Multiple Arterial Bypass Grafts Are Superior to Single Ones

This propensity-matched registry analysis demonstrates a medium-term survival advantage with MAGs.

Despite the established benefit of left internal thoracic artery (ITA) grafts to the left anterior descending coronary artery during coronary artery bypass grafting (CABG) surgery, bilateral ITA or multiple arterial grafts (MAGs) have not been associated with a survival advantage compared with single arterial grafts (SAGs) in randomized trials. To learn more, researchers conducted an observational analysis using data from the New York Cardiac Surgery Reporting System on 63,402 CABG surgeries performed between 2005 and 2014.

The researchers focused on 10,828 propensity-matched pairs of MAG and SAG patients; postdischarge information was obtained from state databases.

At 1 year, MAG and SAG had similar mortality, but MAG patients had a higher r…
