摘　　要：目的探讨三维等速表面积法(3D-proximal isovelocity surface area,3D PISA)评价二尖瓣反流的可行性研究。方法于2015年3—8月在该院检查发现二尖瓣反流病例70例,其中偏心性反流46例,分别给与2D PISA及3D PISA定量评价二尖瓣的反流程度。结果 2D PISA及3D PISA所测反流口面积差异有统计学意义,3D PISA的反流口面积要高于2D PISA,平均有效反流口面积对于定量评价二尖瓣反流更实用。结论 3D PISA作为一种新的定量评价二尖瓣反流程度的方法应该得到广泛的应用。Objective Feasibility of three dimensional proximal isovelocity surface area in quantitative evaluate mitral regurgitation. Methods Sevevnty patients who diagnosed mitral valve regurgitation,we use different method 2D PISA and 3D PISA quantitative evaluate the degree of mitral regurgitation. Results The results of this study demonstrate the area of 3D PISA more than 2D PISA.diagnostic value of an averaged effective orifice area are more utility. Conclusion 3D PISA a new method of evaluate the degree of mitral regurgitation should be used in clinic practice.
