  • Title: Percutaneous recanalization and balloon angioplasty of congenital isolated local atresia of the aortic isthmus in adults.
    Author: Joseph G, Mandalay A, Rajendiran G.
    Journal: Catheter Cardiovasc Interv; 2001 Aug; 53(4):535-41. PubMed ID: 11515009.
    Abstract:
    Congenital isolated local atresia of the aortic isthmus is anatomically similar and morphogenetically related to congenital coarctation of the aorta and was encountered in 4 out of 26 consecutive adult patients selected for coarctation angioplasty at our center. Anterograde recanalization of the atresia was safely and successfully accomplished in all four patients, using a brachial approach. Balloon dilation in the four patients, with ancillary stent implantation in one patient, resulted in reduction of translesion gradient from 84 +/- 11 mm Hg to 9 +/- 7 mm Hg without complications. Angiography in the three non-stented patients after a mean follow-up of 13 months showed no evidence of restenosis, dissection or aneurysm formation, though one patient had mild dilatation of the posterior aspect of the aortic isthmus. The clinical presentation of patients with isolated local aortic atresia, and their short- to mid-term response to percutaneous treatment, is similar to that of patients with isolated severe coarctation of aorta.
