【摘要】 三尖瓣反流(TR)是最常见的心脏瓣膜病之一，其中继发性三尖瓣反流(STR)更为多见。STR的发病机制复杂，研究表明，心房颤动(AF)、射血分数保留的心力衰竭(HFp EF)、肺动脉高压(PAH)等与STR的发生密切相关。同时，左右心室之间存在相互依赖和协同作用，左心室疾病也会导致TR的发生。本文详细阐述了STR可能的发病机制，有助于疾病的早期诊断和干预，改善患者的预后。更多还原

【Abstract】 Tricuspid regurgitation( TR) is one of the most common valvular heart diseases,among which secondary tricuspid regurgitation( STR) is more prevalent. The pathogenesis of STR is complex. Studies have shown that atrial fibrillation( AF),heart failure with preserved ejection fraction( HFp EF),pulmonary arterial hypertension( PAH),etc.,are closely associated with the occurrence of STR. Meanwhile,there is an interdependence and synergistic effect between the left and right ventricles,and left ventricular diseases can also lead to the occurrence of TR. This article elaborates in detail on the possible pathogenesis of STR,which is helpful for the early diagnosis and intervention of the disease,and can improve the prognosis of patients.更多还原
