title: [Incidence of tricuspid valve prolapse].
abstract: The incidence of tricuspid valve prolapse and its association with mitral valve prolapse was studied in 100 patients with right- and left-ventricular angiography. Coronary artery disease was present in 81 patients (pts), a dilative cardiomyopathy in 6 pts, and a hypertrophic cardiomyopathy in 2 pts. 11 pts were angiographically normal. A total of 27 pts had a tricuspid valve prolapse, and 15 pts had a mitral valve prolapse. In 19 pts prolapse of the tricuspid valve was isolated, and in 8 pts it was associated with a mitral valve prolapse. The associated finding of a prolapse of the tricuspid and mitral valve was statistically significant (p less than 0.02). Patients with a tricuspid valve prolapse experienced a higher right-ventricular ejection fraction (58 + 10 vs 53 +/- 10%; p less than 0.05) and smaller end-systolic right ventricular volume indices (39 +/- 16 vs 47 +/- 17 ml/m2; p less than 0.05) compared to those without tricuspid valve prolapse. There was no further difference in clinical and hemodynamic parameters between those with and those without tricuspid valve prolapse. The clinical significance of a tricuspid valve prolapse is still undefined.
