Patients with ischemic mitral incompetence have a high operative risk whether the valve is repaired or replaced. The advantage of repair over replacement is unclear in this subgroup of patients. ⋯ Patients with highly impaired LV function and ischemic mitral insufficiency are at high risk during valve repair or replacement, and cardiac transplantation should be considered for this group. However, patients with ischemic mitral insufficiency and moderately impaired LV function can undergo valve repair or replacement with an acceptable prognosis. The goal of mitral valve repair should be to reduce valvular insufficiency to at least grade I. If this is not the case, then the prognosis of repair is worse than after valve replacement. Thus, the surgeon should replace the valve during the same operation.

Patients with symptoms of right heart failure due to severe tricuspid regurgitation following a prior operation on left heart valves present a difficult problem. The outcome of tricuspid surgery in this setting is not well defined. We describe a single-center experience of isolated tricuspid valve surgery after prior left heart valve surgery, and analyze potential risk factors for a poor outcome. ⋯ Isolated tricuspid valve surgery for severe tricuspid regurgitation following prior surgery for left-sided heart valve disease can be performed with acceptable early mortality. There remains a high late mortality that is predicted only by age and the number of previous cardiac operations. However, in this selected group of severely symptomatic patients, significant improvement in symptoms are achieved in the survivors.
