Tricuspid valve (TV) surgery carries high mortality and morbidity, and risk-adjusted mortality has not changed. Patients who can withstand the perioperative period benefit from symptomatic improvement as the right ventricle remodels. Risk stratification for patients undergoing surgical intervention is critically important. The Model for End-Stage Liver Disease (MELD) score is a reliable and accurate mortality risk predictor given the liver and kidney dysfunction that accompany tricuspid regurgitation. Novel clinical risk calculators for isolated TV surgery have also been developed to further guide patients with projected surgical outcomes and reinforce timeliness to intervention.

三尖瓣关闭不全的手术风险分层。

三尖瓣（TV）手术具有很高的死亡率和发病率，而经风险调整的死亡率并未改变。可以承受围手术期的患者可以通过对症状的改善来改善右心室，从而改善症状。对接受手术干预的患者进行风险分层至关重要。鉴于三尖瓣关闭不全伴有肝肾功能不全，终末期肝病模型（MELD）评分是可靠且准确的死亡风险预测指标。还开发了用于孤立电视手术的新型临床风险计算器，以进一步指导具有预期手术结果的患者，并加强干预的及时性。
