In this cohort study of 49 404 patients, compared with the coronary artery bypass with at least 1 arterial and 1 saphenous venous graft, total arterial revascularization was associated with improved long-term freedom from major adverse cardiac and cerebrovascular events, death, and myocardial infarction.

It implies that total arterial revascularization may be the procedure of choice for patients with reasonable life expectancy requiring coronary artery bypass grafting.

In this large, population-based, multicenter study evaluating
the long-term outcomes of TAR vs non-TAR, researchers observed
(1) the overall prevalence of TAR in the province of Ontario in
Canada was low (2433 [4.9%]);
(2) patients undergoing TAR were younger and healthier compared with non-TAR patients.
(3) after PSM, in-hospital outcomes were excellent and
equivalent between techniques;
(4) TAR was associated with improved long-term freedom from MACCE, survival, and cumulative incidence of MI; and
(5) the TAR benefit was more prominent as the number of SVGs increased in the non-TAR group.

Of 49 404 individuals with primary isolated CABG, 2433 (4.9%) received TAR, with the total number of bypasses being 2, 3, and 4 or more vessels in 1521 (62.5%), 865 (35.6%), and 47 individuals (1.9%), respectively. Total arterial revascularization was associated with improved long-term freedom from major adverse cardiac and cerebrovascular events, death, and myocardial infarction and may be the procedure of choice for patients with reasonable life expectancy requiring CABG.
