Interventional Cardiology (Cardiac Catheterization)

World Leaders in Pediatric Interventional Cardiology

NewYork-Presbyterian has particular expertise in pediatric interventional cardiology, a unique specialty that involves the non-surgical treatment of congenital and acquired cardiovascular disorders for even the smallest hearts. In our state-of-the-art, dedicated congenital cardiac catheterization laboratories, our interventional cardiologists perform cardiac catheterization, a minimally invasive procedure in which a long, flexible catheter (tube) in inserted into a blood vessel and guided to the heart and surrounding blood vessels to examine the structures inside. From infants to young adults, patients of all ages benefit from a full range of diagnostic and therapeutic interventional cardiology procedures that require only a single day of hospitalization and eliminate the need for open-heart surgery.

Our interventional cardiologists are successfully performing some of the most technically demanding and innovative interventional cardiology procedures in children, including those used to treat congenital heart disease, pulmonary hypertension, and arrhythmias. Interventional cardiologists at NewYork-Presbyterian have developed several pediatric interventional cardiology procedures that have become the standard of care worldwide.

About Our Program

doctor with child patient

The Pediatric Interventional Cardiology program, operating across NewYork-Presbyterian Morgan Stanley Children’s Hospital and NewYork-Presbyterian Komansky Children's Hospital, is one of a few programs in the US with dedicated, state-of-the-art congenital cardiac catheterization laboratories and a cadre of interventional cardiologists with vast experience in all areas of pediatric transcatheter interventions.

Our interventional cardiologists use cardiac catheterization in children to diagnose and treat heart problems. These procedures are used to observe heart structure and function directly, measure blood pressure and oxygen levels at specific locations within the heart, treat arrhythmias, close holes in the heart, expand narrowed passages, open blocked heart valves or replace certain valves, and biopsy heart muscle. Children preparing for or who have had a heart or lung transplant may also undergo cardiac catheterization to examine the heart.

Our interventional cardiology team performs these procedures in a specialized suite equipped with the most advanced imaging modalities including 3D echocardiography, computed tomography (CT), MRI, and rotational 3D angiography.

Conditions we treat

Some of the conditions we treat using cardiac catheterization include:

  • Atrial septal defect (ASD)
  • Patent ductus arteriosus (PDA)
  • Ventricular septal defect
  • Aortic valve stenosis
  • Pulmonary valve stenosis
  • Mitral valve stenosis
  • Single ventricle heart defects
  • Coarctication of the aorta
  • Pulmonary artery stenosis

Our Approach to Care

Multidisciplinary and Collaborative Care

Our interventional cardiologists closely collaborate with pediatric cardiologists, pediatric cardiac surgeons, pediatric anesthesiologists, pediatric electrophysiologists, and pediatric cardiac nurses to provide your child with the safest, most advanced treatment available.

Pediatric Hybrid Heart Surgery

At the NewYork-Presbyterian Congenital Heart Center, each patient is evaluated for less invasive treatment options first. In some cases, a hybrid approach -- conventional surgery in conjunction with minimally invasive, catheter-based interventional approaches -- may enable the team to treat a condition with a single operation rather than a series of surgeries, or to treat conditions that would otherwise be inoperable. These less invasive alternatives use a much smaller incision through the breast bone or right chest, with the advantage of less pain, avoidance of cardiopulmonary bypass, faster return to normal activities and cosmetic advantages.

The Congenital Heart Center is one of a few US centers offering hybrid heart surgery to infants and children. These techniques are performed in a combined procedure with a cardiothoracic surgeon and an interventional cardiologist working side-by-side in the same operating room.

Seamless Care Throughout the Lifespan

With specialized training in pediatric cardiology, our interventional cardiologists understand the complex medical needs of people who were born with congenital heart defects, which often require follow up for life. Our interventional cardiologists form relationships with their pediatric patients and continue to perform procedures in patients after they have transitioned to adult cardiology care.

