title: Collapse of the Advanta V12 Large Diameter covered stent following implantation for aortic coarctation.
abstract: We report a case of collapse of the Advanta V12 Large Diameter (LD) covered stent following previous successful implantation for native aortic coarctation. This unreported complication was successfully managed with subsequent stent redilation and implantation of two covered Cheatham-Platinum stents within the collapsed Advanta V12 stent. This case highlights the importance of correct stent apposition to the aortic wall and also raises some concerns regarding the radial strength of the Advanta V12 stent.
