Radiofrequency ablation of an epicardial ventricular tachycardia through the great cardiac vein in a patient with mitro-aortic mechanical prostheses.
OBJECTIVE
Prior cardiac surgery limits epicardial ventricular tachycardia (VT) ablation due to epicardial adhesions formation.


RESULTS
We describe an epicardial VT ablation through the coronary venous system in a patient with mechanical mitro-aortic prostheses. The different possible ablation approaches and their potential limitations are discussed.


CONCLUSIONS
In selected patients, especially after cardiac surgery, coronary venous system approach can be considered as a safety possible approach for the ablation of some epicardial VTs.
