We aimed at describing the different hemodynamic phenotypes of patients with pulmonary hypertension due to left heart disease before mitral valve replacement and/or concomitant aortic valve replacement and characterizing the impact of pulmonary hemodynamics on RV function. Subjects and method: 67 patients with pulmonary hypertension related to left heart diseases who underwent elective mitral valve replacement and/or aortic valve replacement enrolled in this prospective study from April, 2017 to April, 2018 at Hue Heart Center. Results and conclusions: Prevalence of three subgroups of patients pulmonary hemodynamics: isolated post-capillary pulmonary hemodynamics (Ipc - pulmonary hypertension); combined post- and pre-capillary pulmonary hypertension (Cpc - pulmonary hypertension); intermediate pulmonary hemodynamics were , and , respectively. Cpc pulmonary hemodynamics presented with slightly higher weight and body mass index than intermediate patients (p | The study on clinical phenotypes of pulmonary hypertension due to left heart disease at pre-operation time in patients with isolated mitral valve replacement or double valve replacement
