Validation of a new score for the assessment of mitral stenosis using real-time three-dimensional echocardiography.

Methods: A two-staged study was conducted. In the first stage, the feasibility of a new RT3DE score was assessed in 17 patients with MS.

Unusual bileaflet tricuspid valve by real time three-dimensional echocardiography.

The right atrioventricular valve is formed by three leaflets as described by the classic anatomic studies. Two-dimensional transthoracic echocardiography (2DE) shows the tricuspid valve (TV) in its long axis. However, short-axis views of the TV leaflets are not generally obtained and therefore distinction between leaflets by 2DE is difficult.
