Key result
The modified Carpentier's technique for Ebstein's anomaly repair significantly reduced tricuspid regurgitation grade (from 3.72 to 1.56, p<0.01) and improved NYHA class (from 2.53 to 1.14, p<0.01).

Does the modified Carpentier's technique improve tricuspid regurgitation and NYHA functional class in patients with Ebstein's anomaly?
The modified Carpentier's technique for Ebstein's anomaly repair significantly improves tricuspid regurgitation and NYHA functional class with excellent long-term survival and freedom from reoperation.
May support modified Carpentier repair in Ebstein's anomaly; hypothesis-generating and requires prospective validation before practice change.
OBJECTIVES: This retrospective study assesses the outcomes of a modified Carpentier's technique for Ebstein's anomaly repair in respect to functional and anatomical recovery of the right ventricle and tricuspid valve. PATIENTS AND METHODS: From August 2005 to December 2010, 52 patients with Ebstein's anomaly were operated in Hanoi Heart Hospital, Vietnam using the modified Carpentier's technique: (1) extensive mobilization of the tricuspid leaflet by detachment of the posterior, septal, and the adjacent part of the anterior leaflet; (2) longitudinal plication of the atrialized chamber and the right atrium to reconstruct the right ventricle and reduce the size of the dilated right atrium; (3) relocation of the anterior, posterior, and septal leaflets to the normal tricuspid annulus; and (4) tricuspid annuloplasty. RESULTS: Mean age was 20 years (3-49 years). Tricuspid regurgitation (in four-grade scale) was reduced from 3.72 ± 0.48 to 1.56 ± 0.48 (p < 0.01) and NYHA functional class was improved from 2.53 ± 0.53 to 1.14 ± 0.35 (p < 0.01). There was one hospital death (1, 95%) due to postoperative severe bleeding. There was no long-term mortality or reoperation after 42.4 months (17-81 months) follow-up. CONCLUSION: Satisfactory outcomes can be achieved with complete repair of Ebstein's anomaly using the modified Carpentier's technique.

Hiền et al. (2014) conducted an observational in Ebstein's anomaly (n=52). Modified Carpentier's technique was evaluated on Tricuspid regurgitation grade and NYHA functional class (p=< 0.01). The modified Carpentier's technique for Ebstein's anomaly repair significantly reduced tricuspid regurgitation grade (from 3.72 to 1.56, p<0.01) and improved NYHA class (from 2.53 to 1.14, p<0.01).
