aortocoronarien

Aortocoronarien is an adjective used in medical French to denote relations between the aorta and the coronary arteries. In practice, the term is most commonly encountered in reference to the pontage aortocoronarien, known in English as coronary artery bypass grafting (CABG).

CABG is a revascularization procedure intended to restore blood flow to areas of the heart supplied by diseased coronary arteries. It involves grafting a vessel to create a detour around an obstructed segment, usually by connecting the graft to the aorta and to the coronary artery beyond the blockage. Common conduits include the left internal mammary artery (LIMA) to the left anterior descending artery, and saphenous vein grafts or radial artery grafts for other targets. The operation is often performed with cardiopulmonary bypass, but off-pump techniques exist.

Indications for CABG include multivessel coronary disease, significant left main disease, and diabetes with diffuse atherosclerosis where percutaneous intervention is less favorable. Alternatives include percutaneous coronary intervention or optimized medical therapy, depending on the pattern of disease and patient factors.

Outcomes of CABG include relief of angina and, in select groups (notably left main or triple-vessel disease), potential survival benefit. Complications may include perioperative mortality, stroke, myocardial infarction, infection, and rhythm disturbances. Long-term graft patency varies by conduit, with internal mammary artery grafts generally showing superior durability compared to vein grafts.

Recovery typically involves several days in hospital followed by cardiac rehabilitation and gradual return to activity.
