Objective: To investigate the clinical efficacy and value of Am platzer mushroom umbrella device for pediatric patent ductus arteriosus (PDA). Methods: A total of 68 patients aged 8 months to 12 years (average 6.4 years), weighing 6.5 to 30 (average 18.2) kg, PDA diameter of 3 ~ 8mm, intraoperative right venous catheter blood test, manometry , 5 ~ 15 mins after descending aorta angiography, measuring pulmonary arterial pressure, aortic pressure. After January, March and June, respectively, X-ray and echocardiography to understand whether the residual shunt and occluder position. Results: All the 68 patients were treated with Am platzer PDA mushroom prostheses with a success rate of 100%. The results were satisfactory and no complications were found. Echocardiography was performed on the third day after operation. No shunt occurred. Conclusion: The application of Amplatzer mushroom umbrella to treat PDA is less invasive, simple to operate, widely used, high success rate and satisfactory clinical efficacy
