Procedural and clinical outcomes after catheter ablation of unstable ventricular tachycardia supported by a percutaneous left ventricular assist device.

Background: Hemodynamic support using percutaneous left ventricular assist devices (pLVADs) during catheter mapping and ablation of unstable ventricular tachycardia (VT) can provide effective end-organ perfusion. However, its effect on procedural and clinical outcomes remains unclear.

Objective: To retrospectively evaluate the procedural and clinical outcomes after the catheter ablation of unstable VT with and without pLVAD support.
