Percutaneous Hemodynamic Support With Impella 2.5 During Scar-related Ventricular Tachycardia Ablation

Femoral angiography will be performed, and if the anatomy is suitable, the femoral artery preclosure technique will be employed. The Impella 2.5 will be inserted through th femoral artery into the left ventricle. Anti-coagulation will be titrated to achieve a therapeutic ACT level. Organ perfusion and Hemodynamic data will be collected during simulated VTs and throughout the course of the case. The performance level of the device may be adjusted during the case to quantify hemodynamic effects
