STUDIES OF THE MORPHOLOGY OF THE BIOPROSTHETIC HEART VALVES

对其形态的不同方面进行了几项研究 生物心脏瓣膜：1)在其中一项研究中，1%苯甲醇 在杜尔贝科的溶液中被发现是一种令人满意的存储介质 保留需要接受移植的生物人工心脏瓣膜 包括功能测试和形态研究。阀门放在这个里面 溶液保持适当的形态，不会变得过于僵硬(AS DO瓣膜保存在含醛固定剂中)；2)广泛的综述 非植入性和植入性胶原的形态观察 生物瓣膜，生物瓣膜的解剖变化 瓣膜作为植入前处理的结果，以及 这些瓣膜植入后发生的病理变化 瓣膜病患者的心脏瓣膜置换术。

Several studies were made of different aspects of the morphology of bioprosthetic cardiac valves: 1) in one of these studies 1% benzyl alcohol in Dulbecco's solution was found to be a satisfactory storage medium in which to keep explanted bioprosthetic heart valves that need to undergo both functional testing and morphological study. Valves kept in this solution retain adequate morphology and do not become excessively stiff (as do valves kept in aldehyde-containing fixatives); 2) Extensive reviews were made of the morphology of collagen in unimplanted and explanted bioprosthetic heart valves, of the anatomic changes that bioprosthetic valves undergo as the result of preimplantation processing, and of the pathological changes that develop after these valves are implanted as substitute cardiac valves in patients with valvular heart disease.
