[Congenital isolated tricuspid insufficiency in an elderly woman].

Isolated congenital tricuspid insufficiency due to primary malformation of the tricuspid valve is rare. The patient was a 70-years-old woman complaining of exertional dyspnea. Cardiac echo-sonography and catheterization showed severe TR with no other cardiac abnormality. At surgery, the anterior leaflet of the tricuspid valve was hypoplastic and attached to the right ventricle with shortened chorda. Tricuspid valve replacement was successfully performed with a 31 mm Carpentier-Edwards pericardial valve. The postoperative clinical course was smooth. This is the oldest known reported case of a successful operation for congenital tricuspid insufficiency.
