Study Start Date: October 2007
Estimated Study Completion Date: November 2012
Estimated Primary Completion Date: November 2011 (Final data collection date for primary outcome measure)

Experimental: Coarctation stenting Device: Stent enlargement of aortic coarctation
Transcatheter delivery of a metallic stent to enlarge region of aortic narrowing caused by the coarctation.
Other Name: Cheatham-Platinum Stent

Detailed Description:

The goals of this study are to provide information that will support labeling of both the CP bare metal and covered stents to treat native and recurrent aortic coarctation in selected children, adolescents and adults. The investigation will have two phases: Phase One will examine the safety and efficacy of the bare metal stent, and will collect information about the covered stent when used as rescue therapy for aortic injuries occurring during bare metal stent procedures.

The aims of the Phase One study are to assess the use of the CP bare metal stent to:

  1. provide a reduction equivalent to surgery in arm-leg systolic cuff blood pressure gradient 12 months after dilation and stent implantation, in comparison to the pre-dilation gradient;
  2. accomplish gradient relief with a shorter number of days in hospital than surgery;
  3. accomplish gradient relief with a rate of occurrence of serious procedure-related adverse events occurring within 30 days of dilation that is equivalent to surgery; and
  4. accomplish gradient relief with a rate of occurrence of post-procedural paradoxical hypertension that is lower than surgery.
