title: [A study of isolated tricuspid valve surgery late after left heart valve operation].
abstract: Management of severe tricuspid regurgitation late after left heart valve operation is controversial. There has been reluctance to the operation due to the high risk of repeat operation, coexistent right ventricular dysfunction and pulmonary hypertension. We investigated 6 cases of isolated tricuspid valve surgery (tricuspid valve replacement: 2, tricuspid valve plasty: 4) late after left heart valve operation. Before operation, these patients showed poor general condition (4 cases were NYHA III or IV) but good left ventricular function [mean ejection fraction (EF) 66 +/- 9.6%]. Hospital mortality was 0% and the mean mid-term actual event-free survival over 2 +/- 1.8 years was 80%. Most of patients demonstrated NYHA I and improvement of hepatomegaly after operation. There were many complications in 2 cases that had been performed previous operation more than 20 years before. In summary, the patient who complained symptoms due to right heart ventricular failure and showed good left ventricular function after left heart valve surgery should be considered to undergo tricuspid valve operation before the occurrence of other complications.
