[Simultaneous treatment of pulmonary valve stenosis and patent ductus arterious by interventional catheterization].
The association of pulmonary valve stenosis and patent ductus arteriosus is uncommonly found in clinical practice of pediatric cardiology. The authors describe 2 patients with this association that were successfully treated in the same procedure by interventional cardiology: first case, a 14 month old boy was submitted to percutaneous pulmonary valvoplasty with reduction of systolic gradient between pulmonary artery and right ventricle from 71 to 3 mmHg. The 2.0 mm of diameter and conical shape duct was successfully occluded using a 38-5-5 coil; second case, a 20 month old girl was submitted to percutaneous pulmonary valvoplasty with reduction of systolic gradient between pulmonary artery and right ventricle from 60 to 5 mmHg. An attempt to close the 3.5 mm of diameter and concial shape duct using coil was performed, but the device embolized into the pulmonary artery. After immediate retrieval, a 12 mm Rashkind umbrella was implanted. Indication of treatment of both conditions, technical aspects and complications related to the procedures, and patients follow up are also discussed.
