A NEED FOR LESS-INVASIVE CORONARY BYPASS SURGERYIn the 1990s and early 2000s, attempts at performing lessinvasive coronary artery bypass grafting (CABG) were largely restricted to the minimally invasive direct coronary artery bypass operation, itself a variation of the first CABG operation performed-in 1964 and through a thoracotomy-by Kolesov and Potashov. 1 With the exception of multiple anterior target coronary vessels and other rare favorable combinations, multivessel bypass grafting through a nonsternotomy incision was not considered feasible until a large consecutive patient series was published in 2009. 2 These minimally invasive (MICS) CABG data became a catalyst for the adoption, over the ensuing decade, of this operation at other expert centers in America, Asia, Europe, and Oceania. Nowadays, it is estimated that thousands of MICS CABGs are performed every year. Nevertheless, multivessel MICS CABG remains a technically challenging operation performed only at select centers. Complete ease of the surgeon and team at off-pump coronary artery bypass (OPCAB) represents 1 prerequisite, after which surgeons should initiate single-vessel MICS CABG to the left anterior descending artery, performed either conventionally or with robotic assistance. Numerous training programs and peer-to-peer options exist for surgeons and teams who wish to learn and develop MICS CABG. The outcomes of this operation have also been validated by several groups, and data pertaining to its safety, feasibility, adoptability, angiographic patency of grafts and, as of recently, long-term durability, are now available. 3-6 A randomized clinical trial comparing multivessel surgical revascularization by MICS CABG versus regular From the
