A Novel Hybrid Approach to the Treatment of a Left Main Coronary Artery Aneurysm

A 66-year-old man with a ramus chronic total occlusion had escalating angina and a high-risk stress test. Coronary angiography the day of his planned ramus chronic total occlusion percutaneous coronary intervention demonstrated a large left main aneurysm. He underwent bypass with left internal mammary artery left anterior descending and failed saphenous vein graft ramus, followed by successful covered stent placement from left main into left circumflex and ramus chronic total occlusion percutaneous coronary intervention.
