Results of bicuspid aortic valve reconstruction
Abstract
Bicuspid Aortic Valve (BAV) is the most common congenital heart anomaly, often leading to aortic regurgitation (AR), stenosis, or aortopathy. While aortic valve replacement remains standard for stenosis, valve-sparing procedures for AR are underutilized despite promising results.
Methods: From 2018–2023, 30 BAV patients (28 males, mean age 26 ± 11.8 years) underwent aortic valve reconstruction. Mean AR grade was 2.7 ± 0.86; 43% had aortopathy (11 Yacoub remodeling, 1 David procedure, 1 supracoronary replacement). Annuloplasty was performed in 76% (16 external, 7 subcommissural), and 86% required leaflet/sinus interventions.
Results: Follow-up was 93.4% complete (median 15 months). Mortality was 3.3% (COVID-related). Two reoperations (6.9%) occurred for recurrent AR. Post-repair annulus diameter decreased to 23.9 ± 3.1 mm. Freedom from AR ≥ grade 2 was 81.5%; ≥ grade 3 was 96.3%.
Conclusion: BAV often requires combined aortic and valvular treatment. Reconstruction is safe with good mid-term outcomes, but proper patient selection and annuloplasty are critical. AR grade 2 at discharge and annulus dilation may predict recurrence, warranting further study. Root anatomy preservation is essential for durability.
Biography
Sergey Chetyrev, a cardiovascular surgeon and researcher specializing in valvular heart disease. Currently, I work as a postgraduate fellow at the Bakulev National Medical Research Center for Cardiovascular Surgery, one of Russia’s leading institutions in cardiac care. My journey in medicine has been driven by a passion for surgical innovation and a commitment to improving outcomes for patients with complex heart conditions. As a researcher, I have authored over 20 peer-reviewed publications in national and international journals, covering topics such as valve-sparing procedures, hemodynamic optimization, and long-term surgical outcomes.
