Individualized quantified tricuspid valve annuloplasty for treating Ebstein anomaly.

BACKGROUND AND AIM OF THE STUDY

The study aim was to evaluate whether individualized quantified selective tricuspid valve annuloplasty would be suitable for the treatment of Ebstein anomaly.

METHODS

Between March 1999 and February 2011, a total of 23 patients with Ebstein anomaly underwent individualized quantified selective tricuspid valve annuloplasty at the authors' institution. The annulus was reconstructed according to each patient's individual anatomic characteristics of their tricuspid valve. Echocardiography was used to assess the changes of tricuspid valve regurgitation and heart function perioperatively and also during the follow up period.

RESULTS

There was no hospital mortality. One patient died suddenly at 41 months after surgery, and two patients were lost to follow up; the remaining patients are still alive. During the follow up, tricuspid valve regurgitation and cardiac function were improved in all patients postoperatively, with no acquired tricuspid stenosis.

CONCLUSION

The study results and analysis of follow up data suggested that an '...individualized quantified selective concept and technique of tricuspid valve reconstruction' is reasonable, suitable, and practical in the treatment of Ebstein anomaly.
