Introduction .– It is well known that right ventricular pacing (VP) can alter left ventricular (LV) function. But few are known in ability of LV recovery after VP. Objectives .–…
Introduction .– The biplane Simpson remains the gold standard for the evaluation of left ventricular ejection fraction (LVEF). However, it allows only a semi-quantitative assessment of the myocardial function without…
Purpose .– To assess left ventricular (LV) twist mechanics in patients (pts) with tako-tsubo syndrome (TTS). Methods .– Two-dimensional strain and LV twist by speckle tracking echocardiography (echoPACK 7 version…
Aim .– Right ventricular (RV) function is a major determinant of prognosis in patients (pts) with congenital heart diseases (CHD), but its evaluation remains challenging. We evaluate feasibility and reproducibility…
Objectives .– To study the feasibility of quantifying left ventricular (LV) function by 2D-speckle tracking of myocardial deformation during exercise echocardiography in normal subjects. Background .– Accurate assessment of LV…
Introduction .– Stroke volume (SV-ETT) is hitherto evaluated by transthoracical Doppler (TTE) as: (circular) cross sectional area(CSAO) × velocity time integral (VTI). Cardiac output (CO) can thereof be derived as:…
Background .– Right ventricular (RV) function is a major determinant of prognosis in patients (pts) with operated tetralogy of Fallot (ToF), but its evaluation remains challenging. We compared results from…
Background .– Bicuspid aortic valve (BAV) is the most common congenital heart defect. Children with BAV are more likely to have valve dysfunction and to require intervention during childhood. According…
Background .– Two-dimensional (2D) speckle tracking echocardiographic strain analysis has demonstrated good capacities in the quantification of left ventricular (LV) contraction but it is limited by LV geometric modelling and…
