Abstract:
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. Real time three-dimensional echocardiography (RT3DE) overcomes this limitation of 2DE and facilitates obtaining short axis view (enface view) of the TV. In the current case study, en face view of the TV obtained by RT3DE was found to be formed of only two leaflets with two commissures. The surgical findings were consistent with that of RT3DE.
