Multivariable Cox regression analysis revealed that ascites (HR, 5.8 p = 0.01), and right ventricular dysfunction (HR, 0.94 p = 0.001) were predictors of major adverse cardiac events. The operative mortality rate was 15.4% (n = 4) and the cumulative survival at 1, 5 and 10 years was respectively 80% ± 8%, 75.6% ± 8.7% and 67.2% ± 11.1% with no significant difference at 8 years between tricuspid valve replacement (80% ± 12.6%) and repair (57.6% ± 16.1%) (p = 0.5). Follow-up was 96.1% complete, with a mean follow-up of 55.6 ± 38.8 months (range 1 to 165). Surgery consisted of 15 ring annuloplasty and 11 tricuspid valve replacement (5 bioprostheses and 6 mechanical prostheses). Ten patients (38.5%) had previous tricuspid valve repair. The mechanism of tricuspid regurgitation was functional and organic in respectively 14 (53.8%) and 12 cases (46.2%).
The mean age was 48.2 ± 8.6 years with 8.3% as sex-ratio (M/F). Twenty six consecutive rheumatic patients who underwent isolated tricuspid valve surgery after left-sided valve surgery between January 2000 and January2017 were retrospectively registered in the study.
The aim of this study was to analyze short and long-term results and outcome of tricuspid valve surgery after left-sided valve surgery in rheumatic patients. The reoperation for isolated tricuspid regurgitation in rheumatic population is rare and still unclear and controversial because of the rarity of publications.
