Background: The reliability and validity of echocardiography are critical issues. Day and age, defining normal cases necessitates expressing natural physiological differences, including ethnicity. OBJECTIVE: We are persuaded to evaluate average values in mitral and tricuspid valves in the Iranian population because only a few studies have been conducted to obtain average measures in echocardiography.Methods: This six-month study was conducted in a tertiary center’s echocardiography lab. This study included ۸۷ healthy Iranian volunteers who had no health issues. The tricuspid and mitral valves were examined using three and two-dimensional echocardiography. The investigated indicators produced normal data. The cases were divided into six age groups with a ۱۲-year age gap. Results: The participants ranged in age from ۱۸ to ۹۰, with ۳۵ males (۴۰/۲ %) and ۵۲ females (۵۹/۸%). By comparing tricuspid and mitral valve indices, this study found a difference between men and women (P-value<۰.۰۵). Furthermore, a difference in MV۳D۱, MV۲CH۱, MVPLAX۱, MV۳D۲, MV۴CH۱, MV۲CH۱, MV ALAX۲, MV۲CH۲, MV TENTING AREA, MV AREA indices at the mitral valve, and SAX۲ TV۴CH۱, TV۴CH۲, TVSAX۱, TVRVIF۲ indices at the tricuspid valve was observed in various age groups (P-value<۰.۰۵).Conclusions: Our findings confirmed that gender and age impacted echocardiographic parameters, with a trend of decreasing measurements after ۶۵ years of age and the most significant dimensions obtained after ۴۲ years of age.
