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.

Techniques for performing the Fontan completion procedure after Kawashima procedure have developed in recent years. This paper presents a case in which we performed an off-pump hepatic-to-azygos connection by autologous pericardial roll via thoracotomy as a modified Fontan completion. The operation wound was limited, and the short-term follow-up was satisfactory. Notably, it was found that the autologous pericardium might require a shorter period of anticoagulation treatment than what is needed for artificial prosthetic materials.

We report a girl, aged 11 years, who presented with cyanosis. Cardiac catheterization showed occlusion of the infrahepatic segment of the inferior caval vein, with drainage of the hepatic veins into the left atrium. Transoesophageal echocardiography revealed an anomalous Eustachian valve that baffled the vein to the left atrium. This lesion is an extremely rare cause of cyanosis.
