Abstract
Interventional catheterization for congenital heart diseases, such as balloon dilation for stenotic valves or vessels, stenting, transcatheter closure of persistent arterial ducts and atrial septal defects, is now an indispensable treatment option. However, device lag in our country constitutes a serious obstacle for introduction of several devices, such as the radiofrequency guidewire, covered stent, percutaneous pulmonary valve, and so on, which will contribute to improved prognosis of patients with congenital heart diseases treated with less invasive procedures. In this review, I would like to introduce several novel devices that are expected to be approved in our country in the near future.
