Primary tricuspid valve regurgitation may be encountered in daily practice as a result of multiple etiologies. Described herein are the cases of 2 patients with severe primary tricuspid regurgitation. The underlying mechanism was posterior leaflet prolapse due to spontaneous chordae rupture in 1 case, and iatrogenic posterior leaflet tissue loss during removal of a permanent pacemaker in the other. Transthoracic and transesophageal echocardiography, which permit assessment of the tricuspid valve with multilevel imaging, are the techniques of choice for accurate detection and understanding of the etiology, the severity of valve regurgitation, and the determination of treatment options, in addition to providing assistance with timing and guidance during intervention. Three-dimensional echocardiography offers the ability to visualize the entire tricuspid valve and to identify which leaflets are affected by the pathology.
在日常临床实践中，多种病因可导致原发性三尖瓣反流。本文描述了2例严重原发性三尖瓣反流患者的病例。其中1例的潜在机制是自发性腱索断裂导致后叶脱垂，另一例是在移除永久性起搏器过程中发生医源性后叶组织缺失。经胸和经食管超声心动图能够进行多层面成像来评估三尖瓣，是准确检测和了解病因、瓣膜反流严重程度以及确定治疗方案的首选技术，此外还能在干预过程中提供时机和指导方面的帮助。三维超声心动图能够可视化整个三尖瓣，并识别哪些瓣叶受到病变影响。
