Abstract
A stable model of left ventricular failure is required to test left ventricular assist devices. Supravalvular aortic constriction will cause left atrial pressure to rise to new levels which are stable for several days. When left atrial pressure becomes unstable, an automatically actuated left ventricular assist device will increase its output and prevent pulmonary edema.
摘要
测试左心室辅助装置需要一个稳定的左心室衰竭模型。主动脉瓣上缩窄会使左心房压力上升到新的水平，并在数天内保持稳定。当左心房压力变得不稳定时，一个自动启动的左心室辅助装置会增加其输出并防止肺水肿。
