Current information as to the mechanism which causes malcoaptation of the tricuspid leaflets and leads to regurgitation is lacking. This study investigated the effect isolated and combined annular dilatation and PM displacement on valve mechanics. 3D echocardiography was used to quantify the changes in valve mechanics in relation to changes in tricuspid regurgitation.
