Unusual evolution of an aneurysm of the proximal left anterior descending coronary artery 15 years after a Simpson atherectomy




A 37-year-old woman presented in 1993 with unstable angina. She had a history of hypertension, hypercholesterolaemia, tobacco use and family history of cardiovascular disease. She underwent a coronary angiogram (CA) that revealed severe stenosis of the proximal left anterior descending (LAD) coronary artery. The lesion was treated successfully by balloon angioplasty. She presented 3 weeks later with recurrent angina and subsequently underwent a new CA that revealed diffuse restenosis of the proximal LAD coronary artery. The lesion was treated successfully by Simpson atherectomy ( Fig. 1 ) and the patient was discharged with the following treatment: aspirin, atorvastatin, nifedipine and diltiazem, allowing optimal control of risk factors. In 1994, the patient underwent a systematic control CA that revealed an aneurysm of the proximal LAD ( Fig. 2 ). Thereafter, she was followed clinically every year and remained asymptomatic for 15 years. During this period, the patient underwent repeated stress myocardial scintigraphy that remained negative.
