Postoperative hemodynamics of 36 patients who underwent valve replacement was evaluated. The 17 patients underwent AVR (BS11, SJM5, H1), the 6 patients, AVR+CNC (BS) and the 13 patients, MVR (BS6, SJM2, H1, ISL).<br>In AVR group, the Björk-Shiley valve was stable hemodynamics at tachycardia state, for example when the heart rate was 120/min, cardiac output showed 5.08±0.27L/min in the Björk-Shiley valve, 4.77±0.43L/min in the SJM valve.<br>In MVR group, the Ionescu-Shiley valve was good hemodynamics as the heart rate increased, for example the cardiac output showed 3.95±0.35L/min at spontaneous rate, 4.86±0.32L/min at 80/min, 4.91±0.33L/min at 100/min and 4.94±0.51L/min at 120/min.<br>In conclusion, the Björk-Shiley valve was better for the aortic valve replacement, and the Ionescu-Shiley valve was better for the mitral valve replacement.
