Cardiac catheterization is a medical procedure that involves inserting a thin, flexible tube called a catheter into a blood vessel in the arm, groin, or neck and guiding it to the heart. This procedure is commonly used to diagnose and treat heart conditions such as coronary artery disease, heart valve problems, and congenital heart defects.
Cardiac catheterization is an essential diagnostic tool for many heart conditions as it allows doctors to see the blood vessels and chambers of the heart and get measurements of the pressure inside the heart. In addition, the procedure can also be used to treat certain heart conditions, such as opening up blocked blood vessels with stents or repairing damaged heart valves.
Despite the benefits of cardiac catheterization, the procedure comes with risks and complications. These risks include bleeding, infection, allergic reaction, damage to blood vessels or the heart, stroke, and radiation exposure. Complications can also arise from the procedure, such as arrhythmias, blood clots, kidney damage, contrast dye reaction, and vascular complications.
It is important for patients to understand these risks and complications and discuss them with their doctor before undergoing the procedure. By understanding the potential risks and complications, patients can make informed decisions about their healthcare and take appropriate measures to minimize their risks.
Cardiac catheterization is a minimally invasive medical procedure that involves the insertion of a catheter into a blood vessel to access the heart. While the procedure is generally safe, it is not without risks. In this section, we will discuss the risks of cardiac catheterization in more detail.
Bleeding and Hematoma
One of the most common risks associated with cardiac catheterization is bleeding. During the procedure, a small incision is made to insert the catheter, and this can lead to bleeding. Sometimes, a hematoma, or a collection of blood, can form around the insertion site. This can be painful and may require further treatment.
Another risk of cardiac catheterization is infection. Since the procedure involves accessing the bloodstream, there is a risk of infection. The risk of infection is typically low, but it is important to take precautions to minimize this risk.
Some patients may have an allergic reaction to the contrast dye used during the procedure. This can lead to symptoms such as hives, itching, and difficulty breathing. If you have a history of allergies, it’s important to discuss this with your doctor before the procedure.
Damage to Blood Vessels or Heart
In rare cases, cardiac catheterization can cause damage to the blood vessels or the heart. This can occur if the catheter accidentally punctures a blood vessel or if it causes damage to the heart muscle. These complications can be serious and require immediate medical attention.
Stroke or Heart Attack
Another rare but serious complication of cardiac catheterization is stroke or heart attack. These complications can occur because of the use of contrast dye or if a blood clot forms during the procedure.
Finally, cardiac catheterization exposes patients to a small amount of radiation. While the amount of radiation is generally considered safe, it’s important to be aware of this risk and take precautions.

While cardiac catheterization is generally considered safe, certain factors can increase the risk of complications. In this section, we will discuss some factors that can increase the risk of complications during or after cardiac catheterization.
Age and Overall Health
Older adults and those with pre-existing health conditions are at an increased risk of complications from cardiac catheterization. This is because their bodies may not be able to handle the stress of the procedure as well as younger, healthier individuals.
Pre-existing Medical Conditions
Certain medical conditions, such as kidney disease, diabetes, and heart disease, can increase the risk of complications from cardiac catheterization. If you have a pre-existing medical condition, your doctor will take this into consideration when determining if cardiac catheterization is appropriate for you.
Medications and Allergies
Certain medications and allergies can increase the risk of complications during cardiac catheterization. For example, if you are taking blood-thinning medications, you may be at an increased risk of bleeding during the procedure. It’s important to discuss any medications and allergies with your doctor prior to the procedure.
Obesity can make it more difficult to perform cardiac catheterization and can increase the risk of complications such as bleeding and infection. If you are overweight or obese, your doctor may recommend losing weight prior to the procedure to reduce your risk of complications.
Smoking and Alcohol Consumption
Smoking and alcohol consumption can increase the risk of complications during and after cardiac catheterization. Smoking can increase the risk of bleeding and damage to the blood vessels, while alcohol consumption can interact with medications used during the procedure. If you smoke or consume alcohol, your doctor may recommend abstaining prior to the procedure.
