Characteristics of Pediatric Cardiology

The Pediatric Cardiology Unit provides cardiac catheter intervention for children with congenital heart disease. Cardiac catheter interventions allow non-surgical correction, including atrial septal defect closure, patent ductus arteriosus closure, valvuloplasty, angioplasty, stent implantation, and embolization procedures. Our team is recognized as one of the top-ranked pediatric catheterization units in Japan.

Transcatheter ASD closure

Most secundum type atrial septal defects (ASD) are amenable to transcatheter closure. The Amplatzer Septal Occluder and the Occlutech Figulla Flex II are used for transcatheter closure.

Transcatheter PDA closure

Most patent ductus arteriosus is suitable for transcatheter closure. The Amplatzer Duct Occluder and the coil are used for transcatheter closure.

Balloon valvuloplasty for pulmonary valve

Transcatheter balloon valvuloplasty for pulmonary valve is one of the first catheter interventions developed for children. Many children have benefited from less invasive treatment.

Balloon angioplasty / stent implantation

Transcatheter balloon angioplasty and stent implantation for stenotic lesions are less invasive than open surgery.


Embolization is a minimally invasive procedure that involves insertion of a device or a coil into a blood vessel in order to close it.
