Heart & Vascular Tests and Procedures
HeartScore is a 10-minute CT scan of your heart that uses no needles and no fasting; you don't even have to run on a treadmill. Also known as coronary calcium scoring, this non-invasive test can find heart disease early, long before any symptoms appear. Recent research has shown a correlation between the amount of calcium in the coronary arteries and the likelihood of a future heart attack. If you smoke, or have diabetes, high cholesterol, high blood pressure, and/or a family history of coronary artery disease, you could be at risk.
Cardiac Stress Test: A cardiac stress test is performed by a physician or technician to determine the amount of stress that your heart can take before showing signs of damage such as an abnormal rhythm. The exercise stress test is also known as the exercise electrocardiogram, treadmill test, graded exercise test or stress ECG. It is used to provide information about how the heart responds to exertion. As you walk, your heart will be monitored for any changes or problems that would suggest your heart is not working optimally.
Nuclear Stress Test: Despite the action movie-title-sounding name, nuclear stress tests are very safe and ordinary. During this test, a small amount of radioactive tracer is injected into the patient. Physicians will use a special camera to identify the rays emitted from the radioactive tracer while it is in the body. By using this test, Baptist doctors can view clear pictures of the heart tissue on a monitor.
Regadenson (Lexiscan): For patients who are unable to perform the traditional exercise stress test, physicians will use a drug to mimic the heart's response to exercise. This is performed in conjunction with nuclear cardiac perfusion imaging.
Stress Echocardiogram: A stress echocardiogram provides a graphic outline of the heart's movement. This test can accurately visualize the pumping action of the heart when it's stressed. This test could reveal a lack of blood flow that can't always be seen from other stress tests.
Catheterization Procedures & Tests
Balloon Angioplasty: A specialist will inflate and deflate a balloon inside a blood vessel to compress plaque that could be blocking blood flow.
Coronary Stenting: A small metal coil or tube is placed in an artery to provide support to a weakened artery. Coronary stents are frequently used in conjunction with balloon angioplasty procedures. There are two types of stents: bare metal and drug-eluting.
Atherectomies: This catheterization technique removes plaque from arteries using several different advanced methods.
Pacemakers: These electronic devices are inserted with a catheter to regulate heart beats.
Ultrasound: By putting a small catheter in an artery, specialists can use ultrasound imaging to take pictures and better see blockages.
Valvuloplasty: Similar to a balloon angioplasty, in this procedure a larger balloon is inflated and deflated in order to expand a constricted valve.
Angiogram/Cardiac Catheterization: For this test, a specialist places a catheter in an artery in the wrist or groin, then guides the catheter to the area being studied. Contrast dye is injected into the catheter, providing detailed x-ray pictures of the heart and its blood vessels.
Electrophysiology Procedures & Tests
Electrophysiology (EP) focuses on the electrical system of your heart. Normally, electrical impulses cause your heart to beat at an appropriate rate and rhythm.
Electrical Studies And Ablations
EP studies and ablations are invasive procedures that require one or more sheaths to be inserted into your veins and possibly an artery. Some physicians insert a sheath in a blood vessel near the collarbone. Through these sheaths, catheters are placed that can send and receive electrical signals from your heart. X-ray is used to see these catheters during your procedure. X-ray dye may be needed to see your anatomy. If the physician is performing an ablation, he may choose radio frequency energy or cryoablation. After evaluating your medical history and test results, your doctor may recommend the insertion of a device.
If you heart can no longer provide the right electrical stimulus and conduct the current through the regions of your heart, your doctor may recommend a pacemaker. It will be inserted in the area under your left or right collar bone depending on your history. An incision and pocket for the device is made, and a lead or leads are inserted in a blood vessel and connected to the device. The pacemaker is placed in the pocket under the skin and the incision is then closed.
Internal Cardiac Defibrillators (ICD)
Some individuals are at high risk for life-threatening arrhythmias. This can be due to a physical condition, as well as hereditary conditions. An ICD can be inserted, which appears similar to a pacemaker, but is larger. As well as sensing and terminating fast heart rhythms from the bottom of the heart, defibrillators can also pace like a pacemaker. This provides protection from slow heart rhythms.
Biventricular Pacemakers And Defibrillators
If the left and right ventricles of the heart are not contracting at the same time, your heart may need help with this function and can be accomplished by adding a third lead through the coronary sinus. Your lead allows your device to improve the timing of your contractions.
Internal Loop Recorder
If tests do not provide the information your doctor needs to make a diagnosis for your symptoms, or if your doctor needs to have documentation of your heart rhythm for an extended period, a loop recorder implant may be suggested. This is a small device that is placed under the skin in the left chest through a puncture. This device can typically last three years, if needed, and then be removed.
This is a procedure used to get your heart in a regular rhythm with normal electrical conduction.
Tilt Table Test
Patients who are experiencing passing out or loss of consciousness may need this test. You will be asked to lie flat on a table connected to monitoring equipment. Safety straps are placed under your arms, around your waist, and above and below your ankles. Blood pressure, heart rate and oxygen saturations will be monitored and recorded. After a baseline of information is collected, your doctor will ask that the table be raised to an almost standing position, approximately 70 degrees.
