Prediction of Stenting Success
Presently other than baseline aortic diameter there is no predictor of aortic stenting efficacy. Likely factors determining outcome that have not been evaluated are aortic distensibility abnormalities because of intrinsic coarctation wall abnormalities and scar burden from previous surgical repairs in re-coarctation. There are no non-invasive means to determine these aortic wall properties to make stenting efficacy predictions. A long-term validation effort will be to assess the ability of pre-intervention MRI measures of aortic flow, wall distensibility and scar burden to predict stenting acute and medium term (1 year) hemodynamic efficacy.
