Da Silva's cone repair for Ebstein's anomaly: effect on right ventricular size and function.

Objectives: Da Silva's cone repair is a novel technique for surgical reconstruction of the tricuspid valve and the right ventricle (RV) in Ebstein's anomaly. The technique consists of extensive leaflet mobilization, longitudinal plication of the atrialized ventricle and cone-shaped reconstruction of the tricuspid valve, allowing for leaflet-to-leaflet coaptation. We evaluated the influence of Da Silva's cone repair on tricuspid competency, right ventricular size and function.
