A Case of Acute Myocardial Infarction due to Left Main Trunk Occlusion Complicated With Aortic Dissection as Diagnosed by Intravascular Ultrasound
نویسندگان
چکیده
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.

In this issue of the Journal, Pinney and Wasserman describe the case of a patient who survives acute aortic dissection complicated by occlusion of the left main coronary ostium and anterior myocardial infarction (MI), due in part to the fortuitous presence of an anomalous left circumflex artery. The case illustrates the challenges of diagnosing aortic dissection, even in the current era of accu...

A n 83-year-old woman with a history of fever presented with severe chest pain progressing to cardiogenic shock. Her electrocardiogram showed evidence of anteroseptal myocardial infarction (MI).

Drug-eluting stents were successfully implanted from the LMT into...

We report here on a case of ascending aortic dissection combined with anterior myocardial infarction that was caused by a retrograde dissection into the left main coronary trunk and proximal left anterior descending artery. We successfully treated this with stenting of the left main coronary artery and proximal left anterior descending artery, and this allowed for the definitive surgical correc...

Acute myocardial infarction (AMI) due to the occlusion of the left main coronary artery (LMCA) is a rare but serious condition in the era of percutaneus coronary intervention (PCI). Even more rare is AMI involved with both LMCA and its branches like trifurcartion or bifurcation: this is challenging for interventional cardiologists, because it involves the extension of the myocardium complicated...

A 69-year-old man was transferred to our hospital with a diagnosis of acute type A aortic dissection. In the emergent operation, the dissection was found to extend to the orifice of the left coronary artery, but not to the coronary artery itself. The false lumen was closed using glue and sutures with felt strips, and graft replacement of the ascending aorta was performed. However, signs of myoc...
