Objective: To evaluate the result of transcatheter closure of the patent ductus arteriosus (PDA) with coils.

Methods: Coil occlusion of PDA through transarterial approach was attempted in 64 consecutive patients (male 16, female 48; age: mean 6.6 years, range 7 months to 48 years; body weight: mean 18.6 kg, range 5.3 to 58.5 kg ). The ductal diameter ranged from 0.1 mm to 4.9 mm with mean of 2 mm. The systemic to pulmonary flow ratio ranged from 1.01 to 4.9, with mean of 1.41. The results were evaluated by angiography at 10 minutes and by color Doppler echocardiography at 1 day, 1 week, 1 month, 3 months, 6 months and 12 months after the procedure.

Results: The total occlusion rates were 78.1%, 87.5%, 90.6%, 93.8%, 95.3%, 95.3% and 95.3% at 10 minutes, 1 day, 1 week, 1 month, 3 months, 6 months and 12 months respectively.

Conclusions: Transcatheter closure of PDA with coils is a safe and effective method.
