“…The rigth atrioventricular valve circumference and height of anterior leaflet were used to create the equation for age estimation in which the standard error was 15.8 and 16.4, respectively. The circumference of the left atrioventricular valves was more variations and greatest among other literatures (Roy & Saha, 2016). The area of left atrioventricular leaflets was similar to the study of Gupta et al (2012).…”

Int. J. Morphol., 38(3):726-730, 2020. SUMMARY:Determination of age represents one of the most important aspects in forensic identification. 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.

“…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.…”

The gross morphological examination of native caprine heart valves revealed distinctive structural characteristics of the caprine's cardiac anatomy. Four primary orifices were identified, each protected by thin, valve‐like structures. Atrioventricular orifices featured tricuspid and bicuspid valves, while the aorta and pulmonary arteries were guarded by semilunar valves. Within the atrioventricular apparatus, distinct features were observed including the tricuspid valve's three leaflets and the bicuspid valve's anterior and posterior leaflets. Ultrasonography provided insights into valve thickness and chordae tendineae lengths. Morphometric studies compared leaflets/cusps within individual native valves, showcasing significant variations in dimensions. Comparative analysis between native and decellularized valves highlighted the effects of decellularization on leaflet thickness and chordae tendineae lengths. Decellularized valves exhibited reduced dimensions compared to native valves, indicating successful removal of cellular components. While some dimensions remained unchanged post‐decellularization, significant reductions were observed in leaflet thicknesses and chordae tendineae lengths. Notably, semilunar valve cusps displayed varying responses to decellularization, with significant reductions in cusp lengths observed in the aortic valve, while the pulmonary valve exhibited more subtle changes. These findings underscore the importance of understanding structural alterations in heart valves post‐decellularization, providing valuable insights for tissue engineering applications and regenerative medicine.

“…19 The present mean value was also lower than the values of other observers. 21,26 Though there was no direct relation between the diameter and the annular circumference of the same valve, generally with larger circumference the diameter was found to be longer. Usually the diameter and circumference of tricuspid annulus were higher than the mitral annulus and in living the diameter was marginally at the lower range.…”

“…The mean annular circumference of mitral valve in present study was 9.22 ± 1.49 cm (Table 4) which was similar with the values of many other observers. 14,16,17,26 and higher than the value of Andrade where the fresh cadaveric hearts were included in the study. 11 This difference is probably because in fresh cadavers the elasticity of the soft tissue is still maintained resulting in smaller dimension.…”

The human heart valve is an integral structure and the valvular heart disease is one of the most common disease of the heart. Such cardiac disease require repair of the valve and valve replacement surgery where the patient’s diseased valve is replaced by a prosthetic valve. The aim of this study was to measure the annular circumferences and diameters of tricuspid and mitral valves in cadavers. A morphometric study was conducted in Department of Anatomy at Nepal Medical College and Teaching Hospital where total 50 cadaveric hearts were taken up for the study. The tricuspid and the mitral valves were exposed by dissection method. Measurements were taken by using a thread and a digital vernier caliper and obtained data were analysed by using SPSS-16. The mean, frequency and standard deviation of circumferences and diameters of both tricuspid and the mitral valves were analysed and were found as (a) The mean annular circumference of tricuspid valve was 11.22 ± 0.20 cm (b) The mean diameter of tricuspid valve was 2.33 ± 0.04 cm. (c) The mean annular circumference of mitral valve was 9.22 ± 1.49 cm (d) the mean diameter of mitral valve was 2.01 ± 0.27 cm. There were few literatures available on the study of cadaveric heart valves in Nepal thus this study will provide a guideline to the clinicians, radiologists and also to cardiothoracic surgeons performing various valve surgeries to assess the prosthetic valve of appropriate size and to the anthropologists also to maintain a standardized data on cardiac valves as well.
