Objective:
Atrial septal defect is a congenital heart disease usually diagnosed in childhood. This study aimed to evaluate the mid-term follow-up results of patients who underwent trans- catheter closure of atrial septal defect by comparing the devices and methods used in the procedure and investigating the complications of this procedure in children.
Materials And Methods:
This study evaluated 232 patient files retrospectively. Of the 232 patients, 24 were excluded from the study due to missing files or data. Also, patients with multi-fenestrated atrial septal defect and aneurismatic septal tissue were excluded from the study. The following data were evaluated: follow-up time, patient complaints, symptoms, trans- thoracic echocardiography, and transesophageal echocardiography findings (if performed), the size of the defect as measured by balloon-sizing, the size of the device used in the proce- dure, and major and minor complications.
Results:
The study included 208 children who were diagnosed with atrial septal defect. The mean age of the patients was 88.0 ± 56.5 months. Of the patients, 170 (81.7%) had no com- plaints. The success rate of the procedure was found to be 95.7%. While device embolization was the most common major complication, arrhythmia was the most common minor complica- tion. The complication rate was statistically different according to the device type used in the procedure.
Conclusion:
Transcatheter closure of atrial septal defect is a safe method for atrial septal defect closure in pediatric patients. The study found that defect diameters measured by differ- ent methods were not correlated with each other. The procedure complication rates differed according to device type.
