Cardiac Catheterization

---

Doctors at Northwest Healthcare 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 arteries to examine the heart, arteries and veins with real-time images (fluoroscopy). These procedures only require a tiny incision where the catheter is inserted into an artery, so it can result in less blood loss, less pain and a quicker recovery for patients.

In 2018, Oro Valley Hospital completed an upgrade to the cath lab, replacing the entire suite with more advanced technology. The new equipment is reliable and flexible, and produces high resolution images, giving physicians more detailed information to help make a diagnosis. In addition to traditional coronary angioplasty and stenting, in the new lab, physicians can also perform peripheral vascular procedures, allowing them to clear blocked arteries in the arms and legs.

Diagnostic Angiography

A diagnostic angiogram is an outpatient procedure used to examine the inside of arteries and veins to detect blockages or narrowing of the vessels. It can be used to measure blood pressure, blood flow and oxygen levels, as well as evaluate the heart's pumping ability and the health of the valves. Angiography is also used to collect biopsies and blood samples, and to evaluate other areas of the body.

Chronic Total Occlusion (CTO) (Northwest only)

Northwest Medical Center’s cardiac catheterization lab offers a procedure for CTO in which the arteries are narrowed or blocked, limiting blood flow. Many patients undergo open heart bypass surgery to restore blood flow. However, there is a CTO procedure available that may be another option for some patients instead of a bypass. Talk to your cardiologist about what’s best for you.
