摘要
取脑死亡后25分钟～2小时内31例成年男性(20～40岁)的新鲜心脏,剖开展平心脏,用图像处理系统分别测量了二尖瓣纤维环、三尖瓣纤维环、主动脉瓣纤维环和肺动脉瓣纤维环的长度,其平均值分别为97.41±7.38、117.38±19.19、69.12±6.81和73.67±8.47mm.它们之间的比值依次为1∶1.2∶0.63∶0.76.经直线回归相关分析显示二尖瓣纤维环长度与其它三瓣纤维环,主动脉瓣纤维环与三尖瓣和肺动脉瓣之间存在密切相关.同时对二尖瓣前叶、后叶及交界区纤维环的长度进行了测量.
Cardiac valvular rings of mitral valve,aortic valve,tricuspid valve and pulmonary valve of 31 normal fresh hearts were measured respectively with image analysis system.The valvular rings were spread out when they were measured.The average lengths measured were 97.41±7.38,61.12±6.81,117.37±19.17 and 73.67±8.47mm respectively.The proportion of mitral valvular ring to aortic,tricuspid and pulmonary valvular ring was 1 to 0.63、1.20 and 0.76.
