摘要
目的 观察和评价新型国产CL-V型双叶型人工机械心脏瓣膜的早期临床疗效和近期随访结果.方法 本组21例患者,行左房室瓣置换18例,左房室瓣及主动脉瓣联合置换3例.共植入进口瓣膜(23A)1枚,CL-V型双叶瓣23枚,其中CL-V型双叶瓣左房室瓣位21枚(25M 1枚、27M 20枚)、主动脉瓣位2枚(23A 1枚、25A 1枚).比较术前与术后1周、术后6个月心脏房室大小、心功能、血流动力学及血液相容性指标；观察围术期及随访中是否有瓣膜相关并发症.结果 随访率100％,随访时间6～61个月,平均随访时间19.8个月(1.7年).本组无早期死亡(术后30 d内),术后早期及近期随访中血流动力学性能稳定,血液相容性良好,未发现与瓣膜有关的并发症发生.结论 CL-V型双叶瓣的早期临床疗效满意,术后近期随访中未发现人工心脏瓣膜相关的并发症,远期疗效需进一步观察研究.
Abstract
Objective To introduce a new type of China-made bileaflet mechanical prosthetic heart valve (CL-V bileaflet valve) and evaluate its early clinical effectiveness and short-term follow-up outcomes. Methods Twenty-one patients were included in the present study, with 18 receiving mitral valve replacement and 3 receiving combined mitral and aortic replacement. One AST bileaflet valve(imported) and 23 CL-V bileaflet valves were implanted(21 in mitral position, including one 25M and 20 27M; and 2 in aortic position, including one 23A and one 25A). The ventricular and atrial volume, cardiac function, hemodynamics and hemocompatibility were compared before and one week, 6 months after operation. Valve-related complications were observed during perioperative period and follow-up. Results All the patients were followed up for 6-61 months, with a mean of 19. 8 months. There was no early mortality(< 30 d after operation). The patients had stable hemodynamics and satisfactory hemocompatibility early after operation and during short-term follow-ups there were no valve-related complications. Conclusion The early clinical results and short-term follow-up outcomes of CL-V bileaflet prosthetic valve are satisfactory, with no valve-related complications. The long-term outcome of CL-V bileaflet prosthetic valve needs to be further observed.
