myocardial revascularization
Surgical restoration of blood flow to areas of heart muscle affected by coronary artery disease.
Full Definition
Myocardial revascularization encompasses surgical procedures designed to restore adequate blood flow to ischemic myocardium. This includes coronary artery bypass grafting using various conduits (arterial or venous), as well as hybrid procedures combining surgical and percutaneous interventions. The goal is to improve symptoms, enhance quality of life, and potentially improve survival in patients with significant coronary artery disease. Complete revascularization aims to restore flow to all viable myocardial territories, while incomplete revascularization may be acceptable in certain clinical scenarios.
Usage
Usage note: Distinguish from percutaneous coronary intervention, which is catheter-based.
