Through aging, changes can occur in morphological structures of the heart valves. The objective is to examine the relationship between the dimensions of the rigth atrioventricular (tricuspid), pulmonary, left atrioventricular (mitral), and aortic valves and age at death. Sixty fresh human hearts were obtained . The age of individuals was between 20-90 years. We investigated the morphometric parameters of the valves were taken including: valve circumference, length, the height and area of each leaflet. All parameters were measured by using specific image analysis software. The correlation test and predictive equation were established. The positive correlation between the circumference, area of posterior leaflet, height of anterior leaflet, and area of anterior leaflet of the rigth atrioventricular valve were found. The left atrioventricular valve showed correlation with age in circumference, length and area of posterior leaflet. For the pulmonary and aortic valves, there were correlated between circumference at sinotubular junction and leaflet sizes in almost leaflets. The circumference at sinotubular junction of the pulmonary valve was highest significantly correlation with age (r=0.693). The predictive equation was age = -3.659+0.652(Circumference at sinotubular junction of the pulmonary valve) with standard error of ± 14.7 years. Additional knowledge of morphometric features in human heart valves and its relationship with age could be used as age indicator in forensic field.

Gross morphology and morphometry of native and decellularized heart valves of caprine: A comparative study

“…Contrast to our studies Gumpangseth et al. (2020) reported in humans that, the septal leaflet was the largest followed by posterior and anterior leaflets of tricuspid valve. Rohilla et al.…”

“…Contrast to our findings, Gumpangseth et al. (2020) reported that the length and height of three cusps were similar.…”

“…Similar findings were reported by Gumpangseth et al. (2020) in humans. Roy and Saha (2016) studied human mitral valves and stated that the mean annular attachments of both the anterior and posterior leaflets of bicuspid valve were similar and both the leaflets occupied similar annular circumference similar to our findings.…”

“…In their studies, contrasting findings were reported by Gumpangseth et al. (2020) in human aortic valves, where the non‐coronary cusp was greatest in height, length and area whereas the left coronary cusp was lowest in leaflet length and area. Our findings were in correspondence with Supadevi et al.…”

“…In their studies on human semilunar valves, Gumpangseth et al. (2020) reported that aortic valves were thicker than the pulmonary valves and all the three leaflets of aortic valve varied in size within the same individual.…”
