Interventional Cardiology

Interventional Cardiology

Interventional cardiology is an internationally recognized program that provides a full spectrum of diagnostic and interventional cardiac catheterization procedures. We offer state-of-the-art technology including two custom-built Hybrid Cardiac Catheterization Suites and a Hybrid Operating Suite equipped to provide for the interventional treatment of all patients (from a 700g premature infant to an 80-year-old adult) with congenital and acquired heart disease. This includes interventional transcatheter therapy of adults with congenital or structural heart disease.

US News Badge Cardiology

Nationwide Children's Hospital is ranked by U.S. News & World Report for Cardiology and Heart Surgery.

About our Interventional Cardiology Program 

We believe quality and safety are top priorities. Our program participates in national and international quality improvement efforts including:

  • Congenital Cardiac Catheterization Outcomes Project (C3PO) Registry
  • Improving Pediatric and Adult Congenital Treatment (IMPACT) working group of the Adult Congenital and Pediatric Cardiology (ACPC) Section Member

Interventional cardiology is truly the future of heart care for children and adults, allowing complex procedures to be successfully completed while leaving the patient with a band-aid, rather than a scar. At Nationwide Children's, the full range of interventional cardiology procedures is available:

  • Balloon dilation of stenotic valves or narrowed vessels
  • Catheterization
  • Coil embolization of undesirable vessels and patent ductus
  • Radiofrequency and Cryogenic catheter ablation of accessory conduction pathways
  • Stenting of narrowed vessels

Meet Our Team 

Dramatic improvements in interventional cardiac catheterization treatments and techniques allow specialists to care for more and more cardiac problems without surgery. Our cardiac interventionists are among the best in the world, pioneering treatments right here at Nationwide Children's. This innovative spirit has led to a collaborative interventional catheterization and cardiothoracic surgery program, causing the lines between transcatheter and surgical treatment strategies to blur. Thus, The Heart Center’s need for a therapeutic suite that is compatible with both interventional cardiology and cardiothoracic surgery.

Cardiac Cath Suite

Cardiac Cath Suites

The Heart Center has taken a cutting-edge leap with the opening of two hybrid cardiac suites, which combine innovations in catheterization, diagnostic and telecommunication technologies.

Hybrid Operating Suite

Hybrid Congenital Cardiac Operating Suite

Unlike catheratization suites, the Hybrid Operating Suite is designed specifically around the cardiac surgeon and cardiac surgical patient, offering new advanced access and imaging in the operating room.

Meet Zoey

Just two years old at the time, Zoey Jones was told she would need a heart and lung transplant for her failing organs, a complication due to the single ventricle heart defect she was born with. She was referred to Nationwide Children’s Hospital where they began to prepare for a transplant, when a second look in the catheterization laboratory (cath lab) led doctors to believe her heart and lungs were strong enough to avoid transplant altogether.

Nationwide Children's Stent Development Lays Groundwork for Melody Valve

The Heart Center had a key role in the FDA approval of the Medtronic Melody Transcatheter Pulmonary Valve and Ensemble Delivery System as well as with the development of both the stent and balloon-in-balloon products. This new treatment is the first in the United States offering minimally-invasive treatment options for congenital heart disease patients. This will help minimize and delay the need for multiple open heart surgeries over a patient's lifetime. Nationwide Children's was one of five initial clinical trial locations.
