Abstract
IntroductionUse of balloon expandable intravascular stents for treatment of coarctation of the aorta is well established. There are limited data for stenting the transverse aorta (TAO). This study aims to evaluate immediate and midterm results of TAO stenting in a multi-center cohort.MethodsRetrospective multicenter study of patients who underwent clinically indicated catheter intervention for aortic obstruction from June 2009 - December 2017. TAO stenting was defined as stent placement proximal to the third head and neck vessel. Demographics, procedural details, complications and medications were assessed immediately post procedure, at 6 month and most recent follow up.ResultsFifty subjects, 12 (24%) native and 38 (76%) repaired aortic arches, from 7 centers were included. Demographics, procedural and follow-up details are in Table 1. Aortic diameter increased from 5.7±4.65 to 10.1±5.93 mm (p<0.001) and gradient decreased from 22±11 to 3±4 mmHg (p<0.001) acutely. Two patients had stent repositioning following embolization during deployment. There were no major acute or late complications (mean 3.2±2.1 years). Four subjects died during follow up, all unrelated to the procedure. There was 1 unplanned and 7 planned reinterventions (5 catheterizations, 2 operations), with operations for subjects <1 month old where initial stenting was performed to allow improvement in ventricular function. Despite an overall improvement in hypertension, antihypertensive medication was continued in 16/36 (45%) of subjects.ConclusionsCoarctation of the aorta involving the TAO is effectively and safely treated with stenting in select patients. While there is improvement in systemic hypertension after TAO stenting, almost 50% of patients had persistent hypertension independent of residual stenosis.
