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 transcatheter 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, transthoracic 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 procedure, 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 complaints. 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 complication. 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 different methods were not correlated with each other. The procedure complication rates differed according to device type. [ABSTRACT FROM AUTHOR]

We reviewed all cases of primary pediatric mediastinal masses diagnosed and treated over a 24-year period. In this study, out of 187 primary mediastinal mass cases diagnosed between 1980 and 2004 in Istanbul University Istanbul Faculty of Medicine, Cardiovascular Surgery Department, 37 pediatric primary mediastinal mass cases were retrospectively evaluated according to age, sex, symptoms, diagnostic procedure, anatomical location, surgical treatment, histopathological evaluation and postoperative adjuvant therapy. The patients ranged in age from 2 months to 15 years at the time of diagnosis, with a mean age of 8 years. There were 24 benign (64.8%) and 13 malignant (35.2%) tumors. The cases were lymphoma (27%), neurogenic tumors (21.6%), cystic lesions (18.9%), germ cell tumors (13.5%), thymic lesions (10.8%) and cardiac tumors (8.1%). Complete and partial resections of the tumor were the surgical procedures performed in 24 patients (64.8%) and 3 patients (8.1%), respectively. The three patients with a malignant tumor, in whom the entire mass could not be removed, received chemotherapy and radiation after surgery. In 10 patients with lymphoma, surgery was not a part of treatment and they received medical and radiation therapy after the establishment of the definitive diagnosis. All patients survived and were discharged from the hospital. Except for the cases with lyphoma, all patients are now free of recurrent disease. Compared to adults, children had more lymphomas and neurogenic tumors. Primary pediatric mediastinal malignancies are relatively common in infants and children. Lymphoma, neurogenic tumors and cystic lesions predominated. These differences between the age groups should also be considered when dealing with a mediastinal mass.
