“…Radial artery graft patency is best when used to graft a left-sided coronary artery with high grade stenosis and worst when utilized on the lower pressure right heart. The gastroepiploic artery is most often used to bypass the right coronary artery or its branches, but it is prone to spasm [ 31 ]. The 1-, 5-, and 10-year patency rates of the gastroepiploic artery are reportedly 91%, 80%, and 62%, respectively [ 32 ].…”

The development of the heart-lung machine ushered in the era of modern cardiac surgery. Coronary artery bypass graft surgery (CABG) remains the most common operation performed by cardiac surgeons today. From its infancy in the 1950s till today, CABG has undergone many developments both technically and clinically. Improvements in intraoperative technique and perioperative care have led to CABG being offered to a more broad patient profile with less complications and adverse events. Our review outlines the rich history and promising future of myocardial revascularization.

Introduction Coronary artery bypass grafting (CABG) is one of the most commonly performed operations with approximately 200 000 procedures performed annually in the United States of America and an incidence of 62 per 200 000 inhabitants in Western Europe. 1 It has evolved over the past century from a high-risk procedure to a relatively safe one with a current mortality rate of 1%-2% in elective patients. 2 Nonetheless, it is still a highly complex surgery and has been associated with a number of complications. The complications from this major surgery can be classified in various ways; some are catastrophic, such as death and stroke, while others can be self-limiting without any long-term residual effects, such as atelectasis, lower respiratory infection, or transient acute kidney injury. 2,3 CABG can be considered as a large operation incorporating many smaller operations. There may be variations in these smaller operations that can have both advantages and disadvantages. However, the end goal is to bypass a blocked or narrow coronary artery by anastomosis of a vessel conduit. 3 This may be done with or without cardio-pulmonary bypass, with arterial or venous grafts, and with open or endoscopic harvesting of conduits. The overall risk of this operation is determined by the Euroscore, which is a statistical determination of risk using logistic regression. 4,5 It is determined by patient-related factors (age, gender, renal impairment, peripheral vascular disease, mobility, previous cardiac surgery, chronic lung disease, active endocarditis, critical pre-operative state, insulin dependent diabetes), cardiac-related factors (NYHA dyspnea classification, CCS angina classification, left ventricular function, recent myocardial infarction, and pulmonary hypertension) and operation factors (urgency, weight of intervention, and involvement of thoracic aorta). 5 For the purposes of valid patient consent, it is considered mandatory to discuss the risk of death, peri-operative myocardial infarction, stroke, and sternal wound infection. 6 The general complications of CABG surgery are briefly discussed below followed by a discussion of the specific complications associated with cardiopulmonary bypass and graft patency. Extent of Complications Complications can be broadly divided into catastrophic events, such as death and stroke, or less serious complications, such as pulmonary, renal, or sternal wound complications. Death Mortality following CABG is reported to be between 1%-2% for elective procedures; however, it can be confounded by many factors including the urgency of the case, previous acute myocardial events, the presence of multiple comorbidities such as diabetes or chronic renal failure, or poor coronary vessels that are not amenable for grafting. 4-6 Stroke Post-operative stroke has an incidence of 1.4% to 3.8%. 2 The risk factors for this complication include increased age,

Abstract: Pre-operative angiography predicts graft patency in RGEA, whereas the flow pattern in SVG is significantly less influenced by quantitative angiographic parameters.
