Hydrodissection for pericardial adhesion in percutaneous epicardial ventricular tachycardia ablation

Abstract

Epicardial ablation in patients with pericardial adhesions is challenging. This case is the first report of successful epicardial ventricular tachycardia ablation by combining hydrodissection with the previously reported blunt dissection techniques for pericardial adhesions. This approach demonstrates a promising technique for managing similar cases where traditional methods may fail, providing a safer and more effective solution for epicardial ablation in patients with pericardial adhesions.
