[The transcatheter closure of the persistent ductus arteriosus in an adult].

Transcatheter closure of a patent ductus arteriosus was successfully performed in a symptomatic 48-year-old man. Pulmonary to systemic flow ratio was of 2.8:1 and ductus arteriosus closure was carried out percutaneously, using a 17 mm. Rashkind umbrella. One month later, the patient presented a significant clinical improvement and there also was a reduction of the left ventricle dilatation, objectively assessed by two-dimensional echocardiography.
