Interventional cardiac catheterization

Cardiac catheterization is a specialized procedure for diagnosing and treating heart conditions. Our cardiologists can insert a long tube – or catheter – into a vein or artery, allowing access to the heart. We often use this minimally-invasive procedure to treat congenital heart defects in infants and children instead of open-heart surgery.

Our philosophy is to avoid surgery whenever possible. In many cases, we can also combine diagnostic and interventional catheterizations, which minimizes the number of procedures your child might undergo.

Catheterization services

Our full-service cardiac catheterization capabilities include a biplane lab – a cutting-edge technology that minimizes radiation exposure – dedicated to diagnostic evaluation and therapy in children. 

Our interventional cardiac team has expertise in:

  • Balloon valvuloplasty for aortic valve or pulmonary valve and mitral valve stenoses
  • Closure of PDA and anomalous blood vessels
  • Creation of atrial septal defects when clinically needed (e.g. pulmonary hypertension)
  • Hypoplastic left heart syndrome (HLHS)
    • Management of intact atrial septum 
    • Hybrid palliation
  • Intracardiac echocardiography (ICE)
  • Radiofrequency perforation for pulmonary atresia
  • Septal defect device closure of most atrial and some ventricular septal defects (ASDs, VSDs, PFOs)
  • Stent Implantation for:
    • Branch pulmonary artery stenosis
    • Aortic coarctation
    • Stenotic conduits and homografts 
    • Baffle obstruction in Mustard and Senning for patients with transposition of the great arteries (TGA)
  • Superior vena cava reconstruction for SVC syndrome or thrombosis
