Abstract

OBJECTIVES

Histologically, the mitral valve annulus comprises a collection of collagen fibres. However, the existence of collagen fibres in the tricuspid valve annulus has not been elucidated. Our goal was to clarify the histology of the tricuspid annulus.

METHODS

Fifty human hearts without heart disease that were autopsied at Osaka City University Hospital between January 2009 and December 2017 were examined. The tricuspid valve was sectioned at 12 sites around the annulus, and the atrioventricular junction distance was measured.

RESULTS

None of the tricuspid valve annulus samples had a continuous aggregation of collagen fibres that could be called an annulus. The interventricular space between the right atria and ventricles was composed of adipose tissue only on the anterosuperior and inferior sides, and no adipose tissue was found on the septal side. Comparing the atrioventricular muscle distance of the anterosuperior and inferior sides, the distance at the inferior side was statistically significantly larger than that of the anterosuperior side in 47 cases (P < 0.0001).

CONCLUSIONS

There was no continuous circumferential aggregation of collagen fibres in the right atrioventricular junction. The distance between the right atrial and ventricular myocardium was greater at the inferior side than that at the anterosuperior side, which might lead to more inferior annular dilation versus anterosuperior dilation. These anatomical features will be fundamental for future discussions of the suturing method used in prosthetic ring annuloplasty for tricuspid regurgitation.

摘要

目的

组织学上，二尖瓣环由胶原纤维组成。然而，三尖瓣环中是否存在胶原纤维尚未阐明。我们的目的是阐明三尖瓣环的组织学结构。

方法

2009 年 1 月至 2017 年 12 月，在大阪市立大学医院进行尸检的 50 例无心脏病的人类心脏被纳入研究。在 12 个部位沿三尖瓣环切开三尖瓣，并测量房室结距离。

结果

三尖瓣环标本均无连续聚集的胶原纤维，不能称之为环。右心房和心室之间的室间隔仅在前上和下侧由脂肪组织组成，在间隔侧没有发现脂肪组织。比较前上和下侧房室肌距离，下侧的距离在 47 例中显著大于前上侧（P < 0.0001）。

结论

右房室交界处没有连续的胶原纤维环周聚集。右心房和心室心肌之间的距离在下侧大于前上侧，这可能导致下侧瓣环扩张较前上侧更明显。这些解剖特征将是未来讨论三尖瓣反流的人工瓣环成形术缝合方法的基础。
