The long-term results on 36 patients undergoing tricuspid annuloplasty according to DeVega over the years 1981-1990 were analyzed. All had mitral valve replacement or repair in addition to the above procedure. Moreover, three patients had aortic valve replacement while aortocoronary bypass and interatrial septal defect closure was performed in two cases each. Duration of follow-up ranged between 6 to 72 months (mean 36 months). All patients were examined by echocardiography. Significant tricuspid regurgitation was found in three of the patients operated on, manifest clinical signs of the condition were present in one female patient only. Functional evaluation reassigned 72% of the operated patients from Class III and IV to Class I and II, and apparent subjective improvement was reported by 81% of patients. The analysis showed that indication of patients for simultaneous management of tricuspid regurgitation associated with mitral valve disease is justified, and that the surgical technique employed is appropriate.
