Abstract
Coronary endarterectomy is an old surgical procedure against coronary artery disease which was first described by Baily et al. in 1957. In spite of the first adverse effects, several recent publications have demonstrated that coronary endarterectomy (CE) with coronary artery bypass grafting (CABG) can be done safely with appropriate mortality and morbidity. The main objective of CABG is complete revascularization of coronary vessels and, particularly, left internal mammary artery to left anterior descending artery (LIMA-LAD) anastomosis, Since; patent LIMA-LAD is the single most significant determinant for long-term and eventfree survival. A best evidence topic in cardiac surgery was written according to a structured protocol. The problem was whether LAD artery open endarterectomy (open-CE) with CABG compares favorably with LAD artery closed endarterectomy (closed-CE) with CABG in the myocardial revascularization of patients presenting with diffuse coronary artery disease (DCAD). The purpose of this review is just to determine the safety and feasibility of CE in general and open-CE versus closed-CE particularly. The last search date was December 2019 and the search period was from 1992 till 2019. Open-CE with CABG may carry a lower early mortality rate (range from 2.9% to 8.8%) than closed-CE with CABG (range from 6.8% to 10.9%) and CE + CABG has a significantly higher risk of death than isolated CABG. Internal thoracic artery (ITA) use may enhance mortality, while the saphenous vein (SV) conduit or two CE vessels may worsen the clinical outcome. The main complication of CE can be found in post-operative atrial fibrillation (AF), in our review; the rate ranged from 9% to 29%. Another devastating complication is postoperative myocardial infarction (MI) with a range of 0% to 13.9%.
