What is multiple bypass surgery or multiple CABG?
Bypass surgery is a cardiac procedure performed to route blood flow around clogged arteries supplying the heart. The purpose of this procedure is to improve blood flow and oxygen to the heart. Depending on the number of coronary arteries (arteries that bring blood to the heart muscle) bypassed in the procedure, the surgery may be termed single bypass, double bypass (CABG-2x), triple bypass (CABG-3x), quadruple bypass (CABG-4x) and quintuple bypass (CABG-5x). A double bypass means two coronary arteries are bypassed (e.g. the left anterior descending (LAD) coronary artery and right coronary artery (RCA)); a triple bypass means three vessels are bypassed (e.g. LAD, RCA, left circumflex artery (LCX)); a quadruple bypass means four vessels are bypassed (e.g. LAD, RCA, LCX, first diagonal artery of the LAD) while quintuple means five. Less commonly more than four coronary arteries may be bypassed. A greater number of bypasses does not imply a person is “sicker,” nor does a lesser number impl
