ABSTRACT: Background: Aortic neo-cuspidization (AVNeo) procedure has been adopted by limited
centers with the publication of the mid-long term successful results. The aim of this study was to present initial experience of the
AVNeo procedure of a single center. Methods: The medical records of 24 patients who underwent AVNeo with or without
concomitant cardiac surgery between February 2019 and February 2021 at our
tertiary hospital were scanned retrospectively. Results: The mean age of
patients was aged 58.21 ± 13.14 years and 16
(66.7%) of them were men. 16 patients were operated on for aortic stenosis
(66.67%). Morphology of the aortic valve was tricuspid in 21 (87.5%) and bicuspid in 3 (12.5%) of the patients. Additional
cardicac surgery was performed in 13 (54.17%) patients. No patients
needed reoperation for bleeding, pacemaker
implantations, conversion to classical prosthetic aortic valve replacement, or infective endocarditis. Two patients died due to non-cardiac reasons. Preoperative peak and mean aortic valve pressures improved
significantly at 1st and 6th months (Preop: 89.06 ± 21.88 mmHg and
56.38 ± 15.09 mmHg 1st month:
22.00 ± 3.93 mmHg and 8.73 ± 2.60 mmHg, 6th month: 18.13 ±
3.02 mmHg and 6.93 ± 1.83 mmHg). Conclusion: In conclusion, the AVNeo procedure is
a feasible technique for aortic valve pathologies, with the advantages
of avoiding anticoagulants and the applicability of concomitant surgical procedures. Although this procedure requires
meticulous experience, results similar to the available published
literature can be obtained and reproducible even during learning curve when
technical steps are strictly followed.
