Aortic Dissection With Complete Occlusion of Left Main Coronary Artery Presenting as Acute ST-Segment Elevation Myocardial Infarction.

Acute Aortic Dissection (AAD) is a life-threatening condition, which presents with a wide variety of symptoms ranging from being asymptomatic to sudden cardiac death. A retrograde extension of AAD can lead to partial or complete occlusion of coronary vessels, leading to an exceedingly rare presentation in the form of acute Myocardial Infarction (MI). A prognosis of AAD depends on prompt diagnosis and urgent surgical intervention to re-establish coronary blood flow. Here, we report a case of AAD, presenting as acute anterolateral wall MI, due to total occlusion of the left main coronary artery.
