Pulmonary 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 ...
متن کاملEvaluation 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 کاملEchocardiographic evaluation of pulmonary hypertension.
Echocardiographic studies of the pulmonary valve were obtained in 63 adults. Patients with normal pulmonary artery pressure (22 cases) showed an oblique position of the valve images in diastole, slow valve opening slopes (< 300 mm/see), sizable (> 2 mm) posterior displacement of the cusp echoes with atrial systole ('a' dip), and a relatively short right ventricular pre-ejection period. In contr...
متن کاملSex and Hemodynamics in Pulmonary Arterial Hypertension
Introduction: Female sex is a risk factor for pulmonary arterial hypertension (PAH), yet women have better survival than men. We sought to determine if sex was associated with baseline hemodynamics in subjects with PAH, and whether age modified these relationships. Material and Methods: We conducted a pooled analysis from 11 randomized trials submitted to the U.S. Food and Drug Administration. ...
متن کاملEchocardiographic assessment of pulmonary vascular resistance in pulmonary arterial hypertension
BACKGROUND Echocardiographic ratio of peak tricuspid regurgitant velocity to the right ventricular outflow tract time-velocity integral (TRV/TVI rvot) was presented as a reliable non-invasive method of estimating pulmonary vascular resistance (PVR). Studies using this technique in patients with moderate to high PVR are scarce. Left ventricular outflow tract time-velocity integral (TVI lvot) can...
