Abstract/OtherAbstract:
AIM: Atrial septal defect (ASD) causes chronic volume overload of the right heart. The potential adverse effects of this long-standing volume overload to left atrium (LA) and left ventricle (LV) and their response to ASD closure has been poorly studied.
METHODS: We studied 20 ASD patients before the procedure, at the 24-hour and 1 month following the percutaneous closure. Twenty age-matched controls served as the control group. The analysis for atrial deformation was performed on the lateral wall, mid segment of the LA from apical four-chamber view. Peak longitudinal strain (S) and strain rate (SR) during LA reservoir, passive emptying, atrial contraction phases and LV global longitudinal systolic S and SR were measured.
RESULTS: Peak S and SR at LA reservoir, conduit and late contraction phases in ASD patients were similar to controls. All of these parameters increased immediately after the closure of the defect. Similarly, SLV and SRLV in ASD patients were not significantly different from the controls and significantly increased after the closure. But LA S, SR and LV S, SR results decreased in 1 month after the closure. SLV in ASD patients was significantly correlated with echocardiographic findings and the invasively measured defect size.
CONCLUSION: 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.
