title: Mechanics of percutaneous balloon valvotomy for mitral valvular stenosis.
abstract: 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.
