Intravascular ultrasound can be a crucial tool for diagnosing rare and life-threatening cases of aortic dissection complicated by myocardial ischemia during emergency coronary angiography.
May aid diagnosis of rare AMI with aortic dissection during angiography; leaves open need for prospective validation before wider use.
A 52-year-old man was transferred to our hospital with a sudden onset of severe chest pains. His electrocardiogram revealed ST-segment elevation suggestive of acute myocardial infarction. Emergency coronary angiography showed subtotal occlusion of left main trunk (LMT) with delayed coronary flow. Because intravascular ultrasound revealed a large intimal flap, we diagnosed aortic dissection involving the LMT. After stenting of the LMT, the patient underwent surgical repair of the aortic dissection. Although it is difficult to obtain a correct diagnosis of aortic dissection complicated with myocardial ischemia, we succeeded in diagnosing this rare condition by use of a intravascular ultrasound.

Okamoto (2012) conducted a case report in Acute Myocardial Infarction complicated with Aortic Dissection (n=1). Intravascular ultrasound (IVUS) was evaluated. Intravascular ultrasound successfully diagnosed a rare case of acute myocardial infarction complicated by ascending aortic dissection involving the left main trunk.
