Cardiac catheterization, also known as coronary angiography, is a medical procedure used to diagnose and treat heart conditions. During this procedure, a thin, flexible tube called a catheter is inserted into a blood vessel in the arm or groin and threaded through to the heart. Cardiac catheterization allows doctors to assess the functioning of the heart and its blood vessels, as well as to carry out various therapies to treat heart diseases.
One of the most common reasons for cardiac catheterization is to check for blockages or narrowing in the coronary arteries, which can cause chest pain, heart attacks, or other heart-related problems. By injecting a contrast dye through the catheter, doctors can visualize the flow of blood through the coronary arteries and identify any blockages or other abnormalities. This information helps them determine the best course of action for the patient, whether it be medication, angioplasty, or bypass surgery.
Cardiac catheterization can also be used to measure the pressure and oxygen levels inside the heart, diagnose congenital heart defects, or assess the function of heart valves. In some cases, the procedure is used to perform treatments such as balloon angioplasty, stent placement, or ablation therapy.
Before the procedure, patients will typically undergo some tests to assess their overall health and the condition of their heart. They may need to fast for a period of time before the procedure, and they will receive sedation to help them relax during the catheterization.
During the procedure, patients are awake but will likely feel little to no discomfort, as the catheter is guided through the blood vessels to the heart. The entire procedure typically takes 30 minutes to an hour, but may take longer if treatments are performed.
After the cardiac catheterization, patients are usually monitored for a few hours to ensure that there are no complications. Most patients are able to return to their normal activities within a day or two. It is important to follow the doctor’s instructions for post-procedure care, which may include taking medications, avoiding strenuous activities, and keeping the catheter insertion site clean and dry.
While cardiac catheterization is generally considered a safe and effective diagnostic and treatment tool, it does carry some risks, such as bleeding, infection, or damage to the blood vessels or heart. However, these risks are relatively low and can be minimized with proper preparation and experienced medical care.
In conclusion, cardiac catheterization is a valuable tool for diagnosing and treating heart conditions. By allowing doctors to visualize the heart and its blood vessels, they can provide patients with the most appropriate and effective treatments. If you have concerns about your heart, speak with your doctor to see if cardiac catheterization may be right for you.
