Transcoronary Ethanol Ablation for Recurrent Ventricular Tachycardia After Failed Catheter Ablation

Abstract

In patients with difficult-to-control VT in whom RFCA fails, TCEA prevents all VT recurrences in 36% and improves arrhythmia control in an additional 27%. Inadequate target vessels, collaterals, and recurrence of modified VTs limit efficacy, but TCEA continues to play an important role for difficult VTs in these high-risk patients.
