The Modified Surgical Repair Techniqe Correct Ebstein's Anomaly

Objective To review retrospectively the experience of surgical treatment of with a modified carpentier repair technique.Methods From March 1998 to December 2006,the modified Carpentier repair technique was used in 18 patients(6male,12 female);age range 6 to 38 years(mean 20 years)with Ebstein anomaly(research group).They were classified into Carpentier:2 type A,11 type B,and 5 type C,all with serious regurgitation of the tricuspid valve.Operative techniques were suture longitudinal plication of the atrialized right ventricle and adjacent right atrium;shortening tricuspid annulus,repositioning of the anterior and posterior leaflets to cover the orifice area at the normal level,and remodeling and reinforcement of the tricuspid annulus;transection and reimplantation its or their papillary muscle;simultaneous correction other congenital malformation.As control group,other surgical procedures(including Hardy procedure, Denielson procedure,and Carpentier procedure)were used in 10 patients(control group).The follow-up data and results(tricuspid regurgitation,cardio-thoracic ration)of the two groups were studied and compared.Result There was no operative mortality in research group.Correction of tricuspid regurgitation were improved significantly in research group;there was no difference in cardio-thoracic ration between research group with control group.Conclusion The modified Carpentier repair technique for Ebstein's anomaly can im- proved significantly in research group than those in control group(P＜0.05).
