Patent ductus arteriosus (PDA) transcatheter closure is a widespread procedure. However in some cases PDA measurements may be unclear and choice of the proper device could be quite difficult. This may happen in large PDA and in particular in adults. We have developed a new technique using an ASD sizing balloon to measure the PDA in order to better understand PDA anatomy and size. The first step is to create an artero-venous circuit across the PDA. A 24 or a 34 mm Amplatzer balloon sizing for ASD closure is placed over the wire from the venous access in the descending aorta. Then, the balloon is inflated and gently pulled back across the PDA toward the pulmonary artery. The frame where the balloon is exactly across the PDA is chosen and measurements performed. In conclusion, a new method for PDA measurement in large PDA is reported. The procedure is safe and reliable. © 2015 Wiley Periodicals, Inc.
