In a research letter published in the Journal of the American College of Cardiology, a group of researchers led by Dr. Marc Ruel of the University of Ottawa Heart Institute (UOHI) conclude that minimally invasive coronary artery bypass grafting (MICS CABG) has “favourable long-term outcomes” for patients.
Their claim is based on a longitudinal follow-up study of 510 consecutive patients who underwent MICS CABG from September 2005 to December 2020 at the UOHI.
The advantage for patients: MICS CABG allows the bypass surgery to be done through a small incision between the ribs rather than through the larger chest opening required in standard CABG surgery.
“The present data indicate, for the first time in a large patient cohort with complete longitudinal follow-up, that the late results of MICS CABG can yield favourable long-term outcomes,” writes Dr. Marc Ruel, head of the Division of Cardiac Surgery at the UOHI. “This confirms not only the short-term safety and durability of MICS CABG in expert hands, but also its long-term durability.”
The MIST (Minimally Invasive coronary surgery compared to STernotomy coronary artery bypass grafting) trial is currently ongoing and will provide further evidence as to whether MICS CABG provides earlier recovery and equivalent or better long-term outcomes compared with sternotomy CABG.
