Echocardiographic evaluation of pulmonary hypertension by oxygen inhalation method.
The ratio of the right ventricular preejection period to the right ventricular ejection time was calculated from the echocardiogram of the pulmonic valve before and after inhalation of a high concentration of oxygen in pulmonary hypertensive patients. The results showed that this non-invasive method could differentiate pulmonary vascular disease from non-pulmonary vascular disease and hence use...

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 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 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 ...
متن کاملEvaluation of Pulmonary Hypertension In First Degree Relatives Of Patients With Primary Pulmonary Hypertension
Background: Pulmonary hypertension (PH) was defined for the first time in 1951 as primary pulmonary hypertension (PPH). Some studies emphasized on the role of genetics in the development of pulmonary hypertension in family members of affected patients. So, in this study we evaluated the prevalence of pulmonary hypertension in first degree family of patients with documented PPH. Methods: In thi...
