Austin Heart provides comprehensive diagnostic services, usually located within the physician office or in a conveniently located St. David’s Imaging Center.
Many procedures used to diagnose heart and vascular disease utilize some form of imaging. Austin Heart's echo, vascular and nuclear imaging departments have each received national accreditation from the Intersocietal Accreditation Commission. Less than 5% of cardiology practices, and only three practices in Texas, have been awarded all three accreditations.
Diagnostic Services Provided:
- Echocardiography An echocardiogram is a test that uses ultrasound to create images of the heart. An ultrasound sends sound waves through the area of the body being studied to create images of internal body structures. The test is also known as an "echo."
- Positron Emission Tomography (PET) PET is a type of nuclear medicine imaging. The test is performed to allow cardiologists to evaluate the structure and function of the heart. PET uses a small amount of radioactive material called Rubidium to help produce three-dimensional images of the heart. PET delivers high quality images with high diagnostic accuracy.
- Peripheral Artery Imaging - Carotid, Abdominal, Renal Artery and Lower Extremity Ultrasound Peripheral arterial imaging is a test that provides your doctor with information about the condition of the arteries and veins outside of your heart using ultrasound to develop a 2 dimensional image and to evaluate the flow of blood through that vessel.
- Lower Extremity Peripheral Arterial Testing and Ankle-Brachial Index Lower Extremity Peripheral Arterial testing provides your doctor with information about the condition of the arteries in your legs. Testing is performed when your doctor suspects that your symptoms might be caused by plaque (fatty buildup) in these arteries known as Peripheral Artery Disease (PAD).
- Myocardial Perfusion Test / Nuclear Stress Test A Myocardial Perfusion Scan (also called a nuclear stress test) allows your doctor to see how your heart muscle works both when you are resting and when your heart is stressed. Your heart can be “stressed” with exercise on a treadmill or with drugs that increase the heart rate or change the way blood flows through the coronary arteries.
- Vascular Advantage Vascular Advantage is a three-part screening offered at Austin Heart to help assess your risk for stroke, an abdominal aortic aneurysm (AAA), and peripheral vascular disease (PAD). These affordable preventative screenings are convenient, non-invasive, and painless.
- Transesophageal Echocardiogram A transesophageal echocardiogram (TEE) is a test that uses ultrasound waves to look at your heart from inside your chest. For this test, a small, flexible tube (or probe) with an ultrasound transducer at its tip is carefully placed in the esophagus to view the structures of the heart in a more comprehensive manner than a traditional transthoracic (through the chest wall) approach can provide. As this test is more invasive, patients are usually given medication to relax and sleep during the procedure.
- Tilt Table Testing During a tilt table test you lie on a special table that is progressively tilted towards the head-up position while your blood pressure and heart rate are monitored. Tilt table testing is done to reproduce the type of situation that may cause you to faint in order to determine if your fainting episodes are related to your cardiovascular system.
- Exercise Stress Test This is a test that uses an electrocardiogram (ECG or EKG) to record your heart’s electrical activity while walking on a treadmill. The test is performed to help evaluate chest pain and how your heart is functioning.
- Stress Echocardiogram This is a test that allows your doctor to compare images of your heart muscle at rest with how it functions when stressed during exercise. Your heart rate is increased through exercise on a treadmill. In some cases, a drug is used to increase the heart rate rather than exercise. An echocardiogram is performed before you begin exercising and then immediately after you stop. Your heartbeat and blood pressure are also monitored during your stress echocardiogram.
- Holter Recording A Holter recorder is a device that continuously records the electrical activity of your heart for 24 hours. The recorder records your heartbeat while you perform your usual daily activities. You wear the recorder and keep a diary to report symptoms or events to help your cardiologist determine if your symptoms are related to an abnormality of your heart rhythm.
- Event Monitor An Event Monitor is a small recording device that looks similar to a pager. You are given a recorder to use for 30 days and you push a button to record your heart activity any time you experience symptoms. The recorder records your heart activity for about 2 minutes and helps your cardiologist determine whether your symptoms are related to an abnormal heart rhythm.
- ECG or EKG An electrocardiogram demonstrates how your heart's electrical system is working. The ECG senses and records the flow of electrical current through the muscle cells in your heart. The results are printed on a strip of paper or recorded electronically.
- Coronary CT Angiography Coronary CT Angiography (or CTA) is a diagnostic test that uses specialized x-ray beams to reconstruct and evaluate the structure and function of the heart, the coronary arteries, and the great vessels that lead to and from the heart.
- HeartSaver CTHeartSaver CT, which does not require a physician’s order, is an Ultrafast CT that provides sharp, clear images of the heart. These images can determine if there is abnormal calcium buildup in the coronary arteries which can indicate increased risk for heart attack. Early detection of heart disease is critical to prevent a heart attack before it occurs.
