  • 二尖瓣病变合并肺动脉高压致三尖瓣关闭不全的外科处理及中期随访

    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。

  • Echocardiography in Evaluation of Right Ventricular Function

    Abstract: Right ventricular dysfunction or right heart failure is a complex clinical syndrome and often leads to a poor prognosis and high mortality. In order to detect right ventricular dysfunction at an early stage, provide a therapy guidance and evaluate treatment outcomes, right ventricular function evaluation has aroused more and more concern in clinical physicians. With the advantages of being non-invasive, accuracy and repetitiveness, echocardiography is used extensively in the assessment of heart function. In this review, we focus on how to use echocardiography to evaluate right ventricular function easily, efficiently, accurately and sensitively, and provide a good foundation for its further clinical application.
