The reported type of bioprosthesis is designed according to the numerical value measured on the aortic valve of the edible hog in Beijing area. Its frame is made from Delrin with a better flexibility. The stent, shorter than those commonly used, is 11 or 14 mm in height so as to be available for the replacement of each heart valve. The central angle between three roots is 120°. A ring-shaped base is modelled on the natural structure of the aortic ring itself. This design is conveniently applicable to surgical...

The reported type of bioprosthesis is designed according to the numerical value measured on the aortic valve of the edible hog in Beijing area. Its frame is made from Delrin with a better flexibility. The stent, shorter than those commonly used, is 11 or 14 mm in height so as to be available for the replacement of each heart valve. The central angle between three roots is 120°. A ring-shaped base is modelled on the natural structure of the aortic ring itself. This design is conveniently applicable to surgical operations and may avoid the possible obstruction in the outlet tract of the left ventricle. The bioprosthesis is treated with glutaldehyde conventionally, which showed a satisfactory result both in experimental and in our prelimilary clinical observations. Up to June 1980, this hioprosthesis has been applied in 5 cases in our hospital, the longest duration being over 9 months and proved to be favourable in valve functioning with improvement from the grade of Ⅳ to Ⅱ.

本型生物瓣膜依据对北京地区食用猪主动脉瓣测量数值而设计,以聚甲醛为支架,具有较好弹性。支架高度较一般常用者低,为11与14毫米,可用于心脏各瓣膜替换。三支脚中央夹角为120°。底部按主动脉环自然形态取环形结构。该设计便于手术操作,避免左心室流出道梗阻的可能性。生物组织沿用戊二醛处理方法经实验与初步临床观察均满意。至1980年6月,我院应用5例,最长者逾9个月,瓣膜功能良好,心功能由Ⅳ级上升为Ⅱ级。
