Transcatheter closure of a large ASD from the femoral vein in a patient with Budd-Chiari syndrome.

Anomalies of the inferior vena cava are rare in patients with isolated atrial septal defect (ASD). When present, they usually preclude successful transcatheter closure of the ASD using the femoral route. We report a case of a large secundum ASD in a 3-year-old child, who had a chronic Budd-Chiari syndrome incidentally detected on the cardiac catheterization table. We were able to successfully deploy the device from the femoral route itself using a collateral channel to reach the heart and then using the pulmonary vein deployment technique to successfully close the defect.
