In Cardiac Resynchronization Therapy (CRT), the location
of the left ventricular (LV) lead plays an important
role in dictating patient benefit. The LV lead is
delivered through the coronary veins and should be
ideally implanted at the latest contracting site that is
not predominantly myocardial scar. Since the coronary
veins are not imaged until CRT procedure, it is unknown
whether a desired implantation location has coronary
vein access. The objective of this study is to evaluate
the potential of MRI to image the coronary vein branch
used for LV lead implantation with validation against
the gold standard, retrograde x-ray venography.
