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 کاملEvaluation of right ventriculoarterial coupling in pulmonary hypertension: a magnetic resonance study
Methods We included 139 patients undergoing CMR and right heart catheterization within 2 days (n=151 test pairs) for the evaluation of known or suspected pulmonary hypertension. Right ventricular end-systolic volume index (ESVI) and stroke volume index (SVI) were obtained, respectively, from cardiac cine images and phasecontrast of the pulmonary artery after adjusting for body surface area. Rig...
متن کاملClinical value of echocardiographic Doppler-derived right ventricular dp/dt in patients with pulmonary arterial hypertension.
AIMS Right ventricular (RV) dp/dt is the instantaneous rate of RV pressure rise during early systole and is a surrogate marker of RV contractility. The main objective of this study was to evaluate the ability of echocardiographic Doppler obtained RV dp/dt to predict long-term survival in patients with pulmonary arterial hypertension (PAH) and chronic thrombo-embolic pulmonary hypertension (CTEP...
متن کاملwhich type of right ventricular pressure overload is worse? an echocardiographic comparison between pulmonary stenosis and pulmonary arterial hypertension
conclusions it seems that severe pah aggravates the rv function more severely. results significant tricuspid regurgitation was more prevalent in the pah group than in the ps group (61% vs. 18.5%; p < 0.001). the abnormalities in the rv myocardial performance index, rv areas, and rv fractional area change were significantly more robust in the pah group (all ps < 0.05) despite the higher net rv s...
متن کاملPulmonary hypertension: echocardiographic assessment.
Pulmonary arterial hypertension (PAH) is a clinical condition characterized by elevated vascular resistance, associated with a poor prognosis and usually diagnosed in late stage. Echocardiographic assessment of PAH includes early disease detection and functional heart evaluation, in order to introduce a more accurate surveillance at an early stage of the disease and to contribute to prognostic ...
