Abstract:
Objective: To evaluate the surgical results of aortic valve replacement with autologous pericardial valve. Methods: Nine patients underwent aortic valve replacement with autologous pericardial valve were studied by color Dopplor echocardiography (HP 1000 type). The mobility, thickness, opening amplitude, valve orifice areas, regurgitant stroke volume and transorifice pressure gradient of the autologous pericardial valves were measured and analysed intraoperatively and postoperatively. Results: 10 days postoperation, there was no significant difference in above mentioned indices between patients and normal group. Two years after operation, the mobility, thickness, opening amplitude, valve orifice areas, regurgitant stroke volume and transorifice pressure gradient of the autologous pericardial valves showed no significant changes, the EDV and LVEDD significant reduced as compared with 10 days postoperatively. Conclusion: Two years after operation, the structure and function of the autologous pericardial valve may maintain good condition.
