coronairrevasculaire

Coronary revascularization is a set of medical procedures aimed at restoring adequate blood flow to the heart muscle in people with obstructive coronary artery disease. The primary goals are to relieve angina, improve exercise tolerance, and reduce the risk of heart-related complications in selected patients. The term coronairrevasculaire is used in some languages as a direct translation of this concept.

The two main approaches are percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG). PCI is a minimally invasive method that opens narrowed coronary segments using balloon dilation, often followed by placement of a stent to keep the artery open. Stents may be bare-metal or drug-eluting, and access is usually via the radial or femoral artery. PCI is typically associated with shorter hospital stays and quicker return to activity, but restenosis or stent-related thrombosis can occur, and its suitability depends on the location and extent of disease.

CABG is a surgical procedure that creates new routes for blood flow by grafting vessels from other parts of the body (commonly the internal mammary artery or saphenous vein) to bypass blocked arteries. CABG is often favored for complex multivessel disease, left main disease, or in diabetics, where long-term patency may be superior. Recovery is longer than after PCI, but graft durability can be greater in certain patient groups.

Decision-making involves coronary angiography and functional assessments, with a heart-team approach to determine the most appropriate strategy based on anatomy, comorbidities, and patient preferences. Risks include bleeding, infection, stroke, myocardial infarction, and graft or stent failure.
