What Is Cardiac Catheterization?
Chest pain that won’t go away, an abnormal stress test result, or a cardiologist mentioning the word “catheterization” for the first time it’s natural to want a plain explanation before you agree to any procedure. Cardiac catheterization, often called a heart cath, is a procedure that lets your cardiologist look directly at your coronary arteries using a thin, flexible catheter guided through a blood vessel, usually in the wrist or groin, rather than through open surgery.
At FHVI’s outpatient cath labs, the same visit that diagnoses a blockage can often treat it too. Your interventional cardiologist injects contrast dye and takes live X-ray images (coronary angiography) to see exactly where and how severe a blockage is. If a treatable blockage is found, angioplasty and stent placement can follow immediately, meaning one appointment covers both the answer and the fix.
Diagnostic Cardiac Catheterization
The definitive test for coronary artery disease. Contrast dye and live X-ray imaging show exactly where an artery is narrowed and how severe the blockage is, when non-invasive tests like a stress test aren’t conclusive enough.
Coronary Angiography
The imaging portion of the procedure. A coronary angiogram produces a detailed picture of the coronary arteries, the gold standard for confirming and locating blockages.
Angioplasty and Stent Placement (PCI)
When a blockage is found and treatable, a small balloon opens the narrowed artery (angioplasty) and a stent, a mesh tube, holds it open. This is percutaneous coronary intervention (PCI), typically performed in the same session as the diagnostic catheterization.
Wrist vs. Groin Access
FHVI’s preferred approach is radial (wrist) access, which carries a lower bleeding risk and allows faster mobility than traditional femoral (groin) access. Your cardiologist will discuss which approach is right for your anatomy.
When You May Need Cardiac Catheterization
Cardiac catheterization is usually recommended after other tests point toward a possible blockage, or when urgent evaluation is needed. Some symptoms warrant same-week evaluation; others are appropriate for a scheduled workup.
Get tested urgently, if you have:
- Chest pain or pressure (angina) at rest or with minimal activity
- Suspected or confirmed heart attack
- An abnormal or inconclusive stress test result
- New or worsening shortness of breath with a known heart condition
- Unexplained heart failure with reduced pumping function
- Elevated cardiac enzymes (troponin) found on recent bloodwork
Get screened proactively, if you have:
- Known coronary artery disease needing follow-up evaluation
- Angina that occurs predictably with exertion and eases with rest
- Prior stents or bypass surgery requiring reassessment
- Multiple cardiac risk factors (diabetes, high blood pressure, high cholesterol, smoking) and new symptoms
Emergency Warning
Chest pain that doesn't resolve, pain spreading to the arm, jaw, neck, or back, sudden severe shortness of breath, or cold sweat with chest discomfort may be a heart attack. Call 911 immediately. Do not drive yourself.
Cardiac Catheterization Risks and Benefits
Cardiac catheterization is a well-established, generally safe procedure performed on an outpatient basis at FHVI. Understanding the risk-benefit picture helps you make an informed decision.
Benefits
- A definitive diagnosis direct visualization removes the guesswork of non-invasive testing
- Same-visit treatment many blockages are treated in the same session as diagnosis
- Outpatient convenience most patients go home the same day, not overnight in a hospital
- Faster recovery with radial (wrist) access compared to traditional groin access
- Board-certified interventional cardiologists close to home in Ocala
Risks
- Bruising or minor bleeding at the access site: most common, generally minor
- Allergic reaction to contrast dye: uncommon, screened for beforehand
- Blood vessel damage: rare
- Irregular heart rhythm during the procedure: rare, monitored continuously
- Heart attack or stroke: very rare
- Infection at the catheter access site — rare, and reduced further by sterile technique
- Kidney stress from contrast dye — uncommon, monitored closely in patients with existing kidney disease
Have Chest Pain or an Abnormal Stress Test Result?
FHVI’s board-certified interventional cardiologists perform outpatient cardiac catheterization at our Ocala cath labs.
