In medicine, myocardial revascularization is "the restoration of blood supply to the myocardium."[1]
Revascularization procedures include:
- Coronary artery bypass grafting(CABG) which is a "surgical therapy of ischemic coronary artery disease achieved by grafting a section of saphenous vein, internal mammary artery, or other substitute between the aorta and the obstructed coronary artery distal to the obstructive lesion."[2]
- Percutaneous transluminal coronary angioplasty (PCTA) (angioplasty of a coronary artery) is "dilatation of an occluded coronary artery (or arteries) by means of a balloon catheter to restore myocardial blood supply."[3]
- Coronary atherectomy which is a "percutaneous transluminal procedure for removing atheromatous plaque from the coronary arteries. Both directional (for removing focal atheromas) and rotational (for removing concentric atheromatous plaque) atherectomy devices have been used."[4]
Coronary artery bypass is more effective for myocardial revascularization of coronary heart disease than percutaneous transluminal coronary angioplasty[5], especially for patients with diabetes who have stenosis of three coronary arteries.[6] Coronary artery bypass is also more effective than percutaneous transluminal coronary angioplasty with drug-eluting stents.[7] The SYNTAX score may help determine choice of procedure for myocardial revascularization.[8]
