Cone reconstruction in Ebstein's anomaly repair: early and long-term results.

Background: The main Ebstein anomaly (EA) repairs are based on the monocusp reconstruction of the tricuspid valve and are limited by the frequent need for replacement or the high recurrence of valve regurgitation.

Objective: To evaluate the feasibility and effects of anatomical repair of Ebstein's anomaly using the cone reconstruction technique on patients' clinical evaluation, tricuspid valve function and right ventricular morphology.

Methods: We compared the clinical, echocardiographic and radiological data of 52 consecutive patients, with a mean age of 18.
