Navigating the Unforeseen: Surgical Intervention for Symptomatic Coronary Aneurysms in Acute Coronary Syndrome

Abstract

Coronary artery aneurysms are defined as luminal enlargements greater than 50% relative to the adjacent reference vessel segment. Most cases can be managed conservatively with medical treatment. Some of them may be symptomatic or even present in the form of the acute coronary syndrome. In such cases, surgical or interventional treatment options should be considered. In addition, the severity of the lesion on coronary angiography may be underestimated at the time of diagnosis. In our case, a coronary aneurysm presenting as an acute coronary syndrome (ACS), aneurysm in the left anterior descending artery (LAD), and critical stenosis, as well as lesions in other coronary arteries, and then treated surgically, is presented.
