Cardiac Catheterization Lababoratory, Cath Lab

Advanced Diagnostics and Interventions Available Around the Clock

The cardiac catheterization laboratory, or cardiac cath lab, at Froedtert & the Medical College of Wisconsin is staffed and ready 24 hours a day to diagnose and treat patients with acute coronary disease and heart attack. The lab has the most advanced digital imaging technology available and offers life-saving procedures like angioplasty and stent placement to open blocked arteries.

Cardiac catheterization offers a minimally invasive way to diagnose coronary artery disease (CAD), peripheral artery disease (PAD) and structural heart disease. It involves making a small incision in the groin to access an artery. A catheter (a thin, flexible tube) is place in the artery and moved up to the heart.

Diagnostic Catheterization

Diagnostic catheterization (angiography) is done to obtain information about the heart and its function. After guiding a catheter to the area being examined, a “dye” is injected through the catheter and X-ray images are taken to determine the presence of blockages in the arteries.

Catheterization to Unblock Arteries, Repair Heart Problems

Interventional catheterization is done as a treatment to open blocked coronary arteries or repair structural problems in the heart. Also known as endovascular procedures, these non-surgical treatments are performed from inside the blood vessel.

Procedures include:

Medical College of Wisconsin interventional cardiologists, and vascular and interventional radiologists are among the most experienced in the region performing diagnostic and interventional catheterization procedures.
