Ablation of Epicardial Macroreentrant Ventricular Tachycardia Associated with Idiopathic Nonischemic Dilated Cardiomyopathy by a Percutaneous Transthoracic Approach
Key result
Percutaneous transthoracic epicardial mapping and ablation successfully terminated VT without recurrence during long-term follow-up in a patient with idiopathic dilated cardiomyopathy.

Implication
Single-case success supports epicardial VT ablation feasibility; hypothesis-generating and should not change practice without prospective data.

Population
1 patient with idiopathic dilated cardiomyopathy, frequent VT, and previously unsuccessful endocardial ablation followed long-term.
I
Intervention
Percutaneous transthoracic epicardial mapping and low-power radiofrequency ablation of the central isthmus of a figure-of-eight macroreentrant circuit
O
Outcome
Termination of VT, non-inducibility, and recurrence during long-term follow-up
Percutaneous transthoracic epicardial ablation can successfully treat macroreentrant VT associated with epicardial scar in patients with idiopathic nonischemic dilated cardiomyopathy.
Cite This Study
Swarup et al. (2002) conducted a case report in Epicardial ventricular tachycardia associated with idiopathic nonischemic dilated cardiomyopathy (n=1). Percutaneous transthoracic epicardial mapping and ablation was evaluated on VT termination and recurrence. Percutaneous transthoracic epicardial mapping and ablation successfully terminated VT without recurrence during long-term follow-up in a patient with idiopathic dilated cardiomyopathy.
