Abstract

Coronary artery aneurysms have an incidence of 0.3% to 5.3% following percutaneous transluminal coronary angioplasty.
A 75-year-old woman presented with dyspnea on exertion and chest discomfort. In 2004 she underwent percutaneous coronary intervention to the left anterior descending artery (LAD) and, in 2010, a ST-segment elevation myocardial infarction was treated with another LAD stent. On this admission, catheterization revealed a large proximal LAD coronary aneurysm at the site where the last stent was placed. She underwent successful LAD aneurysm repair with end-to-end saphenous vein graft interposition and end-to-side bypass to the diagonal branches.
The most common surgical procedures are ligation and coronary artery bypass graft. In our case, the diagonal branches were too small to perform epicardial bypasses.
Repair of coronary aneurysm with interposition of saphenous vein graft re-establishes flow to the main vessel and tributaries. Adequate exposure and meticulous techniques are essential for success.
