A multivessel spontaneous coronary artery dissection presented with an acute coronary syndrome that was conservatively managed. A case report

A spontaneous coronary artery dissection (SCAD) is a tear that forms in a blood vessel in the heart without any obvious underlying etiology. It could be a single vessel or multiple vessels. We present a 48-year-old male known to be a heavy smoker without any chronic diseases or family history of heart disease who presents to the cardiology outpatient clinic with shortness of breath and chest pain on exertion. Electrocardiography demonstrated ST depression with T wave inversion of anterior leads, while echocardiography of the patient showed left ventricular systolic dysfunction with severe mitral regurgitation and mildly dilated left chambers. Based on his risks for coronary artery disease, his electrocardiography, and echocardiography, the patient was referred for elective coronary angiography to exclude the possibility of coronary artery disease. The angiography was done with the result of multivessel spontaneous coronary artery dissections involving the left anterior descending artery (LAD) and circumflex artery (CX) with a normal dominant right coronary artery (RCA). Due to the multi-vessel involvement of the dissection and the high risk of extension of the dissection, we preferred conservative management, including smoking cessation and heart failure management. The patient is doing well with regular heart failure treatment in cardiology follow-up.
