Cardiac Catheterization

Overview

Cardiac catheterization, also known as heart catheterization, is a medical procedure used to diagnose and treat heart conditions. A thin flexible tube called a catheter is inserted into a blood vessel and guided to the heart to check for blockages, measure heart function, and even perform treatments like placing a stent. This cardiac catheterization procedure helps doctors assess heart health and provide necessary treatment in a minimally invasive way.

Why Cardiac Catheterization is Required?

Doctors recommend heart cath procedures for various reasons, such as:

• Checking for blocked or narrowed arteries (coronary angiogram).
• Measuring the pressure inside the heart chambers (left heart catheterization or right heart catheterization).
• Evaluating how well the heart is pumping blood.
• Diagnosing heart valve disease or congenital heart defects.
• Treating certain heart conditions by inserting stents or balloons.
• Determining if a person needs bypass surgery.

Key Advantages of Cardiac Catheterization

• Minimally invasive: No major surgery is required.
• Quick recovery: Most patients go home the same day.
• Accurate diagnosis: Provides clear images of heart function.
• Immediate treatment: Blockages can be treated in the same procedure.
• Detects blood clots: It can help identify clots that could cause strokes.

How Should You Prepare Yourself Before Taking Cardiac Catheterization Treatment?

• Follow doctor’s instructions regarding eating and drinking before the procedure.
• Inform doctor about any allergies, especially to iodine or contrast dye.
• Discuss all medications, especially blood thinners or diabetes medications.
• Arrange for someone to drive home after the procedure.
• Wear comfortable clothes and remove any jewelry before the procedure.

How Cardiac Catheterization is Performed?

• The patient is given a mild sedative to relax.
• A local anesthetic is applied to numb the insertion site (wrist or groin).
• The doctor inserts a catheter into a blood vessel and guides it to the heart using X-ray imaging in a cath lab.
• Contrast dye is injected to make the arteries visible on the screen.
• Depending on findings, additional procedures like angioplasty or stent placement may be performed.
• Once done, the catheter is removed and pressure is applied to prevent bleeding.

What You Can Expect?

1. Before the Procedure

• You will be given instructions about eating, drinking, and medications.
• The doctor will explain the risks and benefits.
• A mild sedative may be given to help you relax.

2. During the Procedure

• You may feel mild pressure but no severe pain.
• The contrast dye may cause a warm sensation.
• You will be awake and able to communicate with the medical team.

3. After the Procedure

• You will be monitored for a few hours.
• You may need to lie flat if the catheter is inserted in the groin.
• Most patients go home the same day but need to rest.

Risk and Potential Complications

While cardiac catheterization risks are minimal, potential complications include:

• Bleeding or bruising at the catheter site.
• Infection.
• Blood clots that could lead to a stroke.
• Risk of death during stent procedure (though very rare).
• Allergic reaction to the contrast dye.
• Arrhythmias (irregular heartbeat).

Results/Outcomes

If blockages are found, a treatment plan will be discussed.

Some blockages can be treated immediately with stents or angioplasty.

If severe blockages are found, bypass surgery may be recommended.

Patients with no major blockages can continue with lifestyle changes and medications.
