Background Diastolic dysfunction is considered the first marker of diabetic cardiomyopathy. However, preclinical systolic alteration was also recently described by strain, but its association with diastolic dysfunction has never been…
Background Mitral repair is recommended for patients with significant organic mitral regurgitation (MR). The nonresectional dynamic mitral valve repair (NVR) method involves a complete flexible ring and artificial chordal insertion…
Background The purpose of this study was to investigate whether global longitudinal strain measured by two-dimensional speckle tracking echocardiography could detect incipient myocardial dysfunction in patients with chronic aortic regurgitation…
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…
