经食管超声心动图在牛心包主动脉瓣置换术中的应用

摘要

Objective To evaluate the appilcation value of intraoperative transesophageal echocardiography (IOTEE) in aortic valve replacement with bovine pericardium.Methods Totally 106 patients were ready to underwent the surgery of aortic valve replacement.The parameters of the aortic valves (diameter of aortic annular,aortic sinus and aortic sinus tube,effective height [eH]) were measured before cardiopulmonary by using IOTEE and during intraoperation.Results Eight cases were removed from the study due to supplemental preoperative diagnosis and modification of operative method,the rest of the 98 cases were enrolled.The coincidence rate of initial diagnosis hy using IOTEE and intraoperative diagnosis was 100 ％;5 cases (5/98,5.10 ％) of secondary diagnosis were inconsistent with intraoperative diagnosis.The coincidence rate of the number of aortic valves with preoperative IOTEE diagnosis and intraoperative diagnosis was 100 ％,the aortic valves perforation fistulas was 80.00％,the aortic valves vegetation was 85.71％,the senile calcified valvular disease was 100％,and the rheumatic disease was 100％.Diameter of aortic annular,aortic sinus and aortic sinus tube,eH measured by preoperative IOTEE had good correlation with intraoperative measurement (all r＞0.8,all P＜0.05).Conclusion IOTEE has feasibility and guiding value in aortic valve replacement with bovine pericardium,and is also of great significance to evaluate the prognosis of surgery.%目的 评价术中经食管超声心动图(IOTEE)在牛心包主动脉瓣置换术中的应用价值.方法 回顾性分析拟施行牛心包主动脉瓣置换术的106例患者,分别于体外循环前采用IOTEE测量和术中解剖测量主动脉瓣环径、主动脉窦部和主动脉窦管交界直径、主动脉瓣叶有效高度(eH).结果 术前拟行牛心包主动脉瓣置换术106例患者,其中8例经IOTEE术前补充诊断后修改手术方式被排除.余98例均接受牛心包主动脉瓣置换术.98例IOTEE首要诊断与手术诊断符合率为100％,5例(5/98,5.10％)IOTEE次要诊断与手术诊断不相符.98例患者体外循环前IOTEE提示瓣叶数目与术中探查符合率100％、瓣叶穿孔符合率80.00％,瓣叶赘生物符合率85.71％、老年退行性钙化符合率100％、风湿性病变符合率100％.体外循环前IOTEE测量的主动脉瓣环径、主动脉窦部和主动脉窦管交界直径、eH与术中实际测量结果相关性良好(r均＞0.8,P均＜0.05).结论 IOTEE对于评估牛心包主动脉瓣置换术的可行性、指导选择手术方案和预估手术效果有重要意义.
