Patients without residual tricuspid regurgitation
Recurrent TR after TA was recorded in 53 (14%) cases; 5-year adjusted
freedom from TR recurrence was significantly lower in patients with
preoperative RV remodeling (75±4% vs 91±3%, p<0.001; Figure
1).
In 114 (31%) patients RV was found remodeled at follow up; adjusted
5-year freedom from RV remodeling was 66±3%, significantly lower in
patients with preoperative RV remodeling (57±4% vs 79±5%,
p<0.001, Figure 2).
At multivariable analysis, similar risk factors were identified for TR
recurrence and RV remodeling: preoperative RV remodeling, preoperative
mild-or-moderate TR with TV remodeling, severe TR, preoperative
pulmonary pressure and functional MR (Tables 2-3).
Comparison between preoperative and follow up echocardiographic data are
summarized in the table 4.
Twenty-six patients died after discharge, 18 from cardiac or unknown
causes and 8 from non-cardiac causes. Eight-year survival was 88±3%.
Cox analysis with time-dependent variable confirmed TR recurrence and
late RV remodeling as risk factors for lower survival (Table 5, Figures
3-4).
