Biventricular Impella support, specifically requiring right-sided assistance, enabled hemodynamic stability and safely reduced ventricular tachycardia burden in severe dilated cardiomyopathy.
Biventricular Impella support can provide necessary hemodynamic stability for high-risk ventricular tachycardia ablation in patients with severe biventricular failure.

ABSTRACT Ventricular tachycardia (VT) ablation in patients with severely impaired left ventricular (LV) function remains challenging because mapping often requires VT induction or sustained arrhythmia that may not be tolerated. Temporary mechanical circulatory support (tMCS) can improve procedural stability in high‐risk patients. We report a successful VT ablation in a 73‐year‐old man with non‐ischemic dilated cardiomyopathy, severe biventricular failure, and recurrent VT, performed under fully percutaneous biventricular support using Impella CP and Impella RP (Abiomed) via transfemoral access. Hemodynamic stability was achieved only after the addition of right‐sided support. The procedure reduced VT burden without device‐ or access‐related complications.
