The morphometry of tricuspid valve complex is of clinical importance for cardiovascular surgeons and there is scarcity of such data in Indian literature. The study was conducted to record normal tricuspid valve measurements which would serve as baseline data for the Indian population.
The study was carried out on 100 formalin fixed hearts without any pathology from patients who had died of non-vascular causes and whose age ranged from 8 to 85 yrs. The hearts were grouped into three cohorts corresponding to age, 54 hearts aged between 8 to 40 yrs, 42 hearts aged between 41 to 64 yrs and 4 hearts aged 65 yrs and above. Dissection was performed according to standard autopsy techniques. The measurements were recorded using a flexible millimeter ruler and surgical suture material. The dimensions measured were the attachment lengths of anterior, posterior and septal leaflets. The circumference of the valve along with the frontal and sagittal dimensions was measured. Area of the valve expressed as a triangle and as an ellipse was calculated.
The measurements obtained were assessed using SPSS software. Statistically significant increase in tricuspid valve measurements were observed with advancing age both in men and women. In younger hearts the tricuspid valve resembled a triangle and with advancing age the tricuspid valve became more elliptical in shape.
We hope this study will serve as baseline data for the tricuspid valve measurements in the Indian population and it will be of clinical use for patients with various tricuspid valve abnormalities.
三尖瓣复合体的形态测量对于心血管外科医生具有临床重要性，而印度文献中此类数据匮乏。本研究旨在记录正常三尖瓣测量值，为印度人群提供基线数据。
本研究对100例因非血管原因死亡、年龄在8至85岁之间且无任何病理改变的福尔马林固定心脏进行。心脏按年龄分为三组，54例年龄在8至40岁之间，42例年龄在41至64岁之间，4例年龄在65岁及以上。按照标准尸检技术进行解剖。使用柔性毫米尺和手术缝线材料记录测量值。测量的尺寸包括前叶、后叶和隔叶的附着长度。测量瓣膜的周长以及额面和矢状面尺寸。计算以三角形和椭圆形表示的瓣膜面积。
使用SPSS软件对获得的测量值进行评估。观察到随着年龄增长，男性和女性的三尖瓣测量值均有统计学显著增加。在较年轻的心脏中，三尖瓣类似三角形，随着年龄增长，三尖瓣形状变得更接近椭圆形。
我们希望本研究将作为印度人群三尖瓣测量的基线数据，对患有各种三尖瓣异常的患者具有临床应用价值。
