months (range, 3–21 months), and all patients were reviewed at 1 month. All 18 devices were successfully implanted. All patients were discharged 24 hours fol- lowing the procedure, and complete PDA occlusion on Doppler echocardiography was achieved in all but two patients (closure rate, 90%). At 1-month fol- low-up, all patients had total duct occlusion on Dop- pler echocardiography (closure rate, 100%).
Successful device placement rate was 100%. There were no mortalities or major complications. Aortic disc bulging occurred in two patients without hemo- dynamic gradient. Mild pulmonary obstruction was noted in one patient in whom the long device variant
was used. A cardiac ultrasound at 6-month follow-up did not show evidence of hemodynamic gradient. No blood transfusions were needed. No hemolysis oc- curred. There were no femoral vascular complications.
Discussion
PDA Treatment
PDA is a common congenital heart defect usually identi ed in early childhood. In some cases, it remains unrecognized until late in life. Currently, percutane- ous closure of almost any PDA beyond neonatal age using detachable coils or speci cally designed oc-
