    ObjectiveTo determine the prevalence of concomitant aortic regurgitation (AR) in cardiac surgery and the outcomes of treatment options.MethodsBetween April 2004 and June 2018, 3289 patients underwent coronary artery bypass, mitral valve, or aortic aneurysm surgery without aortic stenosis. AR was graded none/trivial (score = 0), mild (score = 1+), or moderate (score = 2+). Patients with untreated 2+ AR were compared with those with 0 or 1+ AR, and to those with 2+ AR who had aortic valve surgery. Thirty-day and late survival, echocardiography, and clinical outcomes were compared using propensity score matching.ResultsOne hundred thirty-eight patients (4.2%) had 2+ AR; and 45 (33%) received aortic valve repair (n = 9) or replacement (n = 36) in the treated group and were compared with 2765 untreated patients with 0 AR and 386 patients with 1+ AR. Valve surgery was more common with anatomic leaflet abnormalities: bicuspid aortic valve (9% vs 0%; P < .01), rheumatic valve disease (16% vs 3%; P < .01), and calcification (47% vs 27%; P = .021). In unadjusted analysis, lower preoperative AR grade was associated with increased 10-year survival (P < .001). At year 10, progression to more-than-moderate AR among moderate AR patients was 2.6% and late intervention rate was 3.1%. In the untreated 2+ AR group, on last follow-up echocardiogram, 58% had improvement in AR, 41% remained 2+, and only 1% progressed to severe AR.ConclusionsAortic valve surgery in select patients with concomitant moderate AR can be added with minimal added risk, but untreated AR does not influence long-term survival after cardiac surgery and rarely required late intervention.Copyright © 2021 The American Association for Thoracic Surgery.
