This is a cabbage: coronary artery bypass graft (CABG) surgery, and colloquially heart bypass or bypass surgery, is a surgical procedure consisting of either diverting the left internal thoracic artery (left internal mammary artery or "LIMA") to the left anterior descending (LAD) branch of the left main coronary artery; or a harvested great saphenous vein of the leg, attaching the proximal end to the aorta or one of its major branches, and the distal end to immediately beyond a partially obstructed coronary artery (the "target vessel") - usually a 50% to 99% obstruction @medicalcortex #medicalschool #medstudent #nurse #doctor #heart #heartsurgery #surgery #surgeon #f4f #l4l #usmle #premed #medicine #medical #artery #cabg #emergency #bypass
