Cardiac Catheterization & Expert Cardiologists

Our Cardiac Catheterization Lab Helps Diagnose and Treat Heart Conditions

What Is a Cardiac Catheterization?

Cardiac catheterization is a procedure used to diagnose and treat a wide variety of heart and cardiovascular conditions. This procedure involves passing a thin flexible tube (catheter) into the right or left side of the heart, usually from the groin or the arm. This technique allows our expert team of cardiologists in our cardiac catheterization lab to diagnose and treat conditions like coronary artery disease, valve disease, vascular disease, heart failure, arrhythmias, and congenital heart defects, among others.

Is a Heart Catheterization Major Surgery?
No. A cardiac catheterization is not a major surgical procedure. During a cardiac cath, there are no large incisions, and the chest cavity is not opened. The recovery time from a cardiac catheterization is much shorter than the recovery time from a major surgery.
Heart Attacks: Time is Muscle
Did you know that during a heart attack time=muscle? The faster you receive treatment for a heart attack the more muscle you save. At Conway Medical Center, our team of interventional cardiologists in our cardiac catheterization lab is here to do just that!
The CMC cardiac catheterization lab is now providing a much wider scope of services than ever before. We are able to provide 24-7 support to the community for emergency treatment of myocardial infarction (heart attack) and provide elective treatment for cardiovascular disease.
More patients are now able to stay closer to home and get the care they deserve when they need it.
High-Tech Care
Conway Medical Center was the first health system in the Southeast to introduce the Philips Allura Xper SZ10. This state-of-the-art technology allows us to improve cardiac care, and make earlier and more decisive treatment plans, with the ability to have a comprehensive team involved. During an emergency, our team of experts are able to quickly diagnose and treat, saving lives and heart muscle.
How Is a Cardiac Catheterization Performed?
You will be given a mild sedative before the test to help you relax. An intravenous (IV) line is inserted into one of the blood vessels in your arm, neck, or groin after the site has been cleansed and numbed with a local numbing medicine (anesthetic).
A catheter is then inserted through the IV and into your blood vessel. The catheter is carefully threaded into the heart using an x-ray machine that produces real-time pictures (fluoroscopy).
Once the catheter is in place, your doctor may:
- Collect blood samples from the heart
- Measure pressure and blood flow in the heart’s chambers and in the large arteries around the heart
- Measure the oxygen in different parts of your heart
- Examine the arteries of the heart with an x-ray technique called fluoroscopy (which gives immediate, “real-time” pictures of the x-ray images on a screen and provides a permanent record of the procedure)
- Perform a biopsy on the heart muscle
How Do I Prepare for a Cardiac Catheterization?
How to Prepare for the Test
If possible, you will be asked not to eat or drink for 6 – 8 hours before the test. The test takes place in a hospital in our cardiac catheterization lab, and you will be asked to wear a hospital gown. Sometimes, you will need to spend the night before the test in the hospital. Otherwise, you will be admitted as an outpatient or an inpatient the morning of the procedure.
Your health care provider should explain the procedure and its risks. A witnessed, signed consent for the procedure is required.
Tell your doctor if you:
- Are allergic to seafood
- Have had a bad reaction to contrast material or iodine in the past
- Are taking Viagra
- Might be pregnant
Is a Heart Catheterization Painful?
No. While you may feel a bit of pressure and mild discomfort, you should not feel any pain. We strive to make the entire experience as comfortable as possible for you.
How the Test Will Feel
The study is done by trained cardiologists in our cardiac catheterization lab with the assistance of trained technicians and nurses.
You will be awake and able to follow instructions during the test. You will usually get a mild sedative 30 minutes before the test to help you relax. The test may last 30 – 60 minutes.
You may feel some discomfort at the site where the catheter is placed. Local anesthesia will be used to numb the site, so the only sensation should be one of pressure at the site. You may experience some discomfort from having to remain still for a long time.
After the test, the catheter is removed. You might feel a firm pressure, used to prevent bleeding at the insertion site. If the catheter is placed in your groin, you will usually be asked to lie flat on your back for a few hours after the test to avoid bleeding. This may cause some mild back discomfort.
Why Do I Need a Cardiac Catheterization?
Why the Test is Performed
In general, this procedure is done to get information about the heart or its blood vessels or to provide treatment in certain types of heart conditions. It may also be used to determine the need for heart surgery.
Your doctor may perform cardiac catheterization to:
- Diagnose or evaluate coronary artery disease and/or a heart attack
- Diagnose or evaluate congenital heart defects
- Diagnose or evaluate problems with the heart valves
- Diagnose causes of heart failure or cardiomyopathy
The following may also be performed using cardiac catheterization:
- Repair of certain types of heart defects
- Repair of a stuck (stenotic) heart valve
- Opening of blocked arteries or grafts in the heart
What Do Abnormal Results Mean?
The procedure can identify heart defects or disease, such as:
- Coronary artery disease
- Valve problems
- Ventricular aneurysms
- Heart enlargement
The procedure also may be performed for the following:
- Primary pulmonary hypertension
- Heart valve defects, such as:
  - Pulmonary valve stenosis
  - Mitral valve regurgitation
  - Aortic stenosis
  - Other heart valve disorders
- Pulmonary embolism
- Birth defects, such as:
  - Tetralogy of Fallot
  - Transposition of the great vessels
  - Ventricular septal defect
  - Coarctation of the aorta,
  - Other birth defects
- Cardiac amyloidosis
What Are the Risks Associated with Cardiac Catheterization?
Cardiac catheterization carries a slightly higher risk than other heart tests, but it is very safe when performed by an experienced team like the one in our cardiac catheterization lab.
Generally, the risks include the following:
- Cardiac arrhythmias
- Cardiac tamponade
- Heart attack
- Bleeding
- Low blood pressure
- Reaction to the contrast medium
- Stroke
- Trauma to the artery caused by hematoma
Possible complications of any type of catheterization include the following:
- A risk of bleeding, infection, and pain at the IV site
- A very small risk that the soft plastic catheters could damage the blood vessels
- Blood clots could form on the catheters and later block blood vessels elsewhere in the body.
- The contrast material could damage the kidneys (particularly in patients with diabetes).
