Acute ST-segment Elevation Myocardial Infarction in Kommerell's Diverticulum with a Right-sided Aortic Arch

coronary Kommerell’s diverticulum is a very rare congenital aortic arch anomaly with an estimated incidence of 0.04-0.1%. Few studies have reported on acute ST-segment elevation myocardial infarction in patients with Kommerell’s diverticulum on the right-sided aortic arch. The anatomical anomaly makes coronary artery catheterization difficult. If such a case is suspected during the patient examination before coronary artery revascularization, the appropriate arterial approach site should be carefully considered for revascularization as early as possible.
