coronary revascularization
Surgical or percutaneous procedures to restore blood flow to ischemic myocardium through bypass grafting or angioplasty with stenting.
Full Definition
Coronary revascularization encompasses both surgical and percutaneous interventions designed to restore adequate blood flow to ischemic myocardium by bypassing or opening stenotic coronary arteries. The two primary approaches are coronary artery bypass grafting (CABG), which uses arterial or venous grafts to create alternative pathways around blocked arteries, and percutaneous coronary intervention (PCI), which involves balloon angioplasty and stent placement to open narrowed vessels. The choice between approaches depends on factors including coronary anatomy, number of diseased vessels, left ventricular function, diabetes status, and patient surgical risk. Revascularization is indicated for patients with significant coronary stenoses causing symptoms refractory to medical therapy or those at high risk for cardiovascular events. Both procedures require comprehensive secondary prevention strategies including antiplatelet therapy, statins, and aggressive risk factor modification.
Usage
Usage note: Encompasses both surgical (CABG) and percutaneous (PCI) approaches; specify method when describing specific procedures.
