    THE AIM OF THIS RETROSPECTIVE STUDY WAS TO IDENTIFY THE PREDICTIVE FACTORS FOR RESIDUAL HT IN PATIENTS WHO HAD UNDERGONE COA STENTING. THIRTY CONSECUTIVE PATIENTS WHO HAD UNDERGONE COA STENTING BETWEEN 2007 AND 2015 WERE INCLUDED IN THE STUDY. ALL PROCEDURES WERE PERFORMED BY A SINGLE EXPERIENCED OPERATOR. THE TECHNICAL PARAMETERS WERE RECORDED DURING THE PROCEDURE. THE OPTIMAL OUTCOME OF THE PROCEDURE WAS DEFINED AS A RESIDUAL GRADIENT OF 10MM HG. THE LENGTH OF THE STENT WAS CHOSEN IN ORDER TO NORMALIZE THE PRESSURE GRADIENT BETWEEN THE ASCENDING AND DESCENDING AORTA CAUSED BY VARIOUS ANOMALIES RANGING FROM FOCAL NARROWING OF THE ISTHMIC AREA (DISTAL TO THE LEFT SUBCLAVIAN ARTERY), TO DIFFUSE AORTIC ARCH HYPOPLASIA. AS CHILDREN AND ADULTS WERE INCLUDED IN THE STUDY AN INDEXED STENT LENGTH, CORRESPONDING TO THE LENGTH OF THE STENT IN MILLIMETRES DIVIDED BY THE PATIENT'S HEIGHT IN METERS, WAS CALCULATED FOR USE IN THE STATISTICAL ANALYSIS THE INDICATION FOR STENTING WAS NATIVE COA OR RECOA . THREE PATIENTS UNDERWENT TWO CATHETERIZATION PROCEDURES TO ACHIEVE A SATISFACTORY HEMODYNAMIC OUTCOME (TRANSAORTIC GRADIENT 10MM HG). MEDIAN STENT LENGTH EMPLOYED WAS 29 MM. OF THE STENTS USED IN THE PROCEDURES, 19 PATIENTS WERE TREATED WITH AN INTRASTENT MAX LD. TWO SERIOUS COMPLICATIONS LINKED TO THE CATHETERIZATION PROCEDURE WERE OBSERVED: MIGRATION OF THE STENT AND CEREBELLAR STROKE. FOURTEEN OF THE PATIENTS (46.7%) HAD HT AFTER STENTING, THREE OF WHOM WERE CHILDREN.
