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.
