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)
We sought to determine whether global and regional left ventricular (LV) strain parameters were altered in repaired coarctation of the aorta (COA) with normal LV ejection fraction (EF) when compared with healthy adult controls, and whether such alterations were related to LV hypertrophy (LVH). We identified 81 patients after COA repair (31 female, age 25 ±(More)
With increasing applications of cardiac magnetic resonance (CMR) and magnetic resonance angiography (MRA) for evaluation of congenital heart disease (CHD), safety of this technology in the very young is of particular interest. We report our 10-year experience with CMR in neonates and small infants with particular focus on the safety profile and incidence 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)
We investigated intermodality agreements of strains from two-dimensional echocardiography (2DE) and cardiac magnetic resonance (CMR) feature tracking (FT) in the assessment of right (RV) and left ventricular (LV) mechanics in tetralogy of Fallot (TOF). Patients were prospectively studied with 2DE and CMR performed contiguously. LV and RV strains were(More)
The relationship between sinonasal disease and septal deriations is well known, albeit vaguely. There was no serious attempt to classify deviations except calling them mild deviations, gross deviations, spur; high deviations, etc. The airflow changes in these deviations, which lead to mucosal changes predisposing to polyps or infection have not been(More)
Methods Clinical, anesthesia and nursing records of all patients (pts)<120 days of age who underwent CMR were reviewed. Variables including cardiac diagnosis, study duration, anesthesia type and agents used, prostaglandin E1 (PGE1) dependence and gadolinium (Gd) use were recorded. Serially recorded temperature, systemic saturation, and cardiac rhythm were(More)
