Figure 2. Panels A and B. Initial right ventricle angiogram demonstrating RVOT and pulmonary valve narrowing in both (Panel A) fron- tal and (Panel B) lateral planes. Panel C. 5-F short sheath paced through a small subxiphoid incision. Panel D. Right ventricle angiogram following stenting of the RVOT with a 5 × 16-mm stent.
Ultimately, these cases re ect a learning curve with RVOT stenting in infants weighing < 2 kg. Although an uncomplicated outcome is possible with a stan- dard transcutaneous approach, the margins of error are small, and complications are poorly tolerated. We believe a hybrid approach through a small subx- iphoid incision provides the most direct route to the
RVOT in small infants and reduces hemodynamic in- stability, which may allow time to assess stent posi- tion adequately.
In conclusion, this case series highlights the evo- lution of an approach to RVOT stenting in infants weighing < 2 kg. Although a successful outcome with a transcutaneous approach is possible, complications
