COMPARISON OF SHORT- AND LONG-TERM RESULTS OF VARIOUS TECHNIQUES OF TRICUSPID VALVE REPAIR IN EBSTEIN’S ANOMALY
Introduction. There are different options in surgical treatment of Ebstein's anomaly, including tricuspid valve repair, replacement or cone repair of tricuspid valve. The aim of the study is to compere short and long-term results of different methods of surgical treatment of Ebstein's anomaly. Material and methods. From 1992 to 2017 year, 42 consecutive patients underwent surgical treatment of Ebstein's anomaly in the Samara Regional Cardiac Center and Saint Petersburg Children's Hospital № 1. Twenty one patients had cone repair of tricuspid valve (group 1) and 21 patients had conventional tricuspid valve repair or replacement (group 2). Results. Only one early death occurred in group 2, surgical mortality in this group is 4.7%. The average follow-up period is 1.4 ±1.1 years in group 1 and 10.8 ± 5.8 years in group 2 ( p = 0.0003). There were no deaths in either group during follow up. One patient (4.7%) in group 1 and 8 (38%) patients in group 2 required reoperation during follow-up period. Conclusion. Cone repair of tricuspid valve can be performed with good short-term results. The incidence of reoperation is high in long-term follow up period, especially following conventional tricuspid valve repair or replacement.
