Imaging right ventricular function to predict outcome in pulmonary arterial hypertension.
BACKGROUND Right ventricular (RV) function is a major determinant of outcome in pulmonary arterial hypertension (PAH). However, uncertainty persists about the optimal method of evaluation. METHODS We measured RV end-systolic and end-diastolic volumes (ESV and EDV) using cardiac magnetic resonance imaging and RV pressures during right heart catheterization in 140 incident PAH patients and 22 c...
متن کاملAssessment of Right Ventricular Function by Newer Imaging in Echocardiography in Idiopathic Pulmonary Arterial Hypertension
Background The aims of the study were to assess the right ventricular (RV) functions in patients with idiopathic pulmonary arterial hypertension (IPAH) with RV longitudinal strain (RVLS) in addition to conventional parameters, as well as its correlation with severity and prognosis in IPAH. Methods Twenty-two IPAH patients were followed up for 1 year. ANOVA and Gabriel's pairwise comparison te...
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 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 کاملRight Ventricular Myocardial Stiffness in Experimental Pulmonary Arterial Hypertension
BACKGROUND The purpose of this study was to determine the relative contribution of fibrosis-mediated and myofibril-mediated stiffness in rats with mild and severe right ventricular (RV) dysfunction. METHODS AND RESULTS By performing pulmonary artery banding of different diameters for 7 weeks, mild RV dysfunction (Ø=0.6 mm) and severe RV dysfunction (Ø=0.5 mm) were induced in rats. The relativ...
