Cardiac Catheterization

---

Lake Granbury Medical Center's doctors use cardiac catheterization to both diagnose and treat heart disease. This minimally invasive, interventional cardiology technique uses a catheter (thin, flexible tube) that is inserted into the coronary arteries to examine the heart muscle, arteries, veins and heart valves with real-time x-ray style images (fluoroscopy). Cardiac catheterization procedures only require a tiny incision where the catheter is inserted into a blood vessel, so it can result in less blood loss, less pain and a quicker recovery for patients.

Diagnostic Angiography
A diagnostic angiogram is an outpatient cardiac catheterization procedure used to examine the inside of arteries and veins to detect blockages or narrowing of the blood vessels. Healthcare providers can use this to measure blood pressure, blood flow and oxygen levels, as well as evaluate the heart's pumping ability and the health of the valves. This catheter-based procedure is also used to collect biopsies and blood samples, and to evaluate other areas of the body, including:

• Peripheral angiography, or peripheral catheterization, enables doctors to locate areas of reduced blood flow in your lower body and legs. This procedure creates a map that shows where blood vessel blockages exist.
• Carotid angiography allows doctors to view the carotid arteries, which supply your brain with oxygen. It is used to detect narrowing or blockages that can lead to stroke.

Non-surgical Treatments for Heart Disease
Cardiac catheterization techniques are also used to treat heart disease by opening blocked arteries and blood vessels to improve blood flow. These advanced techniques offer a non-surgical alternative to treat many heart conditions on an outpatient basis. Lake Granbury Medical Center's board-certified interventional cardiologists use a variety of advanced catheter-assisted techniques, including:

• Angioplasty - A tiny balloon on the end of a catheter is inflated to push plaque against the wall of the artery to improve blood flow. A laser can also be used to break up the plaque.
• Stent placement - A stent, which is a small mesh tube, is placed in an artery to hold it open and improve blood flow.
