| coronary bypass surgery | A surgical procedure, known as a coronary artery bypass graft, which involves replacing diseased (narrowed) coronary arteries with veins obtained from the patients lower extremities (autologous graft). During this procedure the patient is placed on a heart bypass machine (heart-lung machine) to allow the surgeon adequate time to perform surgery on the resting (nonbeating) heart. This procedure has proven to extend the lives of individuals with coronary artery disease and improve the quality of life. Recovery in the hospital is approximately 7-10 days. (27 Sep 1997) |
