The diagnosis of tricuspid insufficiency; clinical features in 60 cases with associated mitral valve disease.

In a series of 146 patients with mitral stenosis studied by cardiac catheterization, 60 were found to have right atrial pressure curves diagnostic of tricuspid insufficiency. The clinical and hemodynamic features of these patients are reviewed. The oft-cited, classic manifestations of tricuspid insufficiency were found with relative infrequency and the diagnosis had been made clinically in less than one fourth of the cases. Modification of criteria for the diagnosis of tricuspid insufficiency is suggested.
