Dynamics of the tricuspid valve annulus in normal and dilated right hearts: a three-dimensional transoesophageal echocardiography study

Abstract

Three-dimensional TOE allows us to examine the TVA in great detail. In patients with DRH, the TVA dilates in a SL direction, resulting in a more circular orifice. The dynamic changes of the TVA are lost in patients with DRH, potentially contributing to functional tricuspid regurgitation.
