Balloon valvuloplasty may improve LV compliance in mitral stenosis; hypothesis-generating and requires prospective confirmation before practice change.
Does balloon valvuloplasty improve left ventricular compliance in patients with mitral stenosis?
Balloon valvuloplasty acutely reverses the impaired left ventricular diastolic compliance seen in patients with mitral stenosis, suggesting the impairment is due to functional restriction by the thickened valve apparatus.
Liu et al. (1992) studied this question.
