Burden of Tricuspid Regurgitation in Patients Undergoing Coronary Artery Bypass Grafting

BackgroundTricuspid regurgitation (TR) is associated with poor outcomes after cardiac surgery. Guidelines recommend correction of severe TR in patients undergoing left-sided valve surgery but not coronary artery bypass graft (CABG). We sought to evaluate impact on CABG.MethodsAll (n = 28,027) CABG The Society Thoracic Surgeons (STS) regional database (2011 2018) were stratified by severity. Primary included major morbidity or mortality, which compared using univariate analysis.ResultsOf CABG, 4837 (17%) had mild, 800 (3%) moderate, and 81 (0.29%) TR. Increased severity was higher rate preoperative heart failure (none 5162 [23.4%] vs mild 1697 [35%] moderate 427 [53%] 54 [67%], P < .001] STS predicted risk mortality (1.0 [0.6 1.9) 1.4 [0.8 2.9] 2.8 [1.4 5.4] 6.2 [2.2 11.4], .001).
