Outcomes Stratified for Two Epochs
Surgical strategies considerably changed since 2015, the application of leaflets augmentation increased the rate of TVr, and therefore we stratified patients into two epochs: 1999–2014 and 2015–2019 (Table 4). From 2015 to 2019, 87.1% of patients underwent e-RITS and 62.4% underwent TVr. Before 2015, 69.4% of patients underwent surgery with NYHA ≥ III, while the ratio decreased to 45% in the recent 5 years (p = 0.002), and only 12.5% underwent repair. In-hospital mortality also decreased from 16.7% to 6.9% (p = 0.044) and fewer patients underwent reoperation due to chest bleeding or poor wound healing (p = 0.011 and p = 0.021, respectively)
