Figure 1 A caudally angled antero-posterior projection best profiles the region of coarctation in patients after Norwood. Note that the narrowest region of the arch is approximately 4 mm in diameter, compared with the diameter of the lumen of the descending aorta at the level of diaphragm, measuring 11 mm.

Figure 3 Kaplan-Meier curves depicting survival beginning six months after Norwood. Patients who developed re-coarctation treated by balloon angioplasty (BA) are displayed by the solid line, those who never developed re-coarctation by the dashed line. Statistical comparison performed using the log-rank test demonstrated no difference in survival rates between the two groups (p < 0.05).
