<P> CABG is one of the most common procedures performed during U.S. hospital stays; it accounted for 1.4% of all operating room procedures performed in 2011 . Between 2001 and 2011, however, its volume decreased by 46%, from 395,000 operating procedures performed in 2001 to 213,700 procedures in 2011 . </P> <P> Between 2000 and 2012, the number of CABG procedures carried out decreased across the majority of OECD countries . However, there remained substantial variation in the rate of procedures, with the U.S. carrying out four times as many CABG operations per 100,000 people as Spain . These differences do not appear to be closely related to the incidence of heart disease, but may be due to variation in financial resources, capacity, treatment protocols and reporting methods . </P> <Ul> <Li> The first coronary artery bypass surgery was performed in the United States on May 2, 1960, at the Albert Einstein College of Medicine - Bronx Municipal Hospital Center by a team led by Robert H. Goetz and the thoracic surgeon, Michael Rohman with the assistance of Jordan Haller and Ronald Dee . In this technique the vessels are held together with circumferential ligatures over an inserted metal ring . The internal mammary artery was used as the donor vessel and was anastomosed to the right coronary artery . The actual anastomosis with the Rosenbach ring took fifteen seconds and did not require cardiopulmonary bypass . The disadvantage of using the internal mammary artery was that, at autopsy nine months later, the anastomosis was open, but an atheromatous plaque had occluded the origin of the internal mammary that was used for the bypass . </Li> <Li> Soviet cardiac surgeon, Vasilii Kolesov, performed the first successful internal mammary artery--coronary artery anastomosis in 1964 . However, Goetz has been cited by others, including Kolesov, as the first successful human coronary artery bypass . Goetz's case has frequently been overlooked . Confusion has persisted for over 40 years and seems to be due to the absence of a full report and to misunderstanding about the type of anastomosis that was created . The anastomosis was intima - to - intima, with the vessels held together with circumferential ligatures over a specially designed metal ring . Kolesov did the first successful coronary bypass using a standard suture technique in 1964, and over the next five years he performed 33 sutured and mechanically stapled anastomoses in Leningrad (now St. Petersburg), USSR . </Li> <Li> René Favaloro, an Argentine surgeon, achieved a physiologic approach in the surgical management of coronary artery disease--the bypass grafting procedure--at the Cleveland Clinic in May 1967 . His new technique used a saphenous vein autograft to replace a stenotic segment of the right coronary artery . Later, he successfully used the saphenous vein as a bypassing channel, which has become the typical bypass graft technique we know today; in the U.S., this vessel is typically harvested endoscopically, using a technique known as endoscopic vessel harvesting (EVH). </Li> <Li> Soon Dudley Johnson extended the bypass to include left coronary arterial systems . </Li> <Li> In 1968, doctors Charles Bailey, Teruo Hirose and George Green used the internal mammary artery instead of the saphenous vein for the grafting . </Li> </Ul> <Li> The first coronary artery bypass surgery was performed in the United States on May 2, 1960, at the Albert Einstein College of Medicine - Bronx Municipal Hospital Center by a team led by Robert H.
