- Abstract
Background: Whether patients with moderate left atrioventricular valve regurgitation (LAVVR) after surgical repair of complete atrioventricular septal defect (CAVSD) should be observed or undergo reoperation remains unclear., Methods: Moderate LAVVR was diagnosed in 87 of 220 patients who underwent CAVSD repair: 47 during the initial hospital stay and 40 after a median of 7 months (interquartile range, 2-18 months) after the initial operation., Results: Of these 87 patients who had moderate LAVVR, 15 died, for an overall mortality of 17%. The regurgitation became severe in 39 patients (45%) within a median of 2 months (interquartile range, 1-7 months) leading to 33 reoperations and 10 deaths. In 23 of 87 patients (26%), regurgitation remained at a moderate level over a median follow-up period of 8 months (interquartile range, 1-48 months). In 25 of 87 patients (29%), the regurgitation decreased to mild after a median of 9 months (interquartile range, 5-19 months). The only independent risk factor for increased severity of regurgitation and reoperation was the echocardiographic appearance of the jet centered around the cleft rather than central at the time of diagnosis of moderate regurgitation (odds ratio, 3.5; 95% CI, 1.5-9.0; P = .007)., Conclusions: Moderate LAVVR after CAVSD repair is often linked to death and reoperation, but regurgitation remains stable in one-quarter of patients and improves in one-third. The deterioration usually occurs within the first year after surgery. The initial observation of patients with residual or new moderate regurgitation for up to 1 year or until further deterioration seems reasonable, as long as the regurgitation is centrally located., Competing Interests: Disclosures The authors have no conflicts of interest to disclose., (Copyright © 2024 The Society of Thoracic Surgeons.
