Abstract

Both myocardial contrast echocardiography (MCE), obtained by intracoronary injection of sonicated Ioxaglate, and dobutamine echocardiography (DE) were performed before and after percutaneous transluminal coronary angioplasty (PTCA) in a patient with recent myocardial infarction,an occluded infarct related artery (IRA) and collateral flow. An opposite response to low and high dose dobutamine (increase and decrease in regional contractility, respectively) suggested the presence of viable myocardium at jeopardy in the infarcted area. This myocardial area was exclusively perfused by collateral circulation (demonstrated by MCE) supplied by an angiographically normal left coronary artery. After PTCA, right coronary artery flow was re-established and angiographically demonstrated collateral flow disappeared. MCE showed a normal rightcoronary artery perfusion bed and relevant overlap areas after left coronary MCE injection. Dobutamine echocardiography performed after PTCA demonstrated persistence of viability, but disappearence of myocardial ischemia.
