The result of endovascular surgical treatment of congenital heart disease Background: Over the last 10 years the advances in catheter based interventions for congenital heart disease(CHD) include new procedures, devices and almost 25% of all CHD are now can be treated by endovascular surgery. The purpose of this report was to evaluate the outcome and result of endovascular surgeries for congenital heart disease. Materials and methods: The study included all cases of endovascular surgeries at the National Center for Maternal and Child Health the period of 2014-2019. Results: Total 631 cases had intervention procedures and 377 (59.7%) cases had endovascular surgeries for CHD. 268 patients had patent ductus arteriosus device closure successfully while 57 had pulmonary artery valvuloplasty using balloons. Also 76 patients had device closure of atrial septal defect and 4 patients had device closure of ventricular septal defect using new multifunctional occluder. Another 20 patients had severe coarctation of aorta and had balloon dilatation and stenting as a life saving procedure. Conclusions: Endovascular surgery for CHD is a safe and effective alternative to open heart surgery.
