Abstract
Devices and methods for treating heart disease by normalizing elevated blood pressure in the left and right atria of a heart of a mammal are disclosed. The devices are adapted to permit fluid flow across the membrane in which the device is implanted at first rate, and at a second rate, wherein a difference between the first rate and the second rate is not solely dependent upon variations in blood pressure differential across the membrane due to the heart's pumping cycle.
