Systemic venous diameters, collapsibility indices, and right atrial measurements in normal pediatric subjects.

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 filling fractions were prospectively investigated in healthy volunteer children and adolescents.

Functional maturation of left and right atrial systolic and diastolic performance in infants, children, and adolescents.

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 investigated in 153 subjects using two-dimensional speckle-tracking echocardiography.

Echocardiography and cardiac magnetic resonance-based feature tracking in the assessment of myocardial mechanics in tetralogy of Fallot: an intermodality comparison.

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 computed separately using 2DE and CMR-FT.

Safety of cardiac magnetic resonance and contrast angiography for neonates and small infants: a 10-year single-institution experience.

Background: 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.

Objective: We report our 10-year experience with CMR in neonates and small infants with particular focus on the safety profile and incidence of adverse events (AEs).

Materials And Methods: We reviewed clinical, anesthesia and nursing records of all children ≤120 days of age who underwent CMR.

Reduced global longitudinal and radial strain with normal left ventricular ejection fraction late after effective repair of aortic coarctation: a CMR feature tracking study.

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 ± 8.5 years) with inclusion criteria at follow-up CMR of: age ≥13 years, time post-repair ≥10 years, no aortic valve disease, LV-EF >50%).
