Cardiac catheterization is a medical procedure used to diagnose and treat certain heart conditions. It provides doctors with a detailed view inside the heart and its blood vessels. With this procedure, they gather information that helps them understand your specific heart issue and develop a personalized care plan. Here is more information about the role of cardiac catheterization in treating heart disease:
What Is Cardiac Catheterization?
Cardiac catheterization involves guiding a thin, flexible tube called a catheter to your heart. The catheter is inserted into a blood vessel in your groin, arm, or neck. It is carefully threaded through your blood vessels until it reaches your heart. This allows doctors to perform tests and treatments directly on the heart muscle, valves, or coronary arteries.
During the procedure, a special dye might be injected through the catheter, and X-ray images are taken. This process, called coronary angiography, creates a detailed map of your heart’s arteries. It shows if there are any blockages or narrow spots that could be affecting blood flow. Doctors also use the catheter to measure pressure inside the heart chambers and check how well the heart is pumping. In some cases, a small tissue sample, or biopsy, is taken from the heart muscle for examination.
What Should I Expect During the Procedure?
Before the procedure begins, a local anesthetic will be used to numb the insertion site. You will be awake and able to follow instructions from the medical team. The doctor will make a small puncture to access the blood vessel and insert the catheter. You may feel pressure at the insertion site, but the process of moving the catheter through your blood vessels is typically painless. If a dye is injected, you might feel a warm or flushing sensation that lasts for a few seconds. Throughout the process, a medical team will monitor your heart rate, blood pressure, and oxygen levels.
What Do the Results Reveal?
The information gathered during cardiac catheterization provides a clear picture of your heart’s health. The results show the exact location and severity of any blockages in your coronary arteries. They also reveal how well your heart chambers and valves are functioning.
Measurements of pressure and oxygen levels in different parts of the heart help diagnose conditions like heart failure or congenital heart defects. The procedure may also identify problems with the heart muscle. These detailed findings provide your doctor with the specific information needed to determine the cause of symptoms, such as chest pain or shortness of breath, and to develop a tailored treatment plan.
What Is the Follow-up Treatment?
After reviewing the results, your doctor should discuss the findings with you, and the next steps depend on what was discovered. If a significant blockage is found, your doctor might recommend a treatment to restore blood flow. A common treatment performed during or after catheterization is angioplasty, where a small balloon is inflated inside the narrowed artery to widen it. A small mesh tube called a stent is then placed in the artery to help keep it open. Other follow-up actions can include medication adjustments or recommendations for lifestyle changes. In certain situations, the results may indicate the need for bypass surgery.
