Implication

May support Impella use for unstable VT ablation in select cases; hypothesis-generating and requires prospective confirmation.

Key Points

To evaluate the feasibility and safety of using a microaxial blood pump to maintain hemodynamic stability during catheter ablation for unstable ventricular tachycardia.
Case series evaluating the use of the Impella microcirculatory axial blood flow pump during catheter ablation procedures (N=3).
Assessed patients presenting with hemodynamically unstable ventricular tachycardia that caused severe hypotension during arrhythmia induction.
Mechanical circulatory support enabled stable electrophysiological mapping and successful completion of catheter ablation in all 3 patients.
No device-related complications were observed, including absence of valvular disturbance, iatrogenic ventricular arrhythmias, or mechanical interference with catheter movement.
