[III-JCKAP6-2-5] Long-Term Outcomes of Modified Cone Reconstruction for Ebstein's Anomaly in a Single Center
キーワード：Ebstein anomaly, Tricuspid regurgitation, Cone reconstruction
Background and Objective: We aimed to investigate long-term clinical and echocardiographic outcomes, including tricuspid valve durability, after modified cone reconstruction in patients with Ebstein's anomaly. Methods: This was a retrospective analysis of all patients who underwent modified cone reconstruction for Ebstein's anomaly at a single tertiary center between January 2005 and June 2023.Results: A total of 35 patients underwent modified cone reconstruction for Ebstein's anomaly; the mean age was 27.1 years (range, 0.01~63.7). There were five patients (14.3%) with Carpentier type A, ten patients (28.5%) with Carpentier type B, eighteen patients with Carpentier type C (51.4%), and two patient with Carpentier type D (5.7%). Mean cardiopulmonary bypass time and aortic cross clamp time were 122.9 minutes and 88.1 minutes, respectively. Mean hospital day was 11.6 days. There was no early or late mortality. During follow-up, one patient (2.8%) underwent reoperation for tricuspid regurgitation due to leaflet perforation. Median follow-up duration was 5.0 years (range (0.2~13.1)Conclusions: Ebstein's anomaly can be repaired by modified cone reconstruction with low mortality, morbidity, and good tricuspid valve durability.
