A long-term follow up study of 52 patients with acquired tricuspid regurgitation was carried out for 5.1 yr. The prognosis of 4 cases without surgical treatment for tricuspid regurgitation was poor. Other tricuspid regurgitation of 48 cases was surgically treated in association with mitral or mitral-aortic valve procedures. The tricuspid procedures were Carpentier's method in 29, DeVega's method in 12, Bex's method in 2 and valve replacement in 5. Early death occurred in 5 and late death in 1. There were no death due to tricuspid surgery. Dilatation of the tricuspid annulus was found in all cases and organic changes were in 13 (27%). Decreasing of heart size and improvement of general condition were recognized from early postoperative period in all groups. V-wave pressure of the right atrium significantly decreased in Carpentier's group after the operation but did not decrease in DeVega's group in spite of mild tricuspid regurgitation. The improvement of v-wave pressure in Carpentier's group was independent of the improvement of pulmonary capillary wedge pressure. Carpentier's method is proper for secondary tricuspid regurgitation without severe organic change.
