Right Atrial Function in Pulmonary Arterial Hypertension.
BACKGROUND Elevated right atrial (RA) pressure is an established prognostic measure in pulmonary arterial hypertension (PAH). However, little is known about perturbations in RA function in PAH. METHODS AND RESULTS Reservoir (RA longitudinal strain [RA LS]), conduit (RA early LS rate), and active (RA late LS rate) phases were assessed by 2D speckle tracking in 65 patients with PAH, 6-minute wa...
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 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 hemodynamics and right ventricular function in hypertension.
Pulmonary and systemic hemodynamics in 16 hypertensive subjects (group I) with left ventricular (LV) hypertrophy (ECG and echo criteria) and in 17 hypertensive subjects with ECG signs of LV strain (group II), were compared with those in 14 normal individuals. An augmented pulmonary arteriolar resistance (PAR) in group I and to a larger extent in group II accounted for the pulmonary pressure ele...
متن کاملAssessment of Right Ventricular Structure and Function in Pulmonary Hypertension
Right ventricular function plays an important role in determining cardiac symptoms and exercise capacity in chronic heart failure. It is known that right ventricle has complex anatomy and physiology. The purpose of this review paper is to demonstrate the best assessment of the right ventricle with current echocardiography. Echocardiography can assess sufficiently right ventricular structure and...
