Cath Lab at SSM Health St. Mary's Hospital - St. Louis

The Cath Lab, located on the ground level at SSM Health St. Mary’s Hospital, provides cardiac catheterization to see how well your heart and coronary arteries are working and to look for any abnormalities or blockages. When you need critical care like cardiac catheterization, you want to know you’re in good hands. Patients are encouraged to park in the west parking garage off Bellevue Avenue, come in the west entrance and visit the outpatient registration office there before navigating to the Cath Lab on the same floor.
