Transendocardial delivery of vascular endothelial growth factor gene in infarcted and peri-infarcted myocardium under MR-guidance improved 3D (radial, circumferential and longitudinal) strain within 50 days and caused significant reduction in infarct transmurality of treated animals compared to controls. Cine and tagging MRI are sensitive techniques for monitoring the effects of locally delivered therapies.
