Diagnostic Procedures

  • Radial catheterization — When performing a catheterization, physicians have the option to use the radial approach (entering through the wrist) or the more traditional femoral approach (entering through the leg/groin). The Heart & Vascular Institute at St. Anthony’s is a leader in performing radial catheterization. This technique has several advantages, including eliminating the risk of internal bleeding. Patients are more comfortable because they can sit up, walk and eat immediately after the procedure, compared to patients of femoral catheterization who must remain immobile for several hours. Radial catheterization also gives patients the opportunity to go home the same day.
  • 3D heart mapping — Software allows our physicians to build a 3-D model of each patient’s heart. They then use that model while treating the patient, instead of basing the care on an x-ray picture or a theoretical model of the heart. This increases the accuracy with which the physician can treat the patient, while also decreasing the use of x-rays.
  • Cardiac magnetic resonance imaging (MRI) – This scan uses radio waves, magnets, and a computer to create pictures of your heart to examine its structure and function.
  • Diagnostic catheterization – For this diagnostic procedure, small tubes called catheters are inserted into veins and/or arteries and moved into the heart to measure blood pressure in various chambers, to take blood samples and/or to place dye to allow visualization during an x-ray.
  • Nuclear stress test —This test is performed by administering medicine to test the effect of exercise on the heart.
  • Treadmill stress test—This test is performed using a treadmill to test the effect of exercise on the heart.
  • Electrocardiogram (EKG or ECG) — A diagnostic procedure that measures electrical activity in the heart, including the rate and regularity of heartbeats.
  • Echocardiogram (Echo) — An ultrasound of the heart, this diagnostic procedure allows physicians to view the chambers and valves of the heart and measure the speed and direction of blood flow.
  • Transesophageal echocardiogram (TEE) — During this diagnostic procedure, the patient swallows a probe that stops at heart level. Through ultrasound technology, it offers a clear view of the heart’s function.
  • Holter monitor — The patient wears a portable device for 24 hours that continuously records heart rate and rhythm during normal daily activities.
  • Event monitor —The patient wears a portable recording device for up to 30 days; turning it on for brief periods of time to record heart rate and rhythm as instructed by his or her physician or technician.
  • Venous ultrasound – An ultrasound of the veins which shows how well blood is flowing.
  • Advanced mapping for liver disease – This is a scan that allows physicians to identify an area to target for treatment
  • Same day liver biopsy – This diagnostic procedure uses a needle to collect a sample of the liver tissue with results available the same day.

Heart & Vascular Facilities

  • Cardiac catheterization lab — Procedures such as heart catheterization, angioplasty, stenting, atherectomy,  atrial septic defect (ASD) closure, and  patent foramen ovale (PFO) closure are performed in this highly advanced setting to repair certain heart conditions or open narrowed or blocked arteries and blood vessels.
  • Electrophysiology lab — Procedures are performed here to assess the characteristics of irregular heart rate, as well as treat chronic irregular heartbeat. As an example, pacemakers may be implanted to help regulate a heartbeat that is too slow or cardiac defibrillators may be inserted to help regulate too rapid of a heartbeat.
  • Surgery — Our board-certified cardiovascular and cardiothoracic surgeons use traditional open and minimally invasive (beating heart) surgical techniques to perform a full range of heart surgeries, including coronary artery bypass graft; valve repair and replacement; and other surgical procedures on the heart muscle, valves, arteries and other structures.
