摘要：
Devices provided herein can include implantable transseptal flow control components adapted to be implanted in an opening in a septal wall. In a closed configuration, the implantable transseptal flow control components provided herein prevent blood from flowing through the opening. In an open configuration, the implantable transseptal flow control components provided herein allow blood to flow from the left atrium to the right atrium. In a closed configuration, implantable transseptal flow control components provided herein can be configured such that blood does not stagnate at a location proximate to a left atrium flow control component side when the pressure differential is below a second predetermined threshold pressure value. Implantable transseptal flow control components provided herein can remain in a closed configuration when a pressure differential between the left atrium and the right atrium is less than a first non-zero predetermined threshold pressure value.
