About Video

This video clip showing three-dimensional (3D) transthoracic echocardiographic assessment of tricuspid valve regurgitation. This video shows optimal visualization of the tricuspid valve (TV) regurgitation jet and the vena contracta (arrowhead) acquired using the apical four-chamber view. This was done by posteroanterior cropping of 3D data set. The data set was cropped from top to the level of the vena contracta, it was then tilted en face and the previously cropped posteroanterior tissue data added back. Subsequently, the maximum size of the banana-shaped TV regurgitation vena contracta was planimetered. (AS: Atrial septum; RA: Right atrium; RV: Right ventricle; VS: Ventricular septum).
