Tricuspid regurgitation (TR) is a very frequent manifestation of valvular heart disease. It may be due to the primary involvement of the valve or secondary to pulmonary hypertension or to the left-sided heart valve disease (most commonly rheumatic and involving the mitral valve). The pathophysiology of secondary TR is complex and is intrinsically connected to the anatomy and function of the right ventricle. A systematic multimodality approach to diagnosis and assessment (based not only on the severity of the TR but also on the assessment of annular size, RV function and degree of pulmonary hypertension) is, therefore, essential. Once considered non-important, treatment of secondary TR is currently viewed as an essential concomitant procedure at the time of mitral (and, less frequently, aortic valve) surgery. Although the indications for surgical management of severe TR are now generally accepted (Class I), controversy persists concerning the role of intervention for moderate TR. However, there is a trend for intervention in this setting, especially at the time of surgery for left-sided heart valve disease and/or in patients with significant tricuspid annular dilatation (Class IIa). Currently, surgery remains the best approach for the interventional treatment of TR. Percutaneous tricuspid valve intervention (both repair and replacement) is still in its infancy but may become a reliable option in future, especially for high-risk patients with isolated primary TR or with secondary TR related to advanced left-sided heart valve disease.
三尖瓣反流(TR)是一种非常常见的瓣膜性心脏病表现。它可能是由于瓣膜的原发性受累,也可能是由于肺动脉高压或左侧心脏瓣膜病(最常见的是风湿性疾病,累及二尖瓣)引起的。继发性 TR 的病理生理学较为复杂,与右心室的解剖结构和功能密切相关。因此,对诊断和评估(不仅基于 TR 的严重程度,还基于瓣环大小、RV 功能和肺动脉高压程度的评估)进行系统的多模态方法至关重要。尽管继发性 TR 的治疗曾被认为不重要,但目前在二尖瓣(以及较少情况下的主动脉瓣)手术时,将其视为必要的伴随手术。虽然目前普遍接受严重 TR 的手术治疗适应证(I 类),但对于中度 TR 的干预作用仍存在争议。然而,在这种情况下,干预的趋势越来越明显,尤其是在治疗左侧心脏瓣膜疾病和/或有明显三尖瓣瓣环扩张的患者时(IIa 类)。目前,手术仍然是治疗 TR 的最佳方法。经皮三尖瓣瓣膜介入治疗(修复和置换)仍处于起步阶段,但将来可能成为一种可靠的选择,尤其是对于孤立性原发性 TR 或与晚期左侧心脏瓣膜病相关的继发性 TR 的高危患者。
