ObjectivesTo investigate the incidence of intravalvular leak after aortic valve replacement with the Inspiris Resilia valve.DesignThis study was a retrospective chart review.SettingThis study used data from a single tertiary care academic center.ParticipantsA total of 81 patient charts and echo images were reviewed.InterventionsAll patients underwent an aortic valve replacement using the Inspiris Resilia valve. Pediatric patients and patients receiving an aortic valve conduit were excluded.Measurements And Main ResultsTransesophageal echocardiography (TEE) images were reviewed independently by 2 echocardiographers for the incidence and severity of intravalvular leak after Inspiris Resilia valve placement. Outpatient follow-up imaging was then compared to intraoperative findings. Valve size and mean gradients were documented as well. Of the 81 TEEs that were reviewed, 56 (69.1%) were found to have a strut leak at the time of implantation. Among these 56 cases, 30 were classified as trace regurgitation, 21 as mild regurgitation, and 5 as moderate regurgitation. Only 1 case necessitated a return to cardiopulmonary bypass owing to persistent intravalvular leak. Follow-up transthoracic echocardiography reports were available for 50 of the patients with no persistent leaks.ConclusionsThis pattern of intravalvular leak is unique to the Inspiris Resilia valve and is commonly found in the intraoperative period. While many hypotheses exist for the origin of this leak, the exact mechanism is unclear. Given the high frequency of this postprocedure finding, it is essential that intraoperative echocardiographers be able to distinguish this clinically insignificant leak based on its origin, severity, and direction and to provide appropriate recommendations to our surgical colleagues.Copyright © 2024 Elsevier Inc.
