Abstract: Objective To analyze clinical outcomes of interventional therapy for common congenital heart diseases (CHD). Methods We retrospectively analyzed the clinical records of 57 patients with CHD who underwent catheter interventional therapy in People’s Hospital of Deyang City between March 2009 and January 2012. There were 31 male patients and 26 female patients with their mean age of 29.4±3.5 years(ranging from 1.5 to 75.0 years). There were 21 patients with patent ductus arteriosus (PDA), 12 patients with ventricular septal defect (VSD), and 20 patients with atrial septal defect(ASD);and 2 patients with VSD plus ASD, 1 patient with VSD plus PDA, and 1 patient with ASD plus PDA. Occluder and supplying system made in China were used in the interventional therapy. For the patients with ASD plus PDA, PDA was blocked before ASD;for the patients with VSD plus PDA, PDA was blocked before VSD;and for the patients with VSD plus ASD, VSD was blocked before ASD. Results The duration of interventional therapy ranged from 30 to 90 minutes. The success rate of operation was 98.3%(56/57). Operation was given up in an old female patient with ASD and chronic obstructive pulmonary disease because of pulmonary hypertension. The hospital stay was 3 -7 days. All the patients were followed up at the outpatient department for 1 month to 2 years by color Doppler echocardiogram, chest X-ray and electrocardiograph, and no complication occurred during follow-up. Conclusion With complete understanding of surgical indications and strict compliance with procedures, catheter interventional therapy is safe, minimal invasive, and effective in CHD treatment.
