Introduction: Speckle tracking echocardiography (STE) for two-dimensional (2D) strain analysis
is a new tool to assess myocardial function. The aim of this study was to assess right atrial (RA)
function using STE in patients with an atrial septal defect (ASD) before and one month after
percutaneous closure.
Methods: We prospectively examined 32 consecutive patients (nine male, 23 female) who
underwent percutaneous transcatheter closure of a secundum ASD between June 2013 and
December 2015. Echocardiography was performed on admission, prior to cardiac catheterization and then one month after ASD closure. Peak global RA longitudinal strain was analyzed by
2D-STE.
Results: Patients’ mean age was 34.6±8.2 years. The mean diameter of the occlusive devices
was 18.5±7.5 mm. Right ventricular (RV) end-diastolic diameters were significantly increased
but decreased significantly after ASD closure (43±5 vs. 38±4 mm, p<0.05). Left atrial (LA)
diameters (40±8 vs. 37±6 mm, p<0.05) decreased significantly after the intervention, whereas
left ventricular (LV) end-diastolic diameters (45±5 vs. 46±4 mm, NS) remained unchanged.
Tricuspid annular plane systolic excursion increased significantly (17.6±5.4 vs. 22.3±8.1 mm,
p<0.05). After closure of the defect, a significant increase was observed in longitudinal RA strain
(26.5±9.6% vs. 35.3±10.5%, p<0.001).
Conclusions: After percutaneous transcatheter closure of a secundum ASD, there was an
increase in RA longitudinal strain. 2D-STE strain analysis appears to be helpful for the assessment of RA function and of response to correction of volume overload after percutaneous
transcatheter closure of a secundum ASD.
