近端等速度表面积（PISA）的原理和方法已经在人类和兽医学中进行了描述，特别强调了二尖瓣反流量化的便利性和速度。虽然在人类医学和兽医学中都描述了局限性，但就兽医学而言，临床实例没有得到很好的定义，在某些情况下没有单独提出。本文的目的是以定性的方式说明超声心动图中二尖瓣脱垂犬二尖瓣反流的动态行为和变异性的存在，这是一个需要考虑的因素，作为PISA技术固有的局限性。
The proximal isovelocity surface area (PISA) principles and methodology have been described in human and veterinary medicine with special emphasis given to the ease and speed for the quantification of mitral regurgitation. Although limitations have been described in both human and veterinary medicine, in the case of veterinary medicine, clinical examples have not been well defined and in some cases have not been individually presented. The objective of this paper is to illustrate in a qualitative manner the echocardiographic existence of the dynamic behavior and variability of mitral regurgitation in dogs with mitral valve prolapse, a factor to be taken into consideration as a limitation inherent to the PISA technique.
