Figure 3: Static atrial septoplasty with 4 mm (a), 7 mm (b), and 10 mm (c) balloons deployed over the radiofrequency wire. Control hand injection performed in the left atrium (d) demonstrates a hypoplastic left ventricle, left atrial appendage, and flow of contrast across the newly created atrial septal defect to the right atrium
