Abstract

Objective: Atrial septal defect (ASD) is the most common congenital heart disease in adults and is evaluated by cardiac magnetic resonance (CMR) imaging. This study aimed to evaluate CMR results in ASD cases and to investigate ASD diameter and cardiac functional change.

Methods: Forty-two adult patients diagnosed with ASD in CMR were evaluated retrospectively. Cases were assessed by the right atrium (RA), right ventricular (RV) end-diastolic diameter (ED), left ventricle (LV) ejection fraction (EF), and ASD maximum diameter. After the Kolmogorov-Smirnov normality test, cases were compared with the paired Student’s t-test, and non-parametric variables were compared with the Mann-Whitney test. The effect of the ASD diameter on the RVEF, LVEF, and RAED, RVED was investigated using Pearson’s correlation coefficient.

Results: Low correlation was found between ASD diameter and RVEF (r=0.369), LVEF (r=0.329). A medium correlation was found between ASD diameter and RVED size (r=0.511). The highest correlation was found between ASD size and RAED diameter (r=0.54). The ASD diameter was found to be correlated with the deterioration in the right heart and LV functions.

Conclusion: CMR is an important examination in obtaining morphological and functional data in ASD cases. changes in heart function observed in patients significantly correlated with ASD.
