A porcine model of ischemic heart failure produced by intracoronary injection of ethyl alcohol.

We have developed a porcine model of acute myocardial infarction (AMI) and ischemic heart failure by transcatheter intracoronary injection of ethyl alcohol and observed pathologic changes induced in the alcohol-injured coronary artery and infarcted myocardium. In a total of 12 female pigs, anteroseptal AMI was induced by transcatheter delivery of 1 mL of 99.9% ethyl alcohol using a 2.
