The clinical and hemodynamic results of mitral balloon valvuloplasty for patients with mitral stenosis complicated by severe pulmonary hypertension

PBMV is a safe and effective procedure for patients with severe PH. It can remarkably improve clinical outcomes, although hemodynamic effects of PBMV on this subgroup are not complete. Pre-existing older age, more severe valvular lesion and tricuspid regurgitation, worse cardiac function, and bigger left atrial size in patients with severe PH may be important risk factors for the poor hemodynamic outcomes of PBMV.
