-based ventricular tachycardia ablation.

Neužil et al. (2007) conducted a case report in Hemodynamically unstable ventricular tachycardia related to an anomalous right coronary artery (n=1). Delayed enhancement magnetic resonance imaging was evaluated on Identification of infarct location and successful ablation. Delayed enhancement magnetic resonance imaging successfully identified a predominantly epicardial infarct, guiding a necessary pericardial approach for ventricular tachycardia ablation.
