Abstract:
Forty-five patients with Lillehei-Kaster pivoting disc valves had intraoperative assessment of valve hemodynamic function by simultaneous recording of aortic, left ventricular, and left atrial pressures and cardiac output. Mean transvalve gradients and prosthetic valve areas were calculated and recorded. Comparison of the results with data previously reported on the caged-ball valves indicates that the Lillehei-Kaster pivoting disc valve has superior hemodynamic characteristics.
