Study Description
Brief Summary:
The purpose of this research study is to evaluate the safety and feasibility of the Impella 2.5 Circulatory Support System for use during mapping and ablation of ventricular tachycardia in the setting of Ventricular dysfunction.

Condition or disease Intervention/treatment Phase
Ventricular Tachycardia Device: Impella 2.5 Circulatory Support system insertion Phase 4

Detailed Description:
The Impella 2.5 is a percutaneous heart pump that will be used to provide partial circulatory support -. The Impella 2.5 is approved by the US Food and Drug Administration and is being tested to see if it helps keep the patient's blood pressure stable during the cardiac ablation procedure. The Impella 2.5 Circulatory Support System works by placing a small pump into the left pumping chamber of the heart which will then help the heart circulate blood throughout the body. The Impella 2.5 Circulatory Support system will be removed once the heart no longer needs help with the pumping action which can be at any time from just after the completion of the heart procedure up to several days post procedure as determined by physician.

Arms and Interventions

Arm Intervention/treatment
Circulatory Support System
Percutaneous use of left ventricular assist device, Impella 2.5 Circulatory Support System to facilitate mapping and ablation of ongoing VT by maintaining near-normal hemodynamics, reducing myocardial workload and preservice organ perfusion.
Device: Impella 2.5 Circulatory Support system insertion
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

Outcome Measures

Primary Outcome Measures :
  1. Hemodynamic Support of Impella 2.5 Circulatory Support System [ Time Frame: Inpatient Admission ]
    This study will assess whether there is a satisfactory hemodynamic status during the ablation procedure [during VT Mapping and Ablation Procedure], and whether there is any need for additional circulatory support following the procedure

Secondary Outcome Measures :
  1. Morbidity and Mortality [ Time Frame: Month [30 Days] Follow up ]
    Morbidity and Mortality, as determined by clinical metrics and validated by tests during and immediately post VT Mapping and ablation procedure with cardiac monitoring in hospital and one Month [30 days] follow up telephone interview to assess symptoms, side effects and medication use.
