Tricuspid valve dysfunction in the transplanted heart.
Mild degrees of tricuspid regurgitation are common in the orthotopically transplanted heart, probably secondary to the geometry of the right atrial anastomosis. At the University of Utah, 5 (0.95%) of 526 patients with transplantations performed from March 1985 to December 1993 have presented with severe tricuspid regurgitation requiring operative intervention. Echocardiographic findings confirmed at the time of operation consisted of ruptured chordae to the tricuspid valve. Standard tricuspid valve repair and replacement techniques were used with good results. We postulate the chordal disruption found in these patients is secondary to injuries incurred at the time of endomyocardial biopsy.
