Evaluation of Advanced Echocardiographic Parameters of Right Ventricular in Patients with Pulmonary Hypertension
Background and Objective: Pulmonary hypertension is an increase in blood pressure of the pulmonary artery which leads to right ventricular dysfunction. Therefore, the present study aimed to compare echocardiographic parameters in the study of right ventricular failure in patients with pulmonary hypertension. Materials and Methods: In the present descriptive cross-sectional study, data were col...
متن کاملRight ventricular diastolic impairment in patients with pulmonary arterial hypertension.
BACKGROUND The role of right ventricular (RV) diastolic stiffness in pulmonary arterial hypertension (PAH) is not well established. Therefore, we investigated the presence and possible underlying mechanisms of RV diastolic stiffness in PAH patients. METHODS AND RESULTS Single-beat RV pressure-volume analyses were performed in 21 PAH patients and 7 control subjects to study RV diastolic stiffn...
متن کاملAssessment of Right Ventricular Function by Newer Imaging in Echocardiography in Idiopathic Pulmonary Arterial Hypertension
Background The aims of the study were to assess the right ventricular (RV) functions in patients with idiopathic pulmonary arterial hypertension (IPAH) with RV longitudinal strain (RVLS) in addition to conventional parameters, as well as its correlation with severity and prognosis in IPAH. Methods Twenty-two IPAH patients were followed up for 1 year. ANOVA and Gabriel's pairwise comparison te...
متن کاملevaluation of right ventricular systolic function by echocardiography in pulmonary hypertension associated with congenital heart disease: a cross sectional study
background pulmonary arterial hypertension (pah) is a serious complication of unrepaired congenital left-to-right shunts. the final consequence is right ventricular (rv) systolic dysfunction and reversal of shunt. objectives the aim of this study was to evaluate the clinical course and paraclinical findings in a group of patients with pah associated with congenital heart disease (pah-chd). we a...
متن کاملRight Ventricular Myocardial Stiffness in Experimental Pulmonary Arterial Hypertension
BACKGROUND The purpose of this study was to determine the relative contribution of fibrosis-mediated and myofibril-mediated stiffness in rats with mild and severe right ventricular (RV) dysfunction. METHODS AND RESULTS By performing pulmonary artery banding of different diameters for 7 weeks, mild RV dysfunction (Ø=0.6 mm) and severe RV dysfunction (Ø=0.5 mm) were induced in rats. The relativ...
