René Gerónimo Favaloro was an Argentine cardiac surgeon and educator best known for his pioneering work on<unk>  using the great saphenous vein. saphenous vein grafts – one to the right coronary<unk>  system and one to the obtuse marginal system. There are many variations in terminology, in which one or more of<unk> ", "bypass" or "graft" is left out. The most frequently used acronym for this type of surgery is<unk>  (pronounced 'cabbage'), pluralized as<unk> s (pronounced 'cabbages'). Initially the term aortocoronary bypass (ACB) was more popularly used to describe this procedure. CAGS (coronary<unk>  graft surgery, pronounced phonetically) should not be confused with coronary angiography (CAG). Number of<unk> es bypassed Illustration depicting single, double, triple, and quadruple bypass The terms single bypass, double bypass, triple bypass, quadruple bypass and quintuple bypass refer to the number of coronary<unk> es bypassed in the procedure. In other words, a double bypass means two coronary<unk> es are bypassed (e.g., the left anterior descending (LAD) coronary<unk>  and right coronary<unk>  (RCA)); a triple bypass means three vessels are bypassed (e.g., LAD, RCA and left circumflex<unk>  (LCX)); a quadruple bypass means four vessels are bypassed (e.g., LAD, RCA, LCX and first diagonal<unk>  of the LAD) while quintuple means five. Left main coronary<unk>  obstruction requires two bypasses, one to the LAD and one to the LCX. A coronary<unk>  may be unsuitable for bypass grafting if it is small (< 1 mm or < 1.5 mm), heavily calcified, or located within the heart muscle rather than on the surface. A single obstruction of the left main coronary<unk>  is associated with a higher risk for a cardiac death and usually receives a double bypass. The surgeon reviews the coronary angiogram prior to surgery and identifies the number of obstructions, the percent obstruction of each, and the suitability of the<unk> es beyond the as targets. The presumed number of bypass grafts needed as well as the location for graft attachment is determined in a preliminary fashion prior to surgery, but the final decision as to number and location is made during surgery by direct examination of the heart.
