[MSB-30] Clinical Outcomes of Bicuspid Aortic Valve Pathologies Treated with Tricuspidization Using the Ozaki Procedure
Year: 2024
Type: article
Study design: Observational Study
Abstract: Objective: The data of 44 patients (32 males, 12 females; mean age: 51.47±15.18 years) diagnosed with BAV who underwent tricuspidization with the aortic valve neocuspidization technique between February 2019 and July 2024 were retrospectively analyzed. Results: Additional surgical procedures were performed on 21 (47.72%) patients with BAV morphology. Echocardiographic measurements showed a significant reduction in preoperative peak and mean aortic valve pressures at one and 12 months. In patients who underwent simultaneous surgical procedures, the mean aortic cross-clamp time was 111±29.7 min, and the mean cardiopulmonary bypass time was 153±43.9 min. For isolated BAV defects, the mean aortic cross-clamp and cardiopulmonary bypass times were 89.9 ±19.5 and respectively. During the follow-up period, no patient required mechanical aortic valve replacement. One patient required pacemaker implantation on the seventh postoperative day due to the development of a third-degree atrioventricular block. In one patient, an ischemic cerebrovascular event occurred in the early postoperative period. Discussion: Although aortic valve neocuspidization requires experience, the application of standardized procedures allows for successful outcomes in BAV defects through the tricuspidization procedure. The tricuspidization procedure provides a more physiological structure and excellent hemodynamic performance of the aortic valve.
