Background: Balloon valvuloplasty and surgical aortic valvotomy have been the treatment mainstays for congenital aortic stenosis in children. Choice of intervention often differs depending upon centre bias with limited relevant, comparative literature.
Objectives: This study aims to provide an unbiased, contemporary matched comparison of these balloon and surgical approaches.
Background: In patients with patent ductus arteriosus (PDA), transcatheter closure is the current procedure of choice. There are multiple devices available with limited current comparative data and varied recommendations for device selection.
Objective: To assess the efficacy and safety of the Flipper coil (FC) and the Amplatzer Duct Occluder (ADO).
