Intermittent severe mitral regurgitation.
The findings in two patients with hemodynamic evidence of intermittent severe mitral regurgitation with cyclic variation in right and left ventricular pressures are presented. Both patients had aortic and mitral valvular regurgitation of unknown etiology without definite evidence of papillary muscle dysfunction. The basis for the variation in the degree of mitral regurgitation is unclear.
