Advantages and disadvantages of total arterial coronary artery bypass graft as compared to venous coronary artery bypass graft

Abstract

Considering the plethora of literature about surgical revascularization, this review aims to discuss the most recent studies about the effects of total arterial coronary artery bypass graft (TACABG) compared with CABG that involves venous graft (VCABG) in patients with multivessel coronary artery disease. Patients were sampled from published papers that studied various aspects involving TACABG or VCABG. Resulting samples were used to compare the complexity and 5 years’ outcomes of TACABG to VCABG in the revascularization of coronary arteries. TACABG provides a better prognosis with average all-cause mortality within 5 years of 5.35% as compared to VACABG with average of all-cause mortality within 5 years of 9.1%. Furthermore, assumption of deep sternal wound infection from TACABG, especially when bilateral internal thoracic arteries were used, is very technique-dependent, as reports have been showing that the rate of such infection to occur is less than 1%. TACABG was concluded to wield a better prognosis within both short- and long- terms, although more research need to be done to prove its use in left main disease.
