    Abstract:
    BACKGROUND: Outcomes of surgical intervention for severe tricuspid regurgitation related to Ebstein anomaly or tricuspid valve dysplasia in the neonatal period, particularly when associated with pulmonary atresia, are extremely poor. However, owing to emerging innovative surgical techniques, such as cone reconstruction, outcomes of tricuspid valve plasty in the neonatal period have gradually improved. METHODS: The study retrospectively reviewed the medical records of 12 neonates who were diagnosed with severe tricuspid regurgitation and pulmonary atresia related to Ebstein anomaly (n = 9) or isolated tricuspid valve dysplasia (n = 3) between 2000 and 2013. RESULTS: The first 6 patients underwent palliative therapy in anticipation of future functional single-ventricle palliation (Starnes operation). Biventricular repair was performed in the 6 patients born after 2012. As tricuspid valve plasty, cone reconstruction has been applied since 2013. Five patients underwent a Starnes operation, and 5 patients underwent biventricular repair, including 4 cone reconstructions. Four of the 5 patients who underwent a Starnes operation died in-hospital; the remaining patient underwent a Fontan operation at age 2 years. Three of the 5 patients who underwent biventricular repair survived. On echocardiogram, the 3 survivors who were treated with biventricular repair had a preoperative tricuspid regurgitation flow velocity greater than 3.0 m/s. CONCLUSIONS: Biventricular repair with cone reconstruction can be applied for severe tricuspid regurgitation due to neonatal Ebstein anomaly or tricuspid valve dysplasia with associated pulmonary atresia. A tricuspid regurgitation flow velocity greater than 3.0 m/s may be an indicator of successful biventricular repair.
