Study Short Title: MRI in Patients with Biventricular Devices

Study Long Title: Cardiac Magnetic Resonance Imaging in the Setting of Implantable Biventricular Pacemakers to Assess Phenotype Predictors of Benefits

IRB#: 05-07-22-03

Funding Source: National Heart Lung and Blood Institute

Summary of Trial:

Patients undergo MRI of the heart “pre” and more than “8 weeks post” biventricular device implantation to determine if biventricular devices are beneficial to patients with poor heart function.

Inclusions:

Patients who are scheduled to be implanted with biventricular devices, or who are already implanted with a biventricular device and underwent a MRI of the heart pre-implant.

Exclusions:

Patients whose devices are not determined safe to undergo MRI.
Patients with poor renal function (GFR<30 mL/min) who are not candidates for Gadolinium.
Pregnant patients
