The reliability and validity of echocardiography are critical issues. Day and age, defining normal cases necessitates expressing natural physiological differences, including ethnicity.
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.
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.
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).
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.
超声心动图的可靠性和有效性是关键问题。由于存在日龄和年龄差异，定义正常病例时需要考虑自然生理差异，包括种族因素。
鉴于仅有少数研究获取超声心动图的平均测量值，我们决定评估伊朗人群二尖瓣和三尖瓣的平均值。
这项为期六个月的研究在一家三级中心的超声心动图实验室进行。该研究纳入了87名无健康问题的伊朗健康志愿者。使用二维和三维超声心动图检查三尖瓣和二尖瓣。所研究的指标产生了正常数据。病例被分为六个年龄组，年龄间隔为12岁。
参与者年龄在18至90岁之间，男性35名（40/2%），女性52名（59/8%）。通过比较三尖瓣和二尖瓣指数，本研究发现男女之间存在差异（P<0.05）。此外，在不同年龄组中观察到二尖瓣的MV3D1、MV2CH1、MVPLAX1、MV3D2、MV4CH1、MV2CH1、MV ALAX2、MV2CH2、MV TENTING AREA、MV AREA指数，以及三尖瓣的SAX2 TV4CH1、TV4CH2、TVSAX1、TVRVIF2指数存在差异（P值<0.05）。
我们的研究结果证实，性别和年龄会影响超声心动图参数，65岁后测量值有下降趋势，42岁后获得的尺寸最为显著。
