RESULTS OF TRANSVENOUS BUTTONED DEVICE OCCLUSION OF PATENT DUCTUS-ARTERIOSUS IN ADULTS

Examination of the immediate and follow-up results of tranvenous butto ned device occlusion of patent ductus arteriosus suggests that the met hod is feasible, safe, and effective irrespective of the size and shap e of the ductus. Although residual shunts are present, they tend to di sappear during follow-up, and complete occlusion at the time of implan tation may be achieved by incorporation of a folding plug over the but ton loop of the device.
