Blood flow through this device follows a path that is nearly identical to the path through the normal heart. Flow rates in SynCardia patients are normally 7 to 9 L/min, and there is very little turbulence within the device. The pneumatically activated diaphragm system automatically balances blood output between the left and right sides and also automatically responds to increased venous return with increased outputs (Starling-like response). There is no suction.

To date, the longest duration of support has been 3.75 years, in a man who has since survived after transplantation. More than 47 patien...
