- W2348254920 abstract "Objective To explore the effect of pulmonary ateriolar stenosis complicated with mitral stenosis (the secondary stenosis) on restoration of pulmonary pressure following successful percutaneous balloon mitral valvuloplasty (PBMV) Methods A total of 523 patients with pulmonary hypertension due to mitral stenosis were studied Systolic pulmonary artery pressure (PASP) and systolic left artium pressure (LASP) of them were measured by catheter pre valvuloplasty and post valvuloplasty The patients were divided into two groups: Group A including 109 patients with severe pulmonary hypertension (PASP≥70 mm Hg) pre valvuloplasty and Group B including 414 patients with mild to moderate pulmonary hypertension (PASP70mm Hg)pre valvuloplasty The two groups were compared on hemodynamic changes after PBMV The logistic analysis was performed to evaluate the factors determining normalization of PASP after PBMV Results The level of PASP pre valvuloplasty was confirmed to be one of the most significant independent predictors of PASP normalization according to the result of logistic regression The proportion of patients with normal PASP post valvuloplasty in group A(4 5%) was much lower than that in group B(42 5%) The correlation between LASP and PASP in group B was much better than that in group A Conclusion The secondary stenosis due to anatomic changes in pulmonary arteriolar is the major factor determining normalization of pulmonary pressure following PBMV on mitral stenosis with pulmonary hypertension" @default.
