UNLABELLED Hepatic dysfunction is a recognized complication after Fontan palliation of congenital heart disease. We sought to quantitatively measure hepatic stiffness and vascular Doppler indices using ultrasound (US) and shear wave elastography (SWE) in a Fontan cohort. Subjects were prospectively recruited for echocardiography and real-time hepatic duplex(More)
BACKGROUND Left atrial (LA) function is an important modulator of left ventricular filling and has a prognostic role in adult heart failure, but pediatric data are limited. The aim of this study was to characterize the normal LA and right atrial (RA) strain (ε) and strain rate (SR) in infants and children. METHODS Atrial ε and SR were prospectively(More)
OBJECTIVES To investigate changes in fetal myocardial deformation in intrahepatic cholestasis of pregnancy. METHODS Patients with intrahepatic cholestasis of pregnancy were divided into 2 groups according to the total maternal serum bile acid concentration: mild cholestasis (10-40 μmol/L) and severe cholestasis (>40 μmol/L). Fetal echocardiography and(More)
AIM To investigate the value of ultrasonography (US) for diagnosing synovitis associated with rheumatoid arthritis (RA). METHOD Bilateral metacarpophalangeal (MCP), proximal interphalangeal (PIP) II-V and wrist joints of 46 RA patients and 35 healthy controls were evaluated by quantitative and semiquantitative US. Wrists on more severely affected sides of(More)
BACKGROUND Compromise of right heart function is an important feature of many forms of congenital heart disease, and right atrial (RA) pressure is clinically relevant. Inferior vena cava (IVC) diameter and inspiratory collapse are indices of RA pressure, but pediatric data are lacking. METHODS RA measurements, systemic venous diameters, and Doppler(More)
Precise quantification of left ventricular (LV) cavity dimensions assumes great importance in clinical cardiology. Pediatric guidelines recommend the left parasternal short axis (PSA) imaging plane for measuring LV cavity dimensions, while measuring from the long axis (PLA) plane is the convention in adult echocardiography. We sought to compare measurements(More)
OBJECTIVE To construct Z-score reference ranges for normal fetal heart sizes throughout pregnancy. METHODS This is a prospective cross-sectional investigation of 809 normal singleton fetuses from 11th week to term. Fetal transverse heart diameter (HD), heart length (HL), heart circumference (HC) and heart area (HA) were derived from two-dimensional(More)
OBJECTIVES Although transthoracic echocardiography is commonly performed in the PICU, its utility is not specifically known. The purpose of this investigation was to evaluate the clinical impact of echocardiography in the PICU in terms of frequency of unanticipated findings and the frequency and nature of clinical management changes attributed to the(More)
BACKGROUND Postnatal outcome of fetuses with hypoplastic left heart syndrome (HLHS) is mainly determined by right ventricular function. In the present study we used spatio-temporal image correlation (STIC) to assess right ventricular function of fetuses with HLHS. METHODS Three-dimensional ultrasound with STIC technique was used to acquire heart images(More)
OBJECTIVE To evaluate the superiority, feasibility and clinical signifi cance of the four-dimensional spatio-temporal image correlation (STIC) in detection of the right ventricle function of fetus. METHODS Th e STIC dynamic images of 180 normal fetal hearts at 24+0 to 37+6 weeks of gestation were obtained by the three-dimensional (3D) probe. Th e(More)