Cardiac Cath Procedures at FHVI
Every procedure below is available at FHVI’s outpatient cath labs without an outside referral.
Echocardiogram (Echo)
Uses ultrasound to evaluate your heart's chambers, valves, pumping strength, and ejection fraction. Available as transthoracic (TTE) or transesophageal (TEE) studies depending on your condition.
Electrocardiogram (EKG)
Records your heart's electrical activity to detect abnormal rhythms, previous heart attacks, and conduction disorders.
Exercise Stress Test (Treadmill)
Measures how your heart performs during exercise to evaluate blood flow, rhythm changes, and exercise tolerance.
Nuclear Stress Test
Uses a small amount of radioactive tracer to compare blood flow to your heart at rest and during stress, helping identify blocked arteries.
Stress Echocardiogram
Combines ultrasound imaging with exercise or medication induced stress to evaluate heart muscle function and blood flow.
Holter Monitor
Continuously records your heart rhythm during normal daily activities to detect intermittent rhythm abnormalities.
Event Monitor
Records your heart rhythm during symptoms or automatically when an abnormal rhythm occurs, helping diagnose infrequent heart rhythm problems.
Implantable Loop Recorder
A small device placed under the skin continuously monitors your heart rhythm for up to three years to detect unexplained fainting or rare arrhythmias.
Coronary Calcium Score
A specialized CT scan that measures calcium buildup in your coronary arteries to assess your future risk of heart disease.
CT Coronary Angiography (Cardiac CTA)
Uses contrast enhanced CT imaging to produce detailed pictures of your coronary arteries without requiring cardiac catheterization.
Cardiac MRI
Provides detailed images of your heart muscle, valves, and surrounding structures without radiation, helping diagnose many complex heart conditions.
Carotid Duplex Ultrasound & Vascular Studies
Uses ultrasound to evaluate blood flow in the carotid arteries, leg arteries and veins, or abdominal aorta to detect narrowing, blockages, aneurysms, or blood clots.

Frequently Asked Questions
Cardiac catheterization, or a heart cath, is a procedure that lets your cardiologist look directly at your coronary arteries using a thin catheter guided through a blood vessel, usually in the wrist or groin, to diagnose and often treat blockages.
A diagnostic-only catheterization takes 20 to 40 minutes. Adding stent placement typically adds 30 to 60 minutes. Plan for 2 to 4 hours total at the cath lab including preparation and recovery.
With radial (wrist) access, most patients go home the same day and resume light activity within 24 to 48 hours. Avoid heavy lifting for 5 to 7 days after the procedure.
Risks include bruising or bleeding at the access site, a small risk of allergic reaction to contrast dye, and rare risks such as blood vessel injury or heart attack. Your cardiologist reviews your individual risk beforehand.
Radial (wrist) access has a lower bleeding risk and faster recovery, allowing most patients to sit up within an hour. Femoral (groin) access is used when radial access isn’t suitable for your anatomy.
Yes. If a treatable blockage is found during the diagnostic portion of the procedure, angioplasty and stent placement are typically performed in the same session, avoiding a second procedure.
You receive local anesthesia at the access site and a sedative. Most patients feel pressure or warmth rather than pain, and many have little memory of the procedure afterward.
A diagnostic catheterization identifies blockages through coronary angiography. PCI (angioplasty and stenting) treats the blockage. FHVI performs both in the same session where possible.
Your FHVI cardiologist gives specific instructions — blood thinners are often paused, and metformin is typically stopped 48 hours before if contrast dye is used.
Yes. Because of sedation, you’ll need someone to drive you home after your cardiac catheterization.
Yes. FHVI operates outpatient cath labs at our Ocala SW 17th Street and SW 62nd Court locations, in addition to our Davenport cath lab.
FHVI accepts referrals from primary care physicians and cardiologists, and also sees patients directly for an initial consultation to determine if catheterization is appropriate.
Yes. FHVI accepts Medicare, Medicaid, and most major commercial insurance plans. Call 352-619-2550 to verify your specific coverage.
