"Leafletization" of atrialized ventricular septum endocardium in Ebstein's anomaly

Ann Thorac Surg. 2021 Mar 2:S0003-4975(21)00360-X. doi: 10.1016/j.athoracsur.2020.12.093. Online ahead of print.ABSTRACTThis case presentation about a 73-year-old man introduces a unique tricuspid valve repair with "endocardium leafletization" for Ebstein's anomaly. In this procedure, atrialized portion of the right ventricular endocardium was delaminated starting from the level of the true tricuspid annulus to create neo-leaflet in continuity with the displaced true leaflet. The obtained neo-leaflet was then anchored to the true tricuspid annulus. Preoperative severe tricuspid regurgitation was effectively controlled with preserving sufficient leaflet mobility. This procedure can be one of useful options for a certain lesion of Ebstein's anomaly, which aims to avoid excessive leaflet rotation and restore functional valve apparatus.PMID:33667458 | DOI:10.1016/j.athoracsur.2020.12.093
