Key result
An atrial hydraulic shunt in an electrohydraulic total artificial heart increased cardiac output from 3 to >9 L/min at left atrial pressures of 0-15 mmHg, compensating for left-right flow differences.

May support atrial shunts for TAH flow balance in animals; hypothesis-generating and should not yet change practice.
An atrial hydraulic shunt in an electrohydraulic total artificial heart demonstrates Starling-like behavior and adequately compensates for physiologic left-right flow differences.
KUNG et al. (1993) studied Total Artificial Heart. Atrial hydraulic shunt in an electrohydraulic TAH was evaluated on Cardiac output and atrial pressure compensation. An atrial hydraulic shunt in an electrohydraulic total artificial heart increased cardiac output from 3 to >9 L/min at left atrial pressures of 0-15 mmHg, compensating for left-right flow differences.
