Study on the Viability of Cryopreserved Aortae, Pulmonary Arteries, and Heart Valves 冷冻保存主动脉、肺动脉及瓣膜的活性研究
[ Results] After the reconstruction, all patients survive one year later. After 7 days and one year, color Doppler echocardiography showed pulmonary valves open and close well without obvious regurgitation, the pressure gradient was low; 结果重建术后1年,4位患者均存活,多普勒彩色超声心动图于术后7d、1年检查示肺动脉瓣膜关闭良好,无明显返流,跨瓣压差小;
The autologous aortic valves and sinuses were matched with the pulmonary valves and sinuses in shape and size. 主、肺动脉瓣叶及主、肺动脉窦在形态、大小上是匹配的。
Methods 30 TOF patients were divided into group A ( pulmonary valves function well) and group B ( pulmonary valves exhibit a poor function). 方法30名法洛四联症病人分成两个组,A组病人肺动脉功能发育良好,B组病人肺动脉发育不良。
According to the simulation results, the aortic valve, pulmonary valve, mitral valve and tricuspid valve closure timings and pressure gradient between both sides of the valves can be obtained. 根据仿真结果,得到主动脉瓣、肺动脉瓣、二尖瓣和三尖瓣的关闭时刻及瓣膜两侧的血压差。
