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 کاملShape of the right ventricular outflow Doppler envelope and severity of pulmonary hypertension.
BACKGROUND It is now well known that timing of right ventricular outflow tract (RVOT) spectral Doppler signals change with increasing pulmonary hypertension severity. We devised a study to determine whether visual assessment of these RVOT Doppler signals can be useful identifying the severity of pulmonary hypertension. METHODS Visual inspection of pulsed RVOT Doppler signals from 120 consecut...
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 کاملApplication of centrifugal pump in right ventricular failure due to pulmonary artery hypertension. (A case report)
Background: It has not been yet developed a ost suitable method to treat right ventricular failure due to pulmonar artery hypertention resulted from ventricular arrhythia. Though some case reports about patients ready to heart transplant using left assist device or biventral assist device as bridge have been published in Journals, but nocase concerning application of centrifugal pump for treatm...
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...
