Twenty-five years' clinical experience with repair of tricuspid insufficiency

Abstract

Background and aim of the study: Tricuspid regurgitation secondary to pulmonary hypertension due to left-sided heart valve lesions is common. Here, the results are reported of 25 years' experience with three surgical techniques; the De Vega semicircular annuloplasty, the Bex flexible linear reducer, and the Carpentier-Edwards prosthetic ring annuloplasty.

Methods: Between 1976 and 2002, 463 patients underwent 478 tricuspid annuloplasty procedures to correct valve regurgitation during associated left-sided valve surgery. Patients were followed prospectively at the Montreal Heart Institute Valve Clinic.

Results: A total of 107 patients (23%) underwent the De Vega semicircular annuloplasty, 267 (58%) the Bex flexible linear reducer, and 89 (19%) the Carpentier-Edwards prosthetic ring annuloplasty. Excluding 30-day mortality, the mean 5-, 10- and 15-year patient survival was 82+/-4%, 58+/-6% and 30+/-6% respectively after the De Vega semicircular annuloplasty, 76+/-3%, 54+/-4% and 36+/-6% respectively after the Bex flexible linear reducer, and the mean five-year patient survival was 88+/-4% after the Carpentier-Edwards prosthetic ring annuloplasty (p = 0.65, for comparison of the three survival curves). The mean freedom rate from tricuspid repair failure (clinical right heart failure, redo annuloplasty, tricuspid valve replacement at follow up) was 95+/-3%, 93+/-3% and 72+/-8% at 5, 10 and 15 years respectively after the De Vega semicircular annuloplasty, and 97+/-1%, 87+/-4% and 66+/-9% after the Bex flexible linear reducer. The mean freedom rate from repair failure was 94+/-3% at five years after the Carpentier-Edwards prosthetic ring annuloplasty (p = 0.18 for comparison of the three freedom from failure curves).

Conclusion: All three techniques of tricuspid valve repair resulted in a low rate of failure, and in good patient survival at long-term follow up.
