308 patients after aortic valve replacement by bio-prostheses were evaluated by questionnaire. The aim of the study was to estimate factors of risk for morbidity, which could be referred to the different xenogenic valve materials. After an average period of 41 months there was no statistical difference in postoperative status, such as exercise capacity, rate of survival and of freedom from thromboembolic events or repeat surgery. Although results of the early and intermediate postoperative period are satisfying with both types of valve prostheses a longer period of observation is required to draw distinct conclusions for xenogenic material related complications.
通过问卷调查对308例生物瓣膜主动脉瓣置换术后患者进行了评估。本研究的目的是评估发病风险因素，这些因素可能与不同的异种瓣膜材料有关。平均41个月后，术后状态如运动能力、生存率、无血栓栓塞事件或再次手术率等方面无统计学差异。尽管两种瓣膜假体在术后早期和中期的结果都令人满意，但需要更长时间的观察才能得出关于异种材料相关并发症的确切结论。
