位于左心室和主动脉间的主动脉瓣,在心室收缩时开放,左心室内的血流进入主动脉射向全身,在心室舒张时候关闭,阻止主动脉内的血液返流回左心室,若发生主动脉关闭不全时,在心脏舒张期主动脉瓣不能关闭严密,造成血液从主动脉逆流入左心室。
目的:探讨主动脉瓣返流对胸主动脉结构与功能的影响。
Objective:To evaluate the influence of aortic valvular regurgitation(AR) on aortic remodeling.
我们要确保能够将器械输送到最佳位置,达到抑制主动脉瓣返流或不干扰冠脉血流的目的。
We need to make sure we deploy these devices exactly at the optimal position either for containment of aortic regurgitation or for the non-interference of coronary blood flow.
结论任何引起二尖瓣器质损害的疾病都能导致二尖瓣返流,主动脉瓣返流原因主要为瓣膜退行性变。
Conclusion Any disease which arose the mitral structure harm will lead to the mitral regurgitation. The main pathogeny of aortic regurgitation I...
