Operative Data and Postoperative Outcomes
Table 2 presents surgical data and postoperative outcomes for all the 173 patients. 101 patients underwent tricuspid valve replacement (TVR), including implantation of 83 (58.4%) biological tricuspid valves and 18 (10.4%) mechanical tricuspid valves; 72 (41.6%) patients underwent TVr. The overall surgical volume increased in recent years, and the ratio of TVr increased from 9.0% to 76.2%.
In-hospital deaths occurred in 19 patients for a mortality rate of 11.0%. There was no significant difference between the m-RITS and e-RITS groups (p = 0.234). The causes were heart and multi-organ failure (n = 12, 63.2%), cardiac arrest (n = 2, 10.5%), infective endocarditis (n = 1, 5.3%), lung infection (n = 2, 10.5%), stroke (n=1, 5.3%) and severe gastrointestinal bleeding (n = 1, 5.3%). The overall median cardiopulmonary bypass (CPB) time was 98.0 (75.0–118.5) minutes, and CPB time in the e-RITS group was longer than in the m-RITS group (p <0.001). Patients in the e-RITS group had shorter intensive unit care stays and a lower proportion of reoperation for chest bleeding or poor wound healing. Univariable and multivariable logistic regression analyses indicated that replacement and NYHA function class IV were independent risk factors of in-hospital mortality (Table 3).
