Transcatheter Approach for Fontan Failure due to Ventricular Volume Overload

Transcatheter Approach for Fontan Failure due to Ventricular Volume Overload

Systemic ventricle volume overload is an uncommon cause of failure of Fontan circulation. It may be due to ventricular valve malfunction or residual forward flow to pulmonary circulation. In selected cases, interventional cardiac catheterization may be effective and life-saving. This paper reports on 2 cases of Fontan failure due to volume overload and preserved ventricular function successfully treated by percutaneous approach.
