Transthoracic echocardiography (TTE) is an important tool for diagnosis and follow-up of patients with congenital heart disease (CHD). Appropriate use TTE can reduce the need more invasive complex modalities, such as cardiac catheterization magnetic resonance imaging. New echocardiographic techniques have emerged assessment ventricular systolic diastolic function: Tissue Doppler imaging, tissue tracking, strain rate vector velocity imaging (VVI), myocardial performance index, acceleration during isovolumic contraction (IVA), ratio to duration (S/D ratio), other measurements right (RV) function like tricuspid annular plane excursion (TAPSE). These modalities may become valuable indicators performance, compliance progression, caveat preload-dependency variables measured. In addition, three-dimensional (3D) anatomy, valvular function, device position, volumes ejection fraction integrated into routine clinical care. this review, we discuss potential limitations these new in CHD. A particular focus on by means conditions associated increased volume or pressure load.
