Abstract
Among 100 consecutive patients undergoing mitral valve replacement, 28 had clinically and hemodynamically significant tricuspid regurgitation without tricuspid stenosis. In 21 patients the mitral valve was regurgitant, and in eight it was stenotic. The characteristic murmur of tricuspid regurgitation was present in 27 patients; 25 had abnormal venous distention, 14 peripheral edema, and seven ascites; and in 27 the liver was enlarged more than 4 cm below the costal margin. The mean right atrial pressure was abnormally high in every patient (average 11 mm Hg), and 25 had severe pulmonary hypertension (average systolic pressure 75 mm Hg). At the time of mitral replacement, 25 patients had no operative procedure on the tricuspid valve, and three had a tricuspid annuloplasty. Four patients died, a mortality rate (14%) not different from that in the patients without tricuspid regurgitation. Twenty-four patients were reassessed at postoperative intervals of one to four years (average 30 months). All evidenced s...
