“…Surgical correction of Ebstein's disease by a prosthetic valve replacement was first reported in 1963 and has yielded poor results; several modifications of valve repair techniques were introduced to create a monocusp valve and commissuroplasty or annuloplasty to restore competence of the tricuspid valve. 2,11,12,13 Danielson et al performed horizontal plication of the "atrialized" portion of the right ventricle, and right atrial reduction, while Chauvaud and Quaegebeur performed longitudinal plication for restoring the geometry and compliance of the right ventricle in addition to valvuloplasty. 3,14 The important component of repair in Ebstein's disease is a creation of a monocusp valve, generally with a large anterior tricuspid leaflet either by a single or multiple stitch technique, commissuroplasty, with or without plication of the "atrialized" right ventricle.…”
