Giant right coronary artery aneurysm following percutaneous transluminal coronary angioplasty

Coronary artery aneurysm following percutaneous coronary angioplasty (PTCA) is rare in interventional cardiology. Several factors may contribute to the development of such complication following PTCA that include stent size, improper apposition, nature of vascular disease, and operative technique. Here, we report a case of giant right coronary artery in-stent restenosis and aneurysm following PTCA stenting within 1-month duration. The operative technique, underlying diseased segment of coronary artery, and associated comorbidities are contributing factors for such complications. Bedside echocardiography may detect aneurysm and expedite the process of treatment.
