In 70 consecutive patients with the clinical diagnosis of mitral valve disease quantification of the mitral valve area was performed by 2-D echocardiography. In only 39 of these 70 patients (58%) could the mitral valve be satisfactorily positioned in the short-axis view for correct quantification of the valve area. In 31 patients a sufficient echo could not be assessed because of anatomical disorders, calcification of the valve or postoperative deformities of the valve apparatus after commissurotomy. In 30 of the 39 patients, in whom 2-D echocardiography allowed to determine the valve area, the results of the echocardiographic study corresponded with the valve area determined by angiography using the modified Gorlin formula. A sufficient correlation between both methods, however, was found only in patients with combined mitral valve disease (r = 0.81); no correlation could be found in the group of patients with pure mitral stenosis. From these results we conclude that in the individual patient 2-D echocardiography is not sufficient for exact quantification of mitral stenosis. Definite preoperative diagnosis necessitates additional investigations.
对70例临床诊断为二尖瓣疾病的患者,采用二维超声心动图对二尖瓣面积进行定量分析。在这70例患者中,仅有39例(58%)的二尖瓣能在短轴视图中获得满意的定位,从而对瓣膜面积进行准确的定量分析。在31例患者中,由于解剖结构紊乱、瓣膜钙化或二尖瓣交界切开术后瓣膜装置的术后畸形,无法获得足够的回声。在39例可通过二维超声心动图测定瓣膜面积的患者中,有30例超声心动图研究结果与采用改良戈林公式通过血管造影确定的瓣膜面积相符。然而,仅在合并二尖瓣疾病的患者中两种方法之间存在足够的相关性(r = 0.81);在单纯二尖瓣狭窄患者组中未发现相关性。从这些结果我们得出结论,对于个体患者,二维超声心动图不足以准确量化二尖瓣狭窄。明确的术前诊断需要进行额外的检查。
