Cardiac diagnostics and treatment programs

Cardiac catheterization

Memorial Hospital Jacksonville is the leading provider of heart catheterizations in northeast Florida. Cardiac catheterization is a procedure used to:

  • Locate blockages in the blood vessels
  • Determine the amount of oxygen in the heart
  • Test pressure
  • Perform a tissue biopsy in the heart
  • Diagnose heart defects
  • Look for problem with heart valves

Recovery time from a cardiac catheterization procedure is quick and there is a relatively low risk for complications. Cardiac catheterizations are generally performed under local anesthesia, meaning you are awake for the procedure, as it causes little or no pain. A dye is injected into a small tube so the cardiologist can get a clear view of the affected area.

 Cardiac catheterization is also used in the following procedures that treat heart disease:

  • Angioplasty, with or without a stent placement
  • Ablation for heart arrhythmia
  • Thrombectomy for blood clots
  • Closure of holes in the heart, including PFO (patent foramen ovale)
  • Repair or replace leaky heart valves

PET/CT scan

PET and CT scans are both state-of-the-art imaging tools that allow physicians to detect heart disease early. While these scans are useful on their own, when they are combined they provide radiologists and doctors with information regarding both structures and functions of cells. PET and CT scans provide images of blood flow to the heart, allowing cardiologists to detect blockages within the arteries. The scans are non-invasive and painless, and results are known quickly.

This procedure determines early signs of heart disease and helps your physician manage and plan treatment options.

Electrocardiogram (EKG)

Your physician may request that you have an electrocardiogram (EKG or ECG) test. An EKG or ECG is a test that checks for problems with the heart’s electrical activity. This test is performed to:

  • Determine the cause of unexplained chest pain, such as heart attack, inflammation of the sac surrounding the heart (pericarditis) or reduced blood flow to the heart muscle (ischemia)
  • Determine the cause of certain heart disease symptoms, such as unexplained chest pain, shortness of breath, dizziness, fainting or rapid/irregular heartbeats
  • Check the heart’s electrical activity
  • Check the heart chamber wall thickness
  • See if medicines are working and if they are causing certain side effects
  • Check how well pacemakers or implantable cardioverter-defibrillators (ICDs) are working to control a normal heartbeat
  • Check the health of the heart when other diseases or conditions are present, such as high blood pressure, high cholesterol, cigarette smoking, diabetes or a family history of early heart disease

An echocardiogram, also called an echo, is an ultrasound of the heart. It uses standard ultrasound techniques to give your doctor images of your heart that can be used to:

  • Assess cardiac valve areas and their function
  • Assess any abnormal communications between the left and right side of the heart
  • Asses any leaking of blood through the valves, known as valve regurgitation
  • Assess the ejection fraction
  • Assess cardiac measurements

Cardiac ablation

Cardiac ablation is used to fix heart rhythm problems. Electrodes are placed in the heart to measure the electrical activity in specific areas of the heart. If a problem area is found, an electrical wave will be sent to the area to fix the problem.

Pacemaker / ICD

A pacemaker is a device that is implanted into the body, generally in the chest or abdomen, which is used to track abnormal heart rhythms. A pacemaker is able to use electrical impulses to help the heart beat at a normal rhythm. Pacemakers are typically used to treat arrhythmias, which are irregularities in the heart’s rhythm.

An implantable cardioverter defibrillator is a tiny electrical generator that is implanted in patients with ventricular fibrillation and tachycardia. The device corrects cardiac arrhythmia by delivering an electric jolt.

Stress test

An exercise electrocardiogram (EKG or ECG) is an outpatient test that checks for changes in your heart while you exercise. Your physician may order this test to check any abnormalities that can be seen in the EKG only during exercise or while symptoms are present. This test is sometimes called a “stress test” or “treadmill test.”

A resting EKG is always done before an exercise EKG test, and the results of both test are compared. A resting EKG may also show a heart problem that would make an exercise EKG unsafe.

Mitral valve repair

Mitral valve replacement is the best option for nearly all patients with a leaky mitral valve and for many with aortic stenosis. 

Compared to valve replacement, mitral valve repair provides:

  • Better preservation of heart function
  • Lower risk of complications
  • Usually eliminates the need for long-term use of blood thinners (anticoagulants)

Advantages of mitral valve repair:

  • Better early and late survival
  • Improved lifestyle
  • Lower risk of stroke and infection (endocarditis)
