Three-dimensional transesophageal echocardiography provides incremental value over 2D imaging in accurately diagnosing rare congenital anomalies such as a bileaflet tricuspid valve.

May offer incremental diagnostic value for rare valve anomalies; hypothesis-generating and warrants prospective validation.
Detailed assessment of the tricuspid valve using two-dimensional echocardiography is always challenging, as only two of three leaflets can be seen at a time. Three-dimensional echocardiography can provide the enface view of the tricuspid valve that allows simultaneous visualization of all of the three leaflets. In a 42-year-old male patient scheduled for pulmonary endarterectomy, 3DTEE showed that the tricuspid valve is bileaflet, with one septal and another lateral leaflet. There were two commissures, one of them is anteriorly positioned and the other one is posterior. Our findings were confirmed intra-operatively by direct surgical visualization of the tricuspid valve.
