Two patients who developed coronary aneurysm at the site of Percutaneous Transluminal Coronary Angioplasty (PTCA) in proximal LAD accompanied by severe re-stenosis just proximal to the aneurysm are described. Both patients underwent Coronary Arterial Bypass Grafting (CABG) to distal LAD to stop anginal attacks refractory to any anti-anginal drugs and to prevent a rupture of a coronary aneurysm. After the operation the anginal attacks disappeared and no trace of coronary aneurysm was visible in the coronary angiogram.
