Cardiac catheterization

Cardiac catheterization is a procedure used to diagnose and treat heart conditions. This nonsurgical method can be used to determine if you have heart disease, check your heart muscle function or expand narrowed arteries to improve blood flow to the heart.

Heart cath lab services we offer

Heart catheterization procedures access your heart and blood vessels using thin tubes, known as catheters, as opposed to traditional surgery. By using minimally invasive catheters, our interventional cardiologists can detect and treat cardiovascular diseases, while prioritizing your overall health and helping you experience less pain and a faster recovery.

Diagnostic cardiac catheterization procedures

Some of the diagnostic procedures we offer include:

  • 3D mapping
  • Coronary angiography
  • Heart biopsy
  • Intravascular ultrasound
  • Nitric oxide study for pulmonary hypertension
  • Peripheral catheterization
  • Pressure wire
  • Renal percutaneous transluminal coronary angioplasty (PTCA) stent
  • Transesophageal echocardiogram (TEE)

Interventional cardiac catheterization procedures

Cardiac catheterization is also an effective interventional method. It is used to treat both acute and chronic cardiac conditions, such as arrhythmias and coronary artery disease. As part of our nationally-recognized Cardiac Alert programs, we offer interventional heart procedures that include:

  • Alcohol ablation
  • Atrial fibrillation (AFib) treatment
  • Atrial flutter treatment
  • Atrial septal defect (ASD) repair/closure
  • Biventricular pacemakers
  • Cardioversions
  • Convergent procedure
  • Drug-eluting stents
  • Electrophysiology (EP) ablation
  • High-risk coronary stenting with advanced therapies
  • Implantable defibrillator placement
  • Left atrial appendage closure (LAAC) device insertion
  • Patent foramen ovale (PFO) repair/closure
  • Pericardiocentesis
  • Percutaneous transluminal coronary angioplasty (PTCA)/stents
  • Renal percutaneous transluminal coronary angioplasty (PTCA) stent
  • Rotational atherectomy (RA)
  • Supraventricular tachycardia (SVT) ablation
  • Tilt table tests
  • Valvuloplasty
  • Vascular surgery
  • Ventricular tachycardia treatment

Our cath lab teams

The teams of expert clinicians at our cath labs are experienced and highly trained to diagnose and treat cardiac conditions. Alongside our physicians are:

  • Board-certified cardiac nurse practitioners
  • Board-certified EP technologists (a rare designation with only 600 worldwide)
  • Cardiovascular nurse navigators to help with care after cardiac procedures
  • Nurses with advanced certification in cardiac and critical care nursing

What to know for your procedure

Our cath labs offer cardiac catheterizations and EP procedures on an outpatient basis. Your cardiologist will schedule your procedure ahead of time.


Prior to your test day, please contact your insurance provider to determine the amount of copay required for the procedure. Your copay is due at the time of service.


Please arrive two and a half hours prior to the start of your test and check in at the admissions desk in the main lobby on the first floor. Please be sure to bring your driver’s license, insurance card(s) and copay to admissions.

Procedure details

The length of your procedure will vary depending on what your cardiologist has ordered. Most procedures take approximately two hours for preparation, two hours for the procedure and four hours for recovery. If a coronary stent or balloon is required during your procedure, you may need to stay overnight.

Ablation procedures can take four to five hours and require an overnight stay.

Getting home after your procedure

All cath lab patients must have someone to drive them home. You may not drive yourself after a cath lab procedure. Please make arrangements ahead of time to have someone take you home.
