Abstract
OBJECTIVES: Congenital tricuspid valve dysplasia (TVD) is a rare cardiac disease, often discussed in the same way as Ebstein's anomaly. Though the morphology of TVD is different, the clinical appearance is similar. The indication for surgical treatment depends on the morphology of the tricuspid valve (TV) and the clinical presentation. METHODS: We reviewed all patients below 18 years of age who underwent TV repair between 2005 and 2019 and identified 9 with a TVD. The diagnosis was verified with the operative notes and patients were excluded if the septal leaflet was displaced as in Ebstein's anomaly. The aim of the study was to describe the morphology of the TV and analyse the surgical possibilities and their results. RESULTS: The median age at surgery was 2.3 years (5 days to 14 years), 3 patients were neonates with a duct-dependent pulmonary circulation. Morphology of the TV showed a tethering of at least 1 leaflet in all patients, a restrictive septal leaflet in 8, a large anterior leaflet in 7 and a small posterior leaflet in 4. Surgical techniques included an annuloplasty in 7 patients, a leaflet procedure in 6 patients, an edge-toedge stitch in 5 patients and a primary Starnes procedure in 1 neonate. During a median follow-up time of 2.8 years (5 months to 15 years), 1 valve replacement and 1 conversion to univentricular palliation were necessary. CONCLUSIONS: Unequal leaflet size and tethering are the most common features of TVD. A variety of surgical techniques is available to achieve good results beyond the neonatal period.
