I am a post-doctoral research fellow and an incoming pediatric resident at Cleveland Clinic. I recieved my MD degree from the American University of Beirut (AUB) in 2023. I am interested in pediatric cardiology and have a special interest in the congnenital abnormalities of the aorta.

Description
Objective: Aortic valve repair techniques are still evolving with better understanding of aortic root and leaflet imaging. This study seeks to present results of an additional new technique in aortic valve repair. The technique entails remodeling of the leaflet by peeling off the fibrous tissue of thickened leaflets (on the ventricular side of the aortic valve along with thinning and plication of the central region of the leaflets). Other repair techniques are added to complete the repair.
Methods: A retrospective chart analysis of 10 patients that underwent aortic valve remodeling for aortic regurgitation and received advanced imaging pre-operative assessment from January 2022 to November 2023. Institutional review board approval was obtained under expedited review for retrospective studies.
Results: All patients with a wide range of congenital pathologies, underwent leaflet remodeling, five patients underwent additional valve-sparing root replacement and four had subaortic annuloplasty. Nine patients had moderate or severe aortic insufficiency at the time of presentation. Mean clinical follow-up was 166 days (range: 8, 538). At follow-up, 6 patients did not have aortic regurgitation on echocardiogram and the remaining four had mild regurgitation. All patients assessed for LVEF at follow-up had their EF>50%. None of the patients required re-operation.
Conclusions: Leaflet remodeling expands leaflet dimensions by freeing tethered portions and improves mobility. This additional technique will preserve more valves from replacement. However, further follow up is needed.

Presentation Duration
PODS will be on display in the exhibit hall for the duration of the meeting during exhibit hall hours. PODS will also be available for viewing on the meeting website. There is no formal presentation associated with your POD, but we encourage you to visit the PODS area during breaks to connect with those viewing.
