Abstract:
We report a case of a 14-month-old child with ascending aortic obstruction (AAO) post cardiac transplantation, who underwent successful percutaneous ascending aortic stent angioplasty. Congenital or acquired AAO is typically treated with surgical augmentation. The experience with percutaneous techniques is limited and often avoided due to challenges with equipment stability and proximity to coronary arteries and aortic valve leaflets. This case highlights that a percutaneous approach to relief of AAO is a feasible alternative even in small children utilizing a newer pre-mounted stent.
