Echocardiographic evaluation of pulmonary hypertension by oxygen inhalation method.
نویسندگان
چکیده
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 useful for evaluating the change of the pulmonary vascular bed in the pulmonary hypertensive patients.

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 کاملAcute hemodynamic effect of inhaled iloprost in pulmonary artery hypertension evaluated with echocardiography
Doppler echocardiography is useful in the initial evaluation and long-term follow-up of patients with pulmonary artery hypertension. Aerosolised iloprost has been shown to reduce pulmonary pressure immediately after inhalation. We report the echocardiographic findings in a patient with severe pulmonary hypertension, before and after the inhalation of aerosolized iloprost. These findings illustr...

1. Technology Assessment Nitric Oxide inhalation (iNO) therapy is a noninvasive treatment for PPHN that involves inhalation of gaseous nitric oxide in conjunction with ventilator support. The potential of exogenous NO as a therapeutic agent is based on its potent vasodilator properties and its ability to be delivered as a gas to the lung. Exogenous NO increases the partial pressure of arterial ...
متن کاملRole of Transthoracic Echocardiography in the Evaluation of Patients with Retinal Vein Occlusion
Introduction: Retinal vein occlusion is a common vascular disorder disrupting vision. Two basic types of RVO are branch retinal vein occlusion and central retinal vein occlusion (CRVO). Retinal vein occlusion is a multifactor process including systemic illness and local retinal factors.RVO may be associated with atherosclerotic risk factors. We analyzed the role of 2 dimensional transthor...

A 13 months male child presented with progressive dyspnea of three months and recent cyanosis. Cardio-respiratory examination revealed tachypnea, cyanosis, left parasternal heave and loud P2. Echocardiography revealed thrombus in pulmonary artery and severe pulmonary arterial hypertension. Tests for throbmophilia demonstrated protein S deficiency. Treatment included anticoagulants, sildenafil, ...
