Background Recent studies have emphasized the importance of quantitative assessment of the degree of aortic regurgitation (AR). However, semiquantitative methods have remained mainly used despite their unclear diagnostic value. The…
Background The purpose of this study was to investigate changes in right ventricular (RV) function and deformation parameters before and at steady state after the Norwood operation in neonates with…
In North America, approximately 10,000 isolated primary mitral valve (MV) operations are performed annually, with increasing rates of MV repair. There are substantial advantages of MV repair compared with MV…
Background Elevated ventricular filling pressure is a marker of diastolic dysfunction and a known risk factor for failure of single-ventricle surgical palliation. Doppler echocardiography has been shown valuable in identifying…
Background The aim of this study was to evaluate functional differences between the left and right sides of the ventricular septum in children with right ventricular overload. Methods Radial, longitudinal,…
Background Complex anatomy and limited windows complicate echocardiographic assessments of ventricular function in Fontan patients. For the Pediatric Heart Network Fontan Cross-Sectional Study, data were acquired from which mean ventricular…
Background The accurate assessment of right ventricular (RV) function and dimensions has important prognostic implications in patients with repaired tetralogy of Fallot (ToF). Three-dimensional imaging is the preferred methodology to…
Background Early results of tetralogy of Fallot (TOF) surgical repair are excellent, but patients are at risk for long-term complications. The purpose of the study was to determine to what…
Background Assessment of right ventricular (RV) volumes and function is important in patients after tetralogy of Fallot (TOF) repair. Currently, cardiac magnetic resonance imaging (MRI) is considered the clinical reference…
Background The aim of this study was to demonstrate improvement in the characterization of diastolic function in the routine practice of a clinical echocardiography laboratory after the implementation of a…
