Figure 3 Representative maps of the regional myocardial beta-galactosidase protein expression after catheter-based selective pressure-regulated retroinfusion of the anterior cardiac vein (retroinfusion), surgical intramyocardial direct injection (IMD), and percutaneous intramyocardial injection (PIMD). Each map represents one animal. ENDO = subendocardial probe; EPI = epicardial probe; MID = midmyocardial probe. Open bars = EPI; solid bars = MID; hatched bars = ENDO.
