[Percutaneous closure of atrial septal defect using transhepatic puncture].

The percutaneous closure of ostium secundum (OS) atrial septal defect (ASD) is a well-established procedure and is today considered the treatment of choice due to its good results and low morbidity and mortality. The procedure is routinely performed through the inferior vena cava (IVC). However, this route of access is not always available due to the obstruction or congenital absence of the IVC.
