What Is Cardiac Catheterization?

Cardiac catheterization (cath) is a minimally-invasive procedure used to diagnose and treat some cardiovascular conditions. During the cath, the physician inserts a thin hollow tube, called a catheter, into an artery or vein in the patient’s groin, neck or arm. The catheter is then threaded through the blood vessels to the patient’s heart.

How Is Cardiac Catheterization Used?

In the Children’s Heart Institute cath labs, the cath team performs a wide range of diagnostic and therapeutic procedures, including:

  • Diagnostic procedures: measuring pressure and oxygen levels in the heart, obtaining biopsies and evaluating the structures of the heart.
  • Interventional procedures: examples include implanting valves in the heart, placing stents to open narrowed vessels, placing occlusive devices (to treat conditions such as atrial septal defects, ventricular septal defects and patent ductus arteriosus) and opening valves (balloon valvuloplasty) and vessels with angioplasty balloons.
  • Electrophysiology procedures, including testing for and treating irregular heartbeats (arrhythmias) and placing implantable cardioverter defibrillators (ICDs) and pacemakers.
