Cardiovascular imaging and diagnostics in Kissimmee, Florida

If you are experiencing heart issues, it's crucial to get an accurate diagnosis. At the Heart and Vascular Institute at Osceola Regional Medical Center, we can help by providing comprehensive cardiovascular screening and imaging services. Our diagnostic procedures help us identify occurrences inside the heart, so we can offer every patient an expert diagnosis and comprehensive treatment.

Cardiac catheterization (cath) laboratory

Your physician may recommend an exam in our cardiac cath lab to study how your heart is functioning. We perform a number of minimally invasive procedures that review how your blood is flowing, how the heart valves are working and what amount of blood pressure is present in your heart chambers.

Procedures performed during a catheterization include:

  • Left and right heart catheterization—checks the blood flow on both sides of your heart
  • Radial (wrist-approach) cardiac catheterization
  • Coronary angiogram—checks for blockages in your heart
  • Balloon valvuloplasty—opens up narrowed heart valves
  • Stent replacement/deployment

Electrophysiology (EP) lab

Our EP lab is staffed by experts who are highly trained in diagnosing and treating irregular heartbeats (arrhythmias).

Using advanced technology in the EP lab, we are able to review a map of your heart and monitor electrical activity in 3D and real-time. This map helps determine the origin of and best treatment for the arrhythmia.

We specialize in the following arrhythmia procedures:

  • Ablation and cryoablation
  • Atrial fibrillation (AFib) and left atrial appendage closure implant (LAAC)
  • Implantable cardioverter defibrillators
  • Implantable defibrillators
  • Lead management systems
  • Pacemaker insertion and monitoring

Cardiac tests we offer

Effective heart care starts with an accurate diagnosis, which is why we provide the latest advancements in heart testing. Some of our cardiac exams and imaging include:

Cardiac CT Scan/CT Angiography

This rapid imaging technology allows a virtual, non-invasive diagnostic catheterization procedure using an 80mm 256 slice CT. Produces low dose radiation and is the only diagnostic imaging technology of its kind in Central Florida.

Doppler ultrasound

This noninvasive test uses Doppler technology to measure the changes in pitch (or frequency) that your blood cells create when they move through your body. This specialized technology helps check blood pressure in the arteries and detect blood flow problems and clots.


This noninvasive test uses sound waves to create images of your heart. showing how your heart is beating and pumping blood.

Transthoracic echocardiogram

This type of echocardiogram aims an ultrasound toward your heart and records sound wave echoes, which are then converted into images.

Transesophageal echocardiogram

If clear images can't be collected via a standard echocardiogram, a transesophageal echocardiogram can be used to gather ultrasound images of your heart from inside your esophagus.

Electrocardiogram (EKG or ECG)

This noninvasive test measures the electrical activity of the heart. You may need an EKG if you are experiencing chest pain, heart palpitations, shortness of breath or dizziness. You may also have an EKG as part of a routine physical, during a stress test or prior to heart surgery.

Ejection fraction (EF)

EF numerically measures the percentage of blood that leaves the heart with each beat or "contraction." A high EF number might mean you’re at risk for certain heart conditions, including hypertrophic cardiomyopathy. A low EF number might mean you have a weak, enlarged, thickened or stiffened heart.

EF is most commonly measured during an echocardiogram. It can also be measured during:

  • Cardiac catheterization
  • Computerized tomography (CT) scans
  • Magnetic resonance imaging (MRI)
  • Nuclear medicine scans

Percutaneous coronary intervention (PCI)

A PCI is also known as a "coronary angioplasty." The procedure is similar to cardiac catheterization. It is used to open (and keeping open) a clogged artery.

Radial ST-elevation myocardial infarction (STEMI)

A STEMI is a heart attack. It involves a blockage in one of your heart's primary arteries. A radial STEMI, or transradial procedure, is a cardiac catheterization surgery performed in select patients through the wrist's radial artery. This procedure tends to cause less bleeding than a groin insertion treatment, and allows you to begin walking and return to normal activities quicker.

Stress testing

We offer a variety of stress tests to evaluate your heart health. The main stress test we perform is an exercise stress test. During this evaluation, you will walk on a treadmill or ride a stationary bike while technicians monitor your breathing, heart rhythm and blood pressure.

Since your heart has to pump harder than usual, the test will reveal problems that may not otherwise be noticed. The stress test can be done in conjunction with an ultrasound, to closely watch your blood flow during the procedure.

Vascular ultrasound

A vascular ultrasound uses high-frequency sound waves to examine the blood circulation in your arms and legs. It can help evaluate blood flow in the arteries, blood flow to a newly transplanted organ and blood flow that indicates narrowed areas of the arteries.
