Abstract:
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)em]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.
