The effects of pulmonary hypertension severity on the outcomes of mitral valve replacement for rheumatic mitral stenosis

摘要

Background We performed this study to evaluate the effects of pulmonary hypertension (PH) severity on the hemodynamic and echocardiographic outcomes of mitral valve replacement (MVR) for rheumatic mitral stenosis (MS). Methods Patients with rheumatic MS were divided into two groups: Group-A with mean pulmonary arterial pressure (mPAP) equal to 26–40?mmHg and group-B with mPAP?>?55?mmHg. We compared the hemodynamic and arterial blood gases (ABG) data between both groups. Results Our analysis showed no significant difference between mild and severe PH groups in terms of all analyzed baseline and pre-operative data (p?
