FLAIL TRICUSPID-VALVE IN AN ADULT PATIENT WITH CONGENITALLY CORRECTEDTRANSPOSITION OF THE GREAT-ARTERIES

We describe a case of a 50-year-old woman with congenitally corrected transposition of the great vessels, in whom severe left-sided tricuspi d (systemic atrioventricular) value insufficiency was the only associa ted anomaly. The tricuspid valve was dysplastic and abnormally oriente d toward the interventricular septum, without the downward displacemen t of Ebstein's anomaly. The mechanism of atrioventricular regurgitatio n was unusual in that it consisted of the rupture of chordae tendineae of both the anterior and septal leaflets. The left-sided tricuspid va lve was replaced with a St. Jude prosthesis and the postoperative cour se was uneventful.
