Pre- and postoperative hemodynamic data in 10 patients in whom the aortic valve was replaced by a St. Jude Medical (SJM) prosthesis are compared with those in 29 patients who received a Lillehei-Kaster tilting disk (LK) valve prosthesis and 11 patients with a Björk-Shiley tilting disk (BS) valve prosthesis. The SJM aortic prosthesis of the small size (A 21) has advantages over the LK and BS types, and it is therefore particularly suited to use in a small aorta. There are also good hemodynamic results for the larger sizes of the SJM prosthesis. As a result of the 85-degree opening angle and the favorable ratio between the inner and outer diameters of the valve (suture ring), there is only minor impedance of blood flow. The SJM aortic prosthesis thus involves a lesser degree of hemolysis than the BS and the LK. In spite of the promising hemodynamic data, however, long-term findings on the durability of the SJM prosthesis in vivo have not yet been published. It therefore seems to us justifiable, especially where the aorta is large, to continue to use BS prostheses.
将10例接受圣犹达医疗（SJM）人工主动脉瓣置换术患者的术前和术后血流动力学数据，与29例接受 Lillehei-Kaster 倾斜碟瓣（LK）人工瓣膜置换术的患者以及11例接受 Björk-Shiley 倾斜碟瓣（BS）人工瓣膜置换术的患者的数据进行了比较。小尺寸（A 21）的SJM主动脉人工瓣膜比LK和BS型具有优势，因此特别适合用于小主动脉。较大尺寸的SJM人工瓣膜也有良好的血流动力学结果。由于85度的开口角度以及瓣膜（缝合环）内外径的有利比例，血流的阻抗很小。因此，SJM主动脉人工瓣膜引起的溶血程度低于BS和LK。然而，尽管血流动力学数据很有前景，但SJM人工瓣膜在体内耐久性的长期研究结果尚未发表。因此，我们认为，特别是在主动脉较大的情况下，继续使用BS人工瓣膜是合理的。
