抄録

For the purpose of clinical evaluations of the Mitroflowvalve, we have measured effective valvuler orifice area (EOA), cardiac output at the heart rate of 90-180bpm made by the atrial pacing, and cineangiographic studies of cusp motion. The results were as follows: EOA were 2.28 (21A), 2.77 (23A), 3.12 (27M), 3.24, 3.52, 3.60cm2 (29M). The cardiac output increased up to 170bpm in 2 cases studied. Cineangiographic studies of the cusp movement showed synergic opening and closing of the 3 cusps and maximum opening of each cusp at mid diastole or systole.
