Unstented semilunar homograft replacement of tricuspid valve in Ebsteinʹs malformation

Tricuspid valve pathology in Ebsteinʹs malformation requires replacement when it is not possible to repair or reconstruct this valve. In smaller children, in whom the right-sided atrioventricular valve is severely dysplastic and right ventricular volume is prohibitive, prosthetic replacement is not always possible. We report here on 3 patients who underwent stentless semilunar homograft replacement (top-hat procedure) of tricuspid valve for Ebsteinʹs anomaly with good short-term outcome. This provides an attractive alternative in the management of a certain difficult subset of patients, avoids long term anticoagulation and probably is more durable.
