ABSTRACT
There is a wide range of heterogeneous lesions that can be defined as tricuspid dysplasia. In most severe cases, the leaflets are grossly dysplastic, the chordae tendinae are hypoplastic and, consequently, the degree of insufficiency will be high. At the other end of the spectrum, there are benign cases showing only mild thickening and limited malfunction. The latter cases are compatible with a virtually normal life.
