Surgical Correction of an Atherosclerotic Coronary Artery Aneurysm

Summary

A 56-year-old male patient became symptomatic with angina pectoris. Selective coronary angiography revaaled an aneurysm of the stem of the circumflex artery and a subtotal stenosis of the left anterior descending coronary artery (LAD). At cardiac surgery the anterior wall of the aneurysm was resected and the resulting defect closed with a venous patch. Bypass grafts to the LAD and the first marginal branch were also implanted. Three months later both grafts were shown to be patent, and flow through the reconstructed stem of the circumflex artery was undisturbed.
