Is the Coast Clear for Stent Angioplasty of Coarctation?
Coarctation and re-coarctation of aorta have been treated successfully with endovascular therapy including balloon angioplasty or stent angioplasty for over three decades.1,2,3,4 After successful surgical repair reported by Craafoord,5 the concept of angioplasty in the coronary arteries by Gruntzig6, opened up a new strategy of treatment of native and recoarctation.
Balloon angioplasty was successful in relieving the obstruction but the long term results were disappointing with the recurrence of obstruction and incidence of aneurysm formation in the earlier studies7,8. This was soon abandoned in infants and young children to make way for improved acute and intermediate outcomes from surgery that included techniques such as end-to-end anastomosis, extended end to end anastomosis, subclavian flap repair, patch angioplasty and interposition grafts for complex coarctation9.
