Abstract: Background:The incidence of Ebstein's anomaly is extremely low,and except for the Mayo Clinic,no cardiac center has reported on a sufficient number of patients.The aim of our study was to report the outcomes of Ebstein's anomaly patients treated with tricuspid valvuloplasty (TVP) or tricuspid valve replacement (TVR).Methods:TVP or TV R was performed in 245 patients from July 2006 to April 2016.We reviewed patients' records and contacted patients via outpatient service and over the telephone.Results:The mean follow-up time was 43.6 ± 32.6 months,and 224 (91.4%) patients underwent follow-up.The mean operative age was 31.2 ± 15.7 years.TVR was performed in 23 patients,and TVP was performed in 201 patients.The 30-day mortality rate was 1.3%,and the overall survival rate was 97.9% at 5 and l0 years.The early mortality rate of the TVP group was lower than that of the TVR group (0.5% vs.8.7%,P =0.028),and the overall mortality rate of the TVP group was lower than that of the TVR group,without statistical significance (1.0% vs.8.7%).After propensity score matching,the rates of mortality and New York Heart Association class ≥Ⅲ were lower in the TVP group than those in the TVR group without statistical significance.Seven patients with Type B Wolff-Parkinson-White (WPW) syndrome underwent one-stage surgery,and arrhythmias disappeared.Six patients suffered from episodes of left ventricular outflow tract obstruction (LVOTO) during surgery.Severe LVOTO could be treated with reoperation of the atrialized right ventricle.Conclusions:Ebstein's anomaly patients treated with TVP or TVR can experience optimal outcomes with midterm follow-up.However,TVP should be the first-choice treatment.Optimal outcomes can be obtained from one-stage operation in patients with Type B WPW syndrome.Severe LVOTO during surgery might be related to improper operation of the atrialized right ventricle.
