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.
Method: This six-month study was conducted in a tertiary center’s echocardiography lab. This study included 87 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 12-year age gap. 
Results: The participants ranged in age from 18 to 90, with 35 males (40/2 %) and 52 females (59/8%). By comparing tricuspid and mitral valve indices, this study found a difference between men and women (P<0.05). Furthermore, a difference in MV3D1, MV2CH1, MVPLAX1, MV3D2, MV4CH1, MV2CH1, MV ALAX2, MV2CH2, MV TENTING AREA, MV AREA indices at the mitral valve, and SAX2 TV4CH1, TV4CH2, TVSAX1, TVRVIF2 indices at the tricuspid valve was observed in various age groups (P-value<0.05).
Conclusions: Our findings confirmed that gender and age impacted echocardiographic parameters, with a trend of decreasing measurements after 65 years of age and the most significant dimensions obtained after 42 years of age.
