This case report provides the first in vivo angiographic demonstration that acute aortic dissection can cause myocardial infarction via compression of the right coronary artery by the false lumen.
Highlights potential MI mechanism in aortic dissection; first angiographic demonstration leaves open validation in larger cohorts.
Acute aortic dissection may present a clinical picture simulating myocardial infarction, including electrocardiographic changes. The mechanism underlying this mode of presentation has not heretofore been documented during life. We present here for the first time, a patient with acute aortic dissection and the clinical picture of acute myocardial infarction, where the mechanism of infarction has been demonstrated, by preoperative angiographic studies, probably to be due to compression of the extramural portion of the right coronary artery by the false channel of the dissecting hematoma.
