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).
