摘要
目的 观测家猪心脏二尖瓣复合体 ,为心脏研究和心脏移植积累资料。方法 甲醛固定的家猪心脏 35例 ,解剖并观测二尖瓣复合体。结果 家猪心脏二尖瓣复合体由瓣环、瓣膜、腱索和乳头肌构成 ,瓣环周长为 :73.0 0± 9.71mm ;前瓣、后瓣、前外侧连合、后内侧连合的高度分别为 17.45± 1.99mm ,16 .33± 2 .2 2mm ,5 .6 8± 1.37mm ,5 .35± 1.11mm ,前外侧连合和后内侧连合的宽度分别为 4.31± 0 .80mm ,4.40± 0 .6 3mm ;腱索起始前乳头肌 ,后又附着于前瓣 ,后瓣和后内侧连合的条数为 4.0 0± 1.30mm ,5 .2 1± 1.84和 2 .44± 1.16 ,起始后乳头肌 ,附着于前瓣、后瓣和前外侧连合的条数为 3.76± 1.78,5 .38± 2 .2 0和 2 .12± 0 .91。结论 家猪心脏二尖瓣复合体中各结构与人类相似 。
Objective To observe and measure the mitral complex in pig, in order to accumulate data for the further study. Methods The hearts of 35 pigs were fixed with 10% formaldehyde. The mitral complexes were dissected, observed and measured.Results The mitral complex of pig was composed of the mitral ring and valve, chordae tendinease and papillary muscles. The circle of mitral ring was 73.00±9.71?mm; the average height of anterior and posterior valve, anterior and posterior commissural area was 17.45 ±1.99?mm, 16.33±2.22?mm, 5.68±1.37?mm,15.35±1.11?mm respectively. The width of anterior and posterior commissural area was 4.31±0.80?mm, 4.40±o.63?mm separately. The average number of chordae tendineaes attached to anterior papillary muscle to anterior leaflet; posterior leaflet and anterior commissural area was 4.00±1.30, 5. 21±1.84, 2.44±1.16 respectively;The average number of chordae tendineases attached to posterior papillary muscle to anterior valve, posterior valve and posterior commissural area was 3.76±1.78, 5.38±2.20, 2.12±0.91 separately. Conclusion The mitral complex of pig heart is similar to human heart in morphology and structure in spite of the differences in size.
