Abstract

Purpose

Defining normative aortic echocardiographic values in each geographical district is crucial as aortic valve area (AVA) may vary across races, genders, and ages. Notably, variations in normal values can have implications for clinical decision-making, and available data on the Middle East population is also scarce. We sought to establish normal ranges for aortic valve echocardiographic parameters in the Iranian population and assess the effect of age, gender, weight, height, BMI, BSA, and blood pressure on them.

Methods

Our data were provided from the web-based echocardiographic data registry of Imam Khomeini Hospital Complex (IKHC). A total of 3251 healthy subjects older than 18 years old without any valvular stenosis were included in our study.

Results

AVA's normal range was estimated at 1.92–4.52 and 1.67–3.80 cm² in men and women, respectively. The annulus, AVA, AV VTI, and LVOT VTI were significantly larger in males, and this association remained significant after indexing AVA for weight, height, BMI, and BSA. Also, smaller AVA was associated with lower height, weight, BMI, and BSA in both men and women. Obese and hypertensive subjects had significantly larger AVA and annulus diameters.

Conclusion

Our study provided region-specific normal reference values for AV echocardiographic parameters and compared them across genders, ages, BMI, and blood pressure groups in the Iranian population.

重新审视二维超声心动图主动脉瓣面积的正常范围及其与年龄、性别和人体测量特征的关系

目的：确定每个地区的主动脉超声心动图正常值至关重要，因为主动脉瓣面积（AVA）会因种族、性别和年龄而异。值得注意的是，正常值的变化会对临床决策产生影响，而且中东地区人口的可用数据也很少。我们试图确定伊朗人群主动脉瓣超声心动图参数的正常范围，并评估年龄、性别、体重、身高、体重指数、BSA 和血压对这些参数的影响：我们的数据来自伊玛目霍梅尼综合医院（IKHC）的网络超声心动图数据登记。我们的研究共纳入了 3251 名 18 岁以上、无任何瓣膜狭窄的健康受试者：男性和女性的 AVA 正常范围分别为 1.92-4.52 和 1.67-3.80 平方厘米。男性的瓣环、AVA、AV VTI 和 LVOT VTI 明显更大，在将 AVA 与体重、身高、体重指数和 BSA 进行指数化后，这种关联仍然显著。此外，在男性和女性中，较小的 AVA 与较低的身高、体重、BMI 和 BSA 相关。肥胖和高血压受试者的 AVA 和瓣环直径明显更大：我们的研究为伊朗人口提供了特定地区的房室超声心动图参数正常参考值，并对不同性别、年龄、体重指数和血压组进行了比较。
