Two‐Dimensional Strain and Strain Rate Imaging of the Left Atrium and Left Ventricle in Adult Patients with Atrial Septal Defects before and after the Later Stage of Percutaneous Device Closure

Abstract

LA and LV S and SR are not significantly affected in ASD patients. However, correction of the long-standing volume overload by percutaneous closure causes an early increase in LA and LV longitudinal deformation that correlates with the magnitude of the atrial septal defect. But this increase decreased in 1 month after closure.

Assessment of the Right and Left Atrial Functions at Midterm After Surgical and Device Atrial Septal Defect Closure: A 2‐Dimensional Speckle‐Tracking Echocardiographic Study

“…The continuation of the remodeling effect of previous ASD shunting may be another possible explanation . Furthermore, we found that an impaired LA reservoir and conduit function and an impaired RA contraction function were more probable in our patients who underwent device ASD closure, which is concordant with some previous research . The presence of a device anchoring on an atrial wall without deformation of any magnitude may lead to decreased longitudinal deformation in the other walls.…”

“…Cakal et al compared the LA functions as assessed with 2D speckle‐tracking echocardiography between 20 adult patients with ASD who were candidates for device ASD closure and 20 healthy participants. They reported that before closure, the LA functions were not different between their groups; nonetheless, 24 hours after closure, all of the LA functions were increased, and at 1 month, the peak systolic strain (the index of the reservoir function) was increased, whereas the peak systolic strain rate, early diastolic strain rate, and late diastolic strain (the indices of the reservoir, conduit, and contraction functions of the LA, respectively) were reduced compared with the preclosure values.…”

“…Research on the function of the heart chambers in patients with ASDs in comparison with healthy control individuals has shown impairment in the former group . The recovery of function in the cardiac chambers after these treatment modalities is assessed with echocardiography . The functions of the right atrium (RA) and the left atrium (LA) after ASD closure have been previously investigated, but most of these studies had maximal follow‐up durations of only 1 year .…”

“…The recovery of function in the cardiac chambers after these treatment modalities is assessed with echocardiography . The functions of the right atrium (RA) and the left atrium (LA) after ASD closure have been previously investigated, but most of these studies had maximal follow‐up durations of only 1 year . In addition, not only have these studies reported conflicting results, but also some of them compared the atrial functions before and after ASD closure without control participants .…”

“…Previous studies drawing on color‐coded tissue Doppler echocardiography in patients with ASDs evaluated the atrial functions only in a single segment of the atrial walls . Two‐dimensional speckle‐tracking echocardiography has been used for the evaluation of the atrial functions in some congenital heart diseases such as pulmonary atresia, ASDs, coarctation of the aorta, and tetralogy of Fallot . There is a dearth of data in the current literature on the comparison of the atrial functions between surgical and percutaneous device ASD closure at follow‐up durations of longer than 1 year.…”
