A cadaveric study: “Measurements of tricuspid valve using cardiac sizer in the North Karnataka Region”

Background: The right atrioventricular orifice is guarded by a complex called as tricuspid valve complex. The complex consists of atrioventricular orifice, annulus, leaflets, chordae tendineae, and papillary muscles. The right atrioventricular orifice passes the blood to the right ventricle in one-way direction, and this orifice is guarded by valve called as tricuspid valve. Tricuspid valve prevents the back flow of blood into the right atrium.Materials and Methods: This study was done on thirty human cadavers, which included 15 male and 15 female cadavers belonging to age group ranging from 50 to 70 years. Diameter of tricuspid valve was recorded using cardiac sizer and circumference of tricuspid valve was calculated by formula c = πd.Results: The average diameter of tricuspid valve in males was 26.06 ± 2.49 mm and in females was 24.33 ± 1.75 mm. The average circumference of tricuspid valve in males was 80.8 ± 7.72 mm and in females was 75.4 ± 5.45 mm.Conclusion: Clinically, during the replacement surgery of the tricuspid valve, surgeons are in need of actual circumference and diameter of tricuspid valve. Hence, the main objectives of this study are to measure the diameter and circumference of the tricuspid valve which will be helpful for cardiac surgeons, invasive cardiologists, and for preparation of synthetic (prosthetics) valve.
