The present study was performed to measure and calculate the mechanical force of percutaneous balloon valvotomy (PBV) for mitral valvular stenosis, using an equation pertaining to the mechanical force of the balloon needed to dilate the stenotic mitral valve. In case 1, the diameter of the mitral valve was enlarged by PBV from 1.43 cm to 2.40 cm and, in case 2, from 1.76 cm to 2.42 cm, with a mechanical force of 321 g and 436 g, respectively, following the equation.
本研究旨在通过一个与扩张狭窄二尖瓣所需球囊机械力相关的方程，测量并计算经皮球囊二尖瓣成形术（PBV）治疗二尖瓣狭窄的机械力。在病例1中，经PBV二尖瓣直径从1.43厘米扩大至2.40厘米，在病例2中，从1.76厘米扩大至2.42厘米，根据该方程，机械力分别为321克和436克。
