Measurement of valvular annular area is necessary for valvular flow volumen quantification by Doppler echocardiography. The aim of this work was to compare normal valvular annular area values obtained in a necropsic and an echocardiographic series and to ascertain whether a relationship exists between these areas and several anthropometric variables.
Necropsic series: valvular annular area was measured in 20 hearts from deceased patients (age range: 9-79 years; mean 52 +/- 18) without cardiovascular disease. Echocardiographic series: Valvular annular area was determined in 156 patients (age range: 6-86 years; mean 37 +/- 20) without cardiovascular disease.
Necropsic series: multiple regression analysis showed valvular annular area values to be related mainly to height (p < 0.001) but also to weight (p < 0.01). Correlations between valvular annular area and body surface were low (r = 0.64-0.75). Aortic annular area index was slightly lower than the pulmonary annular area index and half that of the mitral annular area index (2.2 +/- 0.4, 2.5 +/- 0.5 and 4.4 +/- 0.8 cm2/m2, respectively). Tricuspid annular area index was the largest (6.7 +/- 1.0 cm2/m2). ECHOCARDIOGRAPHIC SERIES: Multiple regression analysis also showed a relationship between valvular annular area and height (p < 0.00001) and weight (p < 0.004). Correlations between valvular annular real values and body surface were poor (r = 0.45-0.71). Mean values of aortic, pulmonary and mitral valvular annular area indices were similar to those obtained in the necropsic series (2.1 +/- 0.2, 2.1 +/- 0.3, 4.1 +/- 0.6 cm2/m2, respectively). However, the tricuspid annular area index was clearly lower (4.5 +/- 0.6 cm2/m2, p < 0.001).
Valvular annular area is influenced mainly by height, but also by weight. The correlation between these values and body surface is poor. Aortic annular area is similar to the pulmonary annular area and half that of the mitral annulus. Normal values determined by echocardiography and necropsy are similar, although tricuspid annular area by apical view is smaller than that obtained in the necropsic series.
通过多普勒超声心动图对瓣膜血流容积进行定量分析时,测量瓣膜环面积是必要的。本研究旨在比较尸体解剖系列和超声心动图系列中获得的正常瓣膜环面积值,并确定这些面积与若干人体测量变量之间是否存在关联。
尸体解剖系列:在20例无心血管疾病的已故患者(年龄范围:9 - 79岁;平均52±18岁)的心脏中测量瓣膜环面积。超声心动图系列:在156例无心血管疾病的患者(年龄范围:6 - 86岁;平均37±20岁)中测定瓣膜环面积。
尸体解剖系列:多元回归分析显示瓣膜环面积值主要与身高相关(p < 0.001),但也与体重相关(p < 0.01)。瓣膜环面积与体表面积之间的相关性较低(r = 0.64 - 0.75)。主动脉瓣环面积指数略低于肺动脉瓣环面积指数,为二尖瓣瓣环面积指数的一半(分别为2.2±0.4、2.5±0.5和4.4±0.8 cm²/m²)。三尖瓣瓣环面积指数最大(6.7±1.0 cm²/m²)。超声心动图系列:多元回归分析也显示瓣膜环面积与身高(p < 0.00001)和体重(p < 0.004)之间存在关联。瓣膜环实际值与体表面积之间的相关性较差(r = 0.45 - 0.71)。主动脉、肺动脉和二尖瓣瓣环面积指数的平均值与尸体解剖系列中获得的值相似(分别为2.1±0.2、2.1±0.3、4.1±0.6 cm²/m²)。然而,三尖瓣瓣环面积指数明显较低(4.5±0.6 cm²/m²,p < 0.001)。
瓣膜环面积主要受身高影响,但也受体重影响。这些值与体表面积之间的相关性较差。主动脉瓣环面积与肺动脉瓣环面积相似,为二尖瓣瓣环面积的一半。超声心动图和尸检确定的正常值相似,尽管经心尖视图测量的三尖瓣瓣环面积小于尸体解剖系列中获得的值。
