Key result
Epicardial access proves feasible for VT ablation in a patient with an EV-ICD.
Why the study?
Epicardial access in a patient with an extra-vascular implantable cardioverter defibrillator (EV-ICD) had not been previously described.
Case Report (n=1)
This report provides the first description of epicardial access for ventricular tachycardia ablation in a patient with an extra-vascular ICD.
Single-case report suggests epicardial VT ablation feasibility with extra-vascular ICD; hypothesis-generating and requires prospective validation.
The recognition of the importance of epicardial substrate in ventricular arrhythmias has led to an increased use of epicardial mapping and radiofrequency catheter ablation. The subxiphoid approach remains the standard and most frequently used route for percutaneous epicardial access.1,2 However, the emergence of new technologies can necessitate re-examination of existing techniques. Epicardial access in a patient with an extra-vascular implantable cardioverter defibrillator (EV-ICD) has not been previously described.

Somasundaram et al. (2026) conducted a case report in Ventricular tachycardia with an extra-vascular ICD (n=1). Epicardial access for ventricular tachycardia ablation was evaluated. Epicardial access for ventricular tachycardia ablation in a patient with an extra-vascular implantable cardioverter defibrillator is described.
