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

Our cardiac cath lab team is able to treat all areas of cardiac diseases, such as heart arrhythmias, coronary artery diseases and pericarditis. Additionally, our innovative nonsurgical lab means our patients often recover with less pain, experience fewer side effects and can go home sooner.

Cardiac cath lab information

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.

Check in

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.
