Highlights the electrocardiographic recognition and minimally invasive ablation through coronary sinus branches for idiopathic epicardial ventricular tachycardias.
Supports targeted ablation in select epicardial VT; hypothesis-generating pending prospective validation.
Idiopathic epicardial ventricular tachycardias (VTs) account for 9% of idiopathic VTs. The recognition of this entity is important, as a minimally invasive ablation procedure performed exclusively through the coronary sinus branches may be considered, avoiding the potential risks associated with access to the left ventricular endocardium, the aortic root, and the pericardial space. The electrocardiographic features and therapeutic management of this rare form of tachycardia are discussed.
