tured due to instability of device. There was one instance of device embolization (2%) and none of erosion.
Conclusion: This is the second largest study of the CSO to date. These results indicate that the CSO is suitable for a wide range of inter-atrial communications, has excellent closure rates, is safe and is less expen- sive than alternative devices. Longer-term follow-up is required to evaluate risk of erosion.
literature revealed fourteen reported cases of effective transcatheter closure of ventriculopulmonary connections, 11 with an Amplatzer duct occluder, 3 Amplatzer septal occluders, and 1 Rushkind umbrella (one case required 2 devices). Twelve children were in good condition on follow up with clinical improvement, two had died non-procedure related deaths.
Conclusions: Residual ventriculopulmonary connections after a BCPC can be safely closed percutaneously using various devices. The multi- lobed, flexible quality of the Amplatzer Vascular Plug II makes it a par- ticularly suitable device for this procedure.

Background: Pulsatile antegrade flow in the pulmonary circulation in patients with a bidirectional cavopulmonary connection (BCPC) has been suggested to improve long term outcome, but may cause volume loading and prolonged pleural drainage, necessitating occlu- sion of the residual connection between the ventricle and the pul- monary artery.
Objectives and methods: To describe the utility of the Amplatzer Vas- cular Plug II in closing a residual ventriculopulmonary connection after BCPC and provide a review of the available literature on device closure of such connections in single ventricle patients.
Results: We used an Amplatzer Vascular Plug II (AVPII) for percutane- ous closure of the right ventricular outflow tract via retrograde ap- proach in an 18 month old child with double inlet left ventricle, nor- mally related great arteries, and pulmonary stenosis, presenting with prolonged chylothorax following pulsatile BCPC. The narrowest RVOT diameter was 5.5mm, occluded with a 10mm AVPII device with sta- ble result and successful decrease in pleural drainage. Review of the
