Heterologous aortic valves are used in many clinics as replacements for diseased human aortic and mitral valves. These valves possess all the advantages of homologous aortic valves and are more easily available to the surgeon. The heterologous valve also provides a greater choice of valve size than does the homograft; this can be of importance when replacing the mitral valve. Heterograft valves, like homografts, are usually preserved for periods ranging from a few days to a few months before insertion into a patient. Four methods of preservation, described, are currently in use. This study compares the effects of these four methods of preservation when pig valves are transplanted into the dog's aorta.
异种主动脉瓣在许多临床中被用作病变的人体主动脉瓣和二尖瓣的替代品。这些瓣膜具有同种主动脉瓣的所有优点，并且外科医生更容易获得。与同种移植瓣膜相比，异种瓣膜在瓣膜尺寸上也提供了更多选择；在置换二尖瓣时这可能很重要。与同种移植瓣膜一样，异种移植瓣膜在植入患者体内之前通常要保存几天到几个月。目前正在使用所描述的四种保存方法。本研究比较了将猪瓣膜移植到狗的主动脉中时这四种保存方法的效果。
