Acute Coronary Syndrome in a 40-Year-Old Male With Coronary Ectasia: A Case Report.

Coronary artery ectasia (CAE) is a relatively uncommon condition that is often identified incidentally during coronary angiography. It can lead to altered hemodynamics and an increased risk of thrombotic events. This case report outlines the clinical progression of a 40-year-old male diagnosed with acute coronary syndrome (ACS). Coronary angiography demonstrated complete occlusion of the ectatic left circumflex artery (LCx) and dominant right coronary artery. The patient underwent thrombus aspiration, which reinstated normal coronary flow (TIMI III) and uncovered a large eccentric, ball-like thrombus within the vessel. Stenting was not feasible due to the size of the ectasia. This case illustrates the diagnostic and therapeutic challenges in managing ACS in patients with CAE and emphasizes the need for additional research to determine optimal treatment strategies for enhancing long-term outcomes.
