Fig. 5From: Cryoinjury-induced acute myocardial infarction model and ameroid constrictor-induced ischemic heart disease model in adult micro-mini pigs for preclinical studiesCoronary angiography for CI or AC- induced CAD models. a AC apparently occluded the proximal region of the LAD. Scale bar: 1Â cm. LAD; left anterior descending artery. AC; ameroid constrictor. b and c Representative figures with coronary angiography (CAG) of AC-induced infarcted hearts. AC sometimes failed to occlude the artery completely (red arrow). Note: functional collateral arteries usually developed to bridge collateral from left main trunk artery to the LAD (yellow arrows). d Representative figure of CAG in a CI-induced infarcted heart. There is no obvious development of a collateral arteryBack to article page
