Does percutaneous transluminal angioplasty reduce the systolic pressure gradient in patients with coarctation restenosis?
Does percutaneous transluminal angioplasty reduce the systolic pressure gradient in patients with coarctation restenosis?
Percutaneous transluminal angioplasty effectively and persistently reduces the systolic pressure gradient in pediatric and adolescent patients with coarctation restenosis.

Acute gradient reduction with PTA in coarctation restenosis supports procedural feasibility; leaves open durability and outcomes in larger cohorts.
Percutaneous transluminal angioplasty (PTA) was used successfully to treat coarctation restenosis in seven patients. The patients were 10 months to 17 years old at the time of the angioplasty, and the initial coarctation repair had been performed 10 months to 16 1/2 years previously. PTA reduced the systolic pressure gradient across the coarctation from a mean of 58 mm Hg before the procedure to a mean of 13 mm Hg immediately after PTA. Follow-up has been from 1 to 14 months and indicates that the decrease in the systolic pressure gradient is persistent.
