Study Short Title: MRI in Patients Undergoing Cardiac Ablation for Ventricular Tachycardia

Study Long Title: Cardiac Magnetic Resonance Imaging in the Setting of Implantable Cardioverter Defibrillators to Assess Substrate for Ventricular Tachycardia

IRB#: 05-07-22-02

Funding Source: National Heart Lung and Blood Institute/ The Donald W. Reynolds Foundation

Summary of Trial:

Patients with implanted cardiac defibrillators who are scheduled to have a cardiac ablation for ventricular tachycardia undergo an MRI of the heart “pre” procedure to identify scar and to help guide the ablation. Some patients also undergo MRI post procedure and 8 weeks post procedure to help determine whether or not the ablation was successful.

Inclusions: Patients with and ICD; history of ventricular tachycardia and poor heart function in whom myocardial scar is presumed to be identifiable on MRI.

Exclusions:

Patients whose ICD’s are not safe to undergo MRI.
Patients with poor renal function (GFR<30 mL/min) who are not candidates for Gadolinium.

Clinical Trial Site:

Johns Hopkins Hospital
Blalock 5
600 N.Wolfe Street
Baltimore, Md. 21205

Compensation:

$150.00 for the post procedure MRI only (the pre-procedure MRI is considered standard of care for patients undergoing VT ablation).

Start Date: 8-30-05

Anticipated End Date: 8-30-10
