• Heart Catheterization Lab

  • Heart catheterization (heart cath) is a diagnostic procedure in which a catheter is inserted into the right or left chambers or vessels of the heart.


  • A heart catheterization  procedure allows the physician to investigate and locate heart disease. In some cases, a cardiologist will perform a minimally-invasive procedure known as a percutaneous coronary intervention (PCI) or angioplasty to open clogged arteries by using a balloon and/or stent.

    How the Test is Performed

    Prior to the test, the patient will receive a mild sedative. The patient's arm, neck or groin is cleansed and numbed before an intravenous (IV) line is inserted. The catheter is inserted through the IV and threaded to the heart. Once the catheter is in place, a cardiologist can:

    • Collect blood samples
    • Measure pressure and blood flow in the chambers and large arteries
    • Measure the oxygen levels
    • Examine the arteries using an X-ray technique, fluoroscopy, which provides real-time images
    • Perform a biopsy on the heart muscle
