Abstract:

Objective  To retrospectively analyze death risk factors of tricuspid valve replacement for patients with tricuspid regurgitation after cardiac surgery and evaluate the risk prediction of New EuroSCORE Ⅱ after tricuspid valve replacement. Methods  The clinical data of 77 patients who underwent the tricuspid valve replacement after cardiac surgery were retrospectively analyzed and univariate analysis and multivariate analysis were conducted. Results  The univariate analysis showed that NYHA class Ⅳ, right heart failure, elevated pulmonary artery pressure, total bilirubin, creatinine, urea, uric acid, sinus rhythm, cardiopulmonary bypass time, protection fluid, blocking time, and smaller prosthesis during the operation were statistically significant for early postoperative death (P<0.05). Elevated creatinine before operation and absence of atrial fibrillation were independent risk factors of early death of patients undergoing the tricuspid valve replacement after cardiac surgery (P<0.05). The difference of EuroSCORE between the death group and survival group was statistically significant. Conclusion  Attention should be paid to patients with abnormal renal function who will undergo the tricuspid valve replacement after cardiac surgery due to tricuspid regurgitation. New EuroSCORE Ⅱ is a reliable scoring system for predicting the risk of operation.
