ObjectiveTo analyze the Ebstein anomaly's reoperative strategy and mid- to long-term results.MethodsWe retrospectively reviewed the clinical data of 23 patients who diagnosed with Ebstein anomaly and underwent reoperation for tricuspid valve insufficiency between July 2002 and July 2017 in Fuwai Hospital. There were 9 (39.1%) males and 14 (60.9%) females, with a median age of 28.0 (19.0, 45.0) years.ResultsAmong the 23 patients, 8 (34.8%) underwent tricuspid valvuloplasty and 15 (65.2%) underwent tricuspid valve replacement. The rate of valvuloplasty was 16.7% before 2012, and 54.5% after 2012 (P=0.089) as Cone reconstruction procedure was used. In the valvuloplasty cohort, 3 (37.5%) patients were treated with Danielson or Carpentier technique, and 5 (62.5%) patients were treated with Cone reconstruction procedure. There was no operation-related death. Early complications occurred in 3 (37.5%) patients. The median follow-up was 6.9 years (range, 3.0-15.1 years), and no adverse cardiac events occurred. In the patients with valve replacement, 7 (46.7%) received mechanical prosthesis and 8 (53.3%) received bio-prosthesis. There was no operation-related death. And early complications were observed in 3 (20.0%) patients. The median follow-up was 6.5 years (range, 2.5-15.3 years). One (6.3%) patient died and 4 (26.7%) had long-term complications during the follow-up period.ConclusionThe mid- to long-term outcomes are convincing in patients who undergo the second operation due to recurrent tricuspid regurgitation of Ebstein anomaly. A low incidence of reoperation is observed. Cone reconstruction procedure provides possibilities of second tricuspid valvuloplasty, and this technique can reduce the rate of tricuspid valve replacement in the second operation. Tricuspid valve replacement is still an alternative method for the treatment of recurrent tricuspid regurgitation in patients with Ebstein anomaly. The bioprosthetic prosthesis may be a better choice than mechanical prosthesis.
