MRI evaluation of local myocardial treatments: epicardial versus endocardial (Cell-Fix catheter) injections.

Aims: We compared two procedures for local myocardial treatment: transepicardial versus transendocardial catheter injection. Transepicardial injections were performed under direct surgical visualization whereas transendocardial injections were performed using electrophysiological guidance.

Methods: A left ventricle (LV) myocardial infarction (MI) was surgically created in 14 sheep.
