Background Right ventricular (RV) function is an important determinant of mortality in patients with idiopathic pulmonary arterial hypertension (iPAH). The aim of this study was to serially evaluate global and…
Background In children, there is limited information regarding the relative contribution of left ventricular (LV) apical and basal rotation to increase LV pump function with exercise. The aim of this…
Background Patients with repaired tetralogy of Fallot often present residual hemodynamic abnormalities leading to right ventricular (RV) burden. Semisupine exercise echocardiography (Ex-Echo) is a validated method for diagnosis and prognosis…
Background Patients with Kawasaki disease (KD) are at risk for developing coronary artery lesions, but the association of noncoronary changes such as mitral regurgitation (MR) and/or pericardial effusion (PE) with…
Background The purpose of this investigation was to test the hypothesis that flow patterns in the right ventricle are abnormal in patients with repaired tetralogy of Fallot (TOF). High-resolution echocardiographic…
Background Novel echocardiographic techniques based on myocardial deformation have not been extensively evaluated to assess right ventricular (RV) and left ventricular (LV) response after pulmonary valve replacement (PVR) in patients…
Background There is a paucity of echocardiographic data describing right ventricular (RV) dimensions and function in the early transitional newborn period. Methods Fifty healthy term newborns underwent serial echocardiography at…
Background Although a quantitative evaluation of cardiac chamber dimensions in pediatric echocardiography is often important, nomograms for these structures are limited. The aim of this study was to establish reliable…
The purpose of scaling organ dimensions is motivated by the possibility of comparing individuals of different body sizes, a potent determinant of organ size. This is useful in comparative physiology,…
Background Accurate normalization of cardiac chamber size in the obese population is a challenge. The aim of this study was to develop and assess the performance of allometric models for…
