Aortic pressures within a giant right coronary artery aneurysm

Giant coronary artery aneurysms are rare conditions with potentially devastating consequences. We report a case of the largest documented giant right coronary artery (RCA) aneurysm to date.

A 57-year-old male patient visited our outpatient clinic for abdominal pain and exertional dyspnea. Computed tomography identified a 10.2 × 9.8 cm RCA aneurysm with RCA pressure waves were similar to aortic pressures. After discussion by the cardiac team, elective resection with ligation of the proximal and distal ends of the RCA was performed due to the presence of adequate collaterals.

We highlight the challenges related to the management of patients presenting with giant coronary artery aneurysms. Optimal management strategies and outcomes for such rare cardiovascular conditions implies the need for standardised management guidelines.
