Biventricular remodeling and function after Cone repair of Ebstein Anomaly: A review.

ABSTRACT: The Cone reconstruction is the prevailing repair strategy for Ebstein anomaly (EA), providing near-anatomical restoration of the tricuspid valve (TV) and reliable reduction of tricuspid regurgitation (TR). Most of the risk of Cone repair is seen in the early postoperative period from dehiscence, with very low rates of mortality and reintervention thereafter. By correcting TV dysfunction and abnormal right ventricle (RV) geometry, ventricular reverse remodeling has been demonstrated through decreased right atrial and atrialized RV size, along with improved antegrade pulmonary flow and consequent left ventricular filling. Early postoperative RV dysfunction is common due to increased afterload upon addressing TR, with suggestion of delayed recovery. Cone repair augments left ventricular prelo
