OP-067 Assesment of Right Ventricular Function With Speckle Tracking Echocardiography After the Percutaneous Closure of ASD




Objective


Echocardiographic speckle tracking or two-dimensional (2D) strain analysis is a new tool to assess myocardial function. 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 evaluate longitudinal right ventricular (RV) function assessed using speckle-tracking strain echocardiography in patient with ASD before and 24 hours after percutaneous closure.




Methods


We prospectively examined 25 consecutive patients who underwent percutaneous transcatheter closure of secundum ASD from June 2013 to December 2015. Echocardiography was initially performed upon admission, prior to cardiac catheterization and then 24 hours after percutaneous transcatheter closure of secundum ASD.Right ventricular global longitudinal strains were measured by using speckle-tracking strain echocardiography in apical 4-chamber view (Figure 1).
