Cardiac catheterization
This procedure allows the cardiologist to see the coronary vessels that supply the heart muscle with oxygenated blood. If your doctor discovers a significant blockage, he or she may decide to treat you:
1. With medications
2. Send you for open-heart surgery to bypass the blockage
3. Perform a coronary interventional procedure, such as angioplasty or stent
 
Angioplasty
Angioplasty is one treatment for blocked vessels. This procedure can be done right in the Cardiac Catheterization Lab. A balloon is inflated at the blockage to open the vessel, restoring blood flow to the heart.
 
Stents
Stents are another treatment for blocked vessels that can be performed right in the Cardiac Catheterization Lab. They are small metal tubes the cardiologist inserts into the coronary artery at the site of a blockage to restore blood flow to the heart. New, drug-eluting stents minimize scar tissue at the site, which reduces the need for repeat procedures. 
 
Peripheral vascular procedures
These procedures allow your cardiologist or vascular surgeon to obtain images of blockages, but in arteries in the kidneys, pelvic area, legs, neck and arms as well as peripheral arteries. If a blockage is found, the blockage can be treated right in the Cardiac Catheterization Lab.
 
Electrophysiology studies
St. Mary's of Michigan offers a special lab for these procedures, which are used to diagnose and treat irregular heart rhythms. We offer basic EP studies, tilt table studies, pacemakers, ablations, and laser lead extractions.
 
 
 
Non-invasive procedures
St. Mary's of Michigan has a comprehensive non-invasive cardiology department for tests needed to accurately determine the level of heart care you need:
• Four echocardiography labs for echocardiograms, transesophageal echocardiograms (TEEs) and stress echo procedures
• EKGs, Holter monitors, and event monitors
• Exercise stress tests, dobutamine stress tests, stress echo procedures, and nuclear cardiac imaging
