Term
coronary artery bypass graft (CABG)
Definition
grafting of a portion of a blood vessel retrieved from another part of the body (such as a length of saphenous vein from the leg or mammary artery fromt he chest wall) to ypass an occluded coronary artery, restoring circulation to myocardial tissue; the traditional method includes temporary arrest of the heart with circulation (bypass) of the patient's blood through a heart-lung machne during the procedure - an alternative off-pump approach uses a stabilizer to perform the procedure nt he beating heart
Term
anastomosis
Definition
opening; joining of two blood vessels to allow flow from one to the other
Term
endarterectomy
Definition
incision and coring of the lining of an artery to clear a blockage caused by a clot or atherosclerotic plaque buildup
Term
transmyocardial revascularization (TMR)
Definition
a laser technique used to open tiny channels in the heart muscle to restore blood flow, thereby relieving angina in patients with advanced coronary artery disease; an option for patients not treatable with angioplasty or coronary artery bypass
Term
valve replacement
Definition
surgery to replace a diseased heart valve with an artifical one - types of artificial valves: tissue -most commonly amde from animal tissue such as porcine (pig) or bovine (cow)

use of a flexible fiberoptic angioscope accompanied by an irrigation system, a camera, a videorecorder and a monitor that is guided through a specific blood vessel to visually assess a lesion and select the mode of therapy
Term
atherectomy
Definition
excision of atheromatous plaque from within an artery utilizing a device housed in a flexible catheter that selectively cuts away or pulverizes tissue buildup
Term
percutaneous transluminal coronary angioplasty
Definition
a method of treating the narrowing of a coronary artery by inserting a specialized catheter with a balloon attachment, then inflating it to dilate and open the narrowed portion of the vessel and restore blood flow to the myocardium; most often includes a placement of stent
Term
intravascular stent
Definition
implantation of a device used to reinforce the wall of a vessel and ensure its patency (openness) - most often used to treat a stenosis or a dissection
