Terumo 5 Fr radial sheath (the manufacturer recommends a 4 Fr sheath, but in our experience the balloon, when deflated after intervention, needs a 5 Fr sheath for extraction) with access from the right femoral vein (Figure 2).
Patient (32 weeks of gestation, 1.2 kg) with TGA, VSD, and restrictive ASD. Edwards Fogarty Fortis Catheter with straight tip.

The catheter is of a single-lumen design with a stylet inside, but without an end-hole (Figures 3 and 4). The stylet allows for manual modification of the tip shape of the catheter (Figure 5).
Individually modified catheter tip according to the atrial anatomy of the patient (arrow).

After the removal of the stylet and balloon inflation with 0.75 cc of saline (Figure 6), BAS was performed without any complication. ASD seemed to be too small again (Figure 7), and a second and third BAS were performed by inflating 1 and 1.5 cc of saline into the balloon, respectively (Figures 6 and 8). After that, a 5 mm wide ASD was seen on echocardiography, and the intervention was stopped (Figure 9).