There are several precautions that patients can take to help minimize the risk of complications during or after cardiac catheterization. In this section, we will discuss some precautions that patients can take before and after the procedure.
Pre-procedure Evaluation and Testing
Before undergoing cardiac catheterization, patients will undergo a pre-procedure evaluation to assess their overall health and identify any factors that may increase their risk of complications. This may include blood tests, electrocardiograms (ECGs), and imaging tests such as echocardiograms or angiograms.
Depending on the patient’s individual circumstances, their doctor may prescribe medications to help minimize the risk of complications during or after the procedure. For example, patients may be given anti-clotting medications to reduce the risk of blood clots or medications to help protect the kidneys from the contrast dye.
Post-procedure Care and Monitoring
After cardiac catheterization, patients will typically be monitored in the hospital for a few hours to ensure that there are no complications. Patients will be instructed to avoid strenuous activity for several days following the procedure and to keep the insertion site clean and dry.
Besides the risks associated with cardiac catheterization discussed in the previous section, there are also potential complications that can arise from the procedure. In this section, we will discuss some complications that can occur during or after cardiac catheterization.
Arrhythmias are abnormal heart rhythms that can occur during or after cardiac catheterization. These can be caused by the catheter irritating the heart muscle or by changes in blood flow during the procedure. Most arrhythmias are minor and resolve on their own, but in rare cases, they can be serious and require medical intervention.
Another potential complication of cardiac catheterization is the formation of blood clots. This can occur because of the catheter irritating the blood vessels or due to changes in blood flow during the procedure. Blood clots can be dangerous if they travel to other parts of the body, such as the lungs or brain.
The contrast dye used during cardiac catheterization can be harmful to the kidneys, particularly in patients with pre-existing kidney problems. In some cases, this can lead to acute kidney injury, which can be serious and require medical treatment.
Contrast Dye Reaction
Some patients may have an allergic reaction to the contrast dye used during the procedure. This can lead to symptoms such as hives, itching, and difficulty breathing.
Cardiac catheterization can cause damage to the blood vessels, which can lead to vascular complications such as bleeding, hematoma, or aneurysm.
In conclusion, cardiac catheterization is an important diagnostic and treatment tool for many heart conditions. While the procedure comes with risks and potential complications, these risks can be minimized through precautions and careful monitoring. It’s important for patients to discuss the potential risks and benefits of cardiac catheterization with their doctor before undergoing the procedure. By working closely with your doctor, you can ensure that you receive the best possible care and achieve the best possible outcomes.

Invasive therapies may also be used to treat an abnormal heart rhythm, such as electrical cardioversion which sends electrical impulses through your chest wall and allows normal heart rhythm to restart, or catheter ablation which disconnects the pathway of the abnormal rhythm. If your doctor determines that electrical devices are the best course of action, you may be given a permanent pacemaker, an implantable cardioverter-defibrillator (ICD), or biventricular (B-V) pacemakers and defibrillators.
CVG offers a variety of services that can check and treat causes of fainting. At CVG, we perform stress tests that will observe blood flow and test for Atrial Fibrillation. There are three types of stress tests that we perform:
A treadmill test is a test in which you will walk on a treadmill that gets faster and steeper every 3 minutes. This will stress your heart so that our nurse or doctor can determine your EKG and blood pressure.
An echo test is performed before and after your treadmill test to determine how well your heart pumps blood.
A nuclear stress test is a treadmill test that is prefaced by an injection of medicine that shows the flow of blood to your heart.
We also offer cardiac catheterization, in which a catheter is inserted into the heart in order to take pictures and conduct tests. This procedure allows doctors to gain more information about your condition and suggest treatment options if the fainting episode is due to heart conditions.
If these tests determine a problem, we offer treatment solutions to fix several conditions. Learn more about our services here, or schedule an appointment to talk to our doctors.
