The purpose of this study was to assess the accuracy of planimetry after percutaneous balloon mitral valvuloplasty (PBMV). The mitral valve area (MVA) was estimated in 34 patients before and after PBMV, using two-dimensional echocardiographic planimetry, Doppler pressure half-time (PHT), and the Gorlin formula. There was no significant difference in the correlation of planimetry and PHT before (r = 0.53, p = 0.001) and after PBMV (r = 0.56, p < 0.001). A similar correlation was found between planimetry and the Gorlin formula (r = 0.44, p = 0.01 before PBMV, r = 0.37, p = 0.03 after PBMV). The concordance between planimetry, PHT, and the Gorlin formula in classifying patients into mild, moderate, or severe mitral stenosis was not worse after PBMV. Planimetry-derived MVA was not less accurate after PBMV than before PBMV. However, the correlation between the two echocardiographic measurements and the Gorlin formula was only moderate.
本研究的目的是评估经皮球囊二尖瓣成形术（PBMV）后平面测量法的准确性。在34例患者PBMV前后，使用二维超声心动图平面测量法、多普勒压力减半时间（PHT）和戈林公式估算二尖瓣面积（MVA）。PBMV前（r = 0.53，p = 0.001）和后（r = 0.56，p < 0.001）平面测量法与PHT的相关性无显著差异。平面测量法与戈林公式之间也发现了类似的相关性（PBMV前r = 0.44，p = 0.01；PBMV后r = 0.37，p = 0.03）。PBMV后，在将患者分类为轻度、中度或重度二尖瓣狭窄时，平面测量法、PHT和戈林公式之间的一致性并不比之前差。PBMV后由平面测量法得出的MVA准确性并不低于PBMV前。然而，两种超声心动图测量方法与戈林公式之间的相关性仅为中等。
