Modified carpentier's technique for Ebstein's anomaly repair.

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.
