摘要
目的应用经胸和经食管超声心动图评价牛心包置换单叶主动脉瓣治疗主动脉瓣关闭不全的效果。方法应用经胸和经食管超声心动图对25例牛心包置换单叶主动脉瓣治疗主动脉瓣关闭不全患者行术前、体外循环停机后术中检测和术后3～6个月随访，判定瓣膜结构、病变和反流程度，同一切面相同时相测量手术前后左房、左室内径。结果25例患者术前经胸超声检测反流与停机后术中反流程度差异有统计学意义（P〈0．001）；术中停机后经食管超声与术后3～6个月经胸超声检测反流程度比较差异无统计学意义（P〉0．1）；术后3～6个月左房内径[（3．19±0．90）cm]、左室内径[（4．72±1．19）cm]较术前[左房（3．80±1．37）cm，左室（5．75±1．32）cm]明显回缩，手术前后测值差异有统计学意义（P〈0．001）。结论牛心包置换单叶主动脉瓣治疗主动脉瓣关闭不全近期疗效较好，远期效果尚待观察。
Objective To evaluate the value of single leaflet replacement of bovine pericardium in the treatment of aortic valve insufficiency using transthoracic echocardiography （TTE） and transesophageal echocardiography（TEE）. Methods TTE and TEE examination were performed for 25 cases pre-operation, postpump intraoperative and 3-6 months after the operation, to judge the structure and the regurgitation of the aortic valve. And the inside diameter of left atrium（LA） and left ventricle（LV） in the same plane and the same phase were also been measured. Results The degree of aortic regurgitation（AR） before operation were significantly different with that postpump intraoperative （P〈0.001） evaluated by TEE. There was no difference in the degree of AR by postpump intraoperative TEE and those of AR by TTE 3-6 months after surgery （P〉0.1）. The inside diameter of LA [（3.80±1.37）cm] and LV [（5.75±1.32）cm] before repair were larger than those 3-6 months after surgery [LA（3.19±0. 90）cm, LV（4.72±1.19）cm, P〈0.001]. Conclusions The replacement of single aortic valve with bovine pericardium to treat aortic valve insufficiency is a good alternative for patients with satisfactory short-term results,but long-term results are not clear.
