| 目的 探讨血流汇聚法定量评价二尖瓣偏心反流的价值。方法 对63例二尖瓣偏心反流患者分别用连续方程法及血流汇聚法(PISA)测量二尖瓣反流程度,以连续方程法结果为标准,分析二者的相关性,建立线性回归方程。结果 血流汇聚法与连续方程法的结果之间有明显相关性(r＝0.838, P<0.05),并建立了直线回归方程。结论 血流汇聚法能较为准确地定量评价二尖瓣偏心反流程度,具有良好的应用前景。 |

| Objective To explore the value of the proximal isovelocity surface area method (PISA) in quantitative diagnosis of mitral valve eccentric regurgitation. Methods Sixty-three patients with eccentric mitral regurgitation were studied. The degree of regurgitation was evaluated with the continuity equation method and the proximal isovelocity surface area method. And those results were analyzed in their correlation and regression based on the continuity equation method as a "reference standard". Results The results of the proximal isovelocity surface area method had been found to have significant correlation(r=0.838, P<0.05) with the results of continuity equation method and built the regression equations between them. Conclusion The proximal isovelocity surface area method in quantitative diagnosis of mitral valve eccentric regurgitation had higher accuracy, it would be widely used in clinic. |
