Abstract


BACKGROUND: The dimensions of the tricuspid valve complex will be useful in various medical fields, but very few articles are available in literature on the morphometry of the tricuspid valve. PURPOSE OF THE STUDY: The objective of this study is to describe in detail the morphometry of the Tricuspid valve in cadaveric human hearts in South Indian population. MATERIALS & METHODS: A cross-sectional, descriptive study was conducted on 45 cadaveric human hearts by conventional dissection technique and a detailed morphometry of the tricuspid valve was studied. RESULTS: The mean total annular length of the tricuspid valve orifice was 10.91 ±1.00cm. The mean annular length of each leaflets were 4.55 ± 0.51cm; 3.37 ± 0.76cm and 2.70 ± 0.69cm. The mean height of each leaflets were 1.82 ± 0.36cm; 1.60 ±0.31cm and 1.20 ± 0.43cm. The mean height of each commissures were 1.06 ±0.30cm; 0.74 ± 0.28cm and 1.04 ±0.32cm. CONCLUSION: The mean annular length & height of the leaflets of the tricuspid valve in south Indian population show a considerable difference with other Indian studies and also with western population. The measurements of the accessory leaflets and height of commissures were not available for the south Indian population in the literature, hence this study will be helpful for surgeons to plan commissurotomy and commissuroplasty for south Indian population.
