目的 评价分段改良De Vega三尖瓣成形术治疗功能性三尖瓣关闭不全（FTR）的临床疗效，总结治疗经验。 方法 选择2006年10月至2007年12月在我院手术治疗的风湿性二尖瓣病变合并FTR患者共58例，根据三尖瓣成形手术方式的不同分为两组，改良组：26例，男8例，女18例；年龄49.6±11.8岁；接受分段改良De Vega三尖瓣成形术。传统组：32例，男6例，女26例；年龄47.9±12.8岁；接受传统改良De Vega三尖瓣成形术。于围手术期用超声心动图测量两组患者三尖瓣瞬时反流量、三尖瓣瓣环周径，并随访术后三尖瓣反流情况。 结果 两组术后三尖瓣瞬时反流量均较术前减少（Plt;0.05），组间比较差异无统计学意义（F=1.969，Pgt;0.05）；三尖瓣瓣环周径均较术前明显缩小（Plt;0.01），组间比较差异无统计学意义（F=2.336，Pgt;0.05）；两组均无因三尖瓣反流再次手术者。随访6~12个月时，两组患者三尖瓣反流情况较出院前明显改善，组间比较差异无统计学意义（Pgt;0.05）。 结论 分段改良De Vega三尖瓣成形术，能较为有效地纠正FTR，并可取得满意的近期疗效。

Abstract： Tricuspid insufficiency founded in the setting of left-sided heart disease is usually secondary tricuspid insufficiency caused by tricuspid valve annular dilation. Some patients had rheumatic tricuspid valve diseases. Tricuspid valve repair rather than valve replacement is recommend for functional tricuspid regurgitation. Linear annuloplasty and ring annuloplasty are two main tricuspid valve repair methods. However, the indications for treatment of secondary tricuspid regurgitation remain controversial. The optimal surgical repair technique to eliminate secondary tricuspid regurgitation remains challenging. In this article, we review the assessment of tricuspid valve lesions, criteria for correction, and surgical management of secondary tricuspid insufficiency.methods. However, the indications for treatment of secondary tricus

目的总结二尖瓣置换术后三尖瓣关闭不全患者的外科治疗经验。方法14例心脏瓣膜疾病患者行二尖瓣置换术后发生中度或重度三尖瓣关闭不全,其中相对性关闭不全12例,器质性关闭不全2例。行三尖瓣成形术4例,均使用人工瓣环成形;行三尖瓣置换术10例,其中置换生物瓣6例,双叶机械瓣4例。在心脏不停跳下手术4例,常规心脏停搏手术10例。结果全组无手术死亡,术后发生低心排血量综合征3例,用升压药维持循环,患者均顺利出院。术后复查超声心动图,右心房、室均明显缩小,右心室前后径(22.5±5.6mm)较术前(31.9±5.9mm)明显减小(Plt;0.001)。随访14例,随访时间1.8±1.3年,心功能级2例、级9例,级2例,1例于术后4年因心力衰竭死亡。结论二尖瓣置换术后远期三尖瓣关闭不全的患者经外科矫治后疗效满意,合理掌握手术指征、手术时机和良好的围术期治疗是手术成功的关键。

We reported a 54-year-old female patient with severe tricuspid regurgitation, who received mechanic valve in the mitral position 15 years ago. The patient’s Society of Thoracic Surgeons score was 8.27%, and was intolerant to open heart surgery, so she was recommended for transcatheter tricuspid valve replacement via right vena jugularis interna. The procedures were guided by echocardiography and X ray fluoroscopy on November 13, 2021, the prosthesis was implanted successfully, and the patient was recoved without any adverse events. After 1 month follow-up, her general condition was apparently improved.

In historic perspectives, tricuspid valve was considered as “forgotten valve” in the cardiovascular field. Tricuspid regurgitation (TR) is the main disease of the tricuspid valve, and the number of patients is large. TR patients have mostly treated conservatively with drugs due to high surgical mortality, so the effective treatment of TR patients is far from satisfactory. With the development of interventional technology, transcatheter tricuspid valve intervention (TTVI) is expected to become a better choice. In recent years, a number of TTVI devices have entered clinical trials and achieved good results. Due to the late development of TTVI technology and insufficient accumulation of clinical applications, there are no uniform inclusion criteria and evaluation indicators for research endpoints when conducting clinical trials. This article focuses on the introduction of different instruments of TTVI, and summarizes the current status, research progress and problems of these treatments.

Right-sided cardiac valvular diseases have traditionally been considered less important than disease of mitral or aortic valve. However, severe tricuspid regurgitation could lead to right ventricle dysfunction and reduce patients' survival rate. In clinic setting, tricuspid valve disease should be paid more attention for patients with secondary tricuspid regurgitation caused by left-sided valvular surgery combined with irreversible annular dilatation increasing the risk of re-operation. In this review, we summarize the epidemiology, anatomy, pathology, diagnosis, ultrasound and cardiac magnetic resonance imaging findings in patients with tricuspid regurgitation.

目的 探讨二尖瓣病变合并肺动脉高压致三尖瓣关闭不全外科治疗的方法，总结相关治疗经验。 方法 回顾性分析2005年6月至2011年6月我院行外科手术治疗二尖瓣病变合并肺动脉高压致三尖瓣关闭不全118例患者的临床资料，男52例、女66例，年龄31～68 （48.25±9.83） 岁。三尖瓣轻度反流28例，中度反流59例，重度反流31例。所有患者术前均有不同程度的肺动脉高压（38～82 mm Hg）。术中行二尖瓣手术时同期行三尖瓣手术。体外循环停机后，术中采用经食管超声心动图（TEE）评价术后即刻治疗效果，出院前再次复查经胸超声心动图评价手术治疗效果。 结果 术中TEE结果提示，三尖瓣无反流50例，轻度反流67例，1例患者三尖瓣成形术后仍存在重度反流，遂再次在体外循环下行三尖瓣置换术。术后早期死亡4例（3.39%），其余患者均痊愈出院。随访12～84（41.72±22.90） 个月，完整随访105例，远期死亡3例，其余患者三尖瓣无反流30例，轻度反流66例，中度反流4例，重度反流2例。全组患者术后5年生存率为93.6%±2.4%；术后5年三尖瓣免除再手术率为94.9%±3.6%。 结论 对二尖瓣病变合并肺动脉高压所致的功能性三尖瓣关闭不全患者，在解决二尖瓣病变时同期纠治存在的三尖瓣病变，可降低术后三尖瓣的再手术率，早、中期疗效满意。术中根据三尖瓣瓣环的扩张程度选择适当的手术方式是提高手术治疗效果的关键。
