Right Heart Catheterization Datas May Not Reflect The Pulmonary Hypertension Epidemiology Accurately
Methods Research subjects included 10 normal volunteers undergoing CMR and 36 patients undergoing clinically indicated right and left heart catheterization and a research CMR within 5 hours. Cine images were acquired to evaluate RV volumes and RVEF. Radial and longitudinal RV segmental displacement during systole were evaluated at the right sided septal endocardium and RV free wall on 4-chamber...
Pulmonary arterial hypertension is a progressive and fatal disease rodents with experimental pulmonary (PH) are often used to study pathogenic mechanisms, identify therapeutic targets, develop novel drugs for treatment. Here we describe hands-on set of approaches including ex vivo lung angiography histology in right heart catheterization (RHC) phenotypically characterize hemodynamics vascular s...
No data are available on determining right atrial and right ventricular size by two-dimensional echocardiography. We performed two-dimensional echocardiograms on eight human right-heart casts obtained at autopsy and on 50 patients who underwent complete left- and right-heart catheterization. Measurement of individual dimensions of the long and short axes of the right atrium and ventricle from r...
PURPOSE We aimed to determine the correlation between flow characteristics of the proximal pulmonary arteries and vena cava obtained by 3.0 T phase-contrast magnetic resonance imaging (MRI) and hemodynamic characteristics by right heart catheterization in patients with chronic thromboembolic pulmonary hypertension. MATERIALS AND METHODS Twenty consecutive patients with chronic thromboembolic ...
