ABSTRACT
Atrial septal defect (ASD) is one of the most common congenital heart defects. Transcatheter device closure of ASDs is safe and effective with most of the reported data being described from developed countries. To evaluate the short and mid-term results and experience of device closure of ASDs at a tertiary center in a developing country and compare it to that from developed countries. Retrospective study based on data collection from all patients who have undergone transcatheter percutaneous device closure for ASD from January 2005 until December 2017 at the Children's Heart Center at the American University of Beirut, Medical Center, Lebanon. During the study period, a total of 254 cardiac catheterizations were performed for device closure of ASDs. The mean age of the patients was 18 ± 17.9 years with 37% being less than 6 years of age. Females were 54%. Defect size ranged from 7 to 37 mm and device size ranged from 8 to 40 mm. The procedure was executed with a success rate of 96%. Five patients had device embolization (2%); in one patient the device was snared and for the remainder the devices were removed surgically. None of the study patients had thrombus formation, neurological complications, bacterial endocarditis, or cardiac erosions. There was no mortality. Device closure of ASDs at our tertiary center in a developing country has an effective and safe profile with excellent results and low complications rates, which compare favorably to those reported from centers in developed countries.