Thoughtful and Compassionate Care

We care for you promptly, thoroughly, and with the thoughtfulness and compassion that you and your child deserve. As a parent or caregiver, we consider you to be part of your child's team. We encourage you to ask any questions you may have and let us know how we can support you and your family during this experience

Treatments and Procedures We Offer

Our experienced interventional cardiologists perform a wide range of cardiac catheterization procedures in children, including:

  • Transcatheter valve implantation (pulmonary valve, tricuspid valve, and others)
  • Stent implantation and/or balloon angioplasty to open narrowed arteries and systemic and pulmonary veins, pulmonary arteries, aorta, and other vascular structures
  • Recanalization of completely occluded vessels or atretic valves through radiofrequency perforation
  • Device closure of atrial and ventricular septal defects, patent foramen ovale (PFO), and Fontan fenestrations
  • Balloon valvuloplasty of all cardiac valves (aortic, pulmonary, mitral, tricuspid)
  • Balloon dilation and/or stent implantation for treatment of coarctation of the aorta
  • Insertion of Impella Ventricular Support Systems for left and right ventricular dysfunction
  • Atrial septoplasty for patients with severe pulmonary hypertension and on extracorporeal membrane oxygenation (ECMO)
  • Balloon atrial septostomy to improve oxygen mixing within the heart
  • Percutaneous patent arterial duct closure
  • Hybrid therapies such as periventricular closure of muscular VSDs in small infants, hybrid palliation of hypoplastic left heart syndrome (HLHS), and intraoperative stent placement

Why Choose Us

Experts in Pediatric Interventional Cardiology Procedures 

Our interventional cardiologists are specially trained in pediatric interventional procedures, which they perform in patients of all ages — from newborns to adults — who were born with congenital heart disease. They perform more than 1,200 cardiac catheterizations each year, making our program the largest pediatric interventional cardiology program in the tri-state area and one of the busiest in the country.  We routinely provide second opinions and treat complex patients who have not found successful treatment elsewhere.

National Leaders in Pediatric Hybrid Heart Surgery 

NewYork-Presbyterian’s Congenital Heart Center is one of just a few U.S. centers to offer hybrid heart surgery to infants and children. Hybrid heart procedures combine conventional surgical methods with cardiac catheterization. These less invasive alternatives use a smaller incision through the breast bone or right chest, with the advantage of less pain, no need for a heart-lung machine, a faster return to normal activities, and a better cosmetic outcome.

Pioneers of Innovative Interventional Cardiology

Interventional cardiologists at NewYork-Presbyterian developed many of the pediatric interventional cardiology procedures that have become the standard of care worldwide. Our team frequently participates in research projects and multicenter clinical trials to remain at the forefront of innovations and the development of less-invasive, catheter-based therapies for people with congenital heart disease. Our team looks forward to the continuous evaluation of novel interventional cardiology approaches to enhance the lives of this complex group of patients.

Transcatheter Pulmonary Valve Replacement

In 2007, interventional cardiologists at NewYork-Presbyterian Morgan Stanley Children’s Hospital performed the first transcatheter pulmonary valve replacement in New York. Until that time, replacing a faulty pulmonary valve could only be done with open-heart surgery. Today, transcatheter pulmonary valve replacement has evolved into a viable alternative to surgical valve replacement, allowing the patient’s pulmonary valve to be replaced non-surgically and decreasing the number of open-heart surgeries a growing child may need over a lifetime.

  • NewYork-Presbyterian is the primary referral center for transcatheter pulmonary valve replacement in the greater New York City area.
  • Over the last decade, our interventional cardiologists have performed over 200 transcatheter valve replacement procedures in children and adults with congenital heart disease.

Percutaneous Patent Ductus Arteriosus Closure

After birth, the ductus arteriosus normally closes within two or three days. However, in premature infants, the opening often takes longer to close. If the connection remains open, it's referred to as a patent ductus arteriosus (PDA), an abnormal opening that causes too much blood to flow to the baby's lungs and heart.

  • With expertise in PDA closure in infants, interventional cardiologists at NewYork-Presbyterian Komansky Children’s Hospital were the first in Manhattan to perform catheter-based PDA closures in preterm infants weighing less than 1.5 kg. Currently this procedure is performed at NewYork-Presbyterian Morgan Stanley Children’s Hospital and NewYork-Presbyterian Komansky Children’s Hospital.
