Transhepatic device closure of large atrial septal defect.

Transcatheter closure of secundum-type atrial septal defects has become the treatment of choice in the majority of cases. Femoral venous access is the standard rout for device implantation. Anatomic abnormalities of venous system including interrupted inferior caval vein with azygous continuation can make the percutaneous procedure more complicated. In such instances, alternative methods of transjugular or transhepatic approach or surgical repair should be considered. We present the case of a 50-year-old male with secundum-type atrial septal defect and a rare form of segmental interruption of inferior caval vein and describe successful atrial septal defect closure through transfemoral approach.
