The effect of operation and the effect of the imposition of an occluding device on atrial
function for patients with an atrial septal defect (ASD) has never been studied. Thus, the aim …

For the first time, peak systolic strain and strain rate (SR) were used to assess right
ventricular (RV) and left ventricular (LV) regional function in children after transcatheter and …

Objective: To compare the effects of surgical and device closure of atrial septal defects on
atrial and ventricular performance assessed by the novel tissue Doppler derived strain rate …

Background: Quantitative assessment of the right ventricular (RV) function in atrial septal
defect (ASD) patients before and after closure remains difficult. The aim of this study was to …

To evaluate acute change of right and left ventricle after percutaneous closure of isolated
atrial septal defect (ASD) 21 adult patients (13 F; 8 M) aged 28±9.5 range 18–49 years have …

Aims Atrial septal defect (ASD) is one of the most common congenital heart diseases in
adults. We prospectively evaluated early and mid-term effects of the percutaneous closure of …

Investigate ventricular and atrial remodeling following atrial septal defect (ASD) closure and
examine if pulmonary-to-systemic flow ratio (QP/QS) and right ventricular (RV) volume …

Abstract Real-time three-dimensional (3D) echocardiography allows us to measure right
ventricular (RV) end-diastolic volume irrespective of its shape. Tissue Doppler imaging (TDI) …

This study examined the influence of preload alterations on systolic right ventricular (RV)
velocities and deformation indices in patients with atrial septal defect (ASD). A total of 21 …

Aims Echocardiographic speckle tracking or two-dimensional (2D) strain analysis is a new
tool to assess myocardial function. This prospective controlled study evaluates systolic right …
