A medical procedure is used to diagnose and treat certain cardiovascular diseases.
Cardiac catheterization rarely causes serious complications.
It is done to diagnose or treat some problems of valves and arteries of the heart.
Make sure to follow the doctor’s instructions before, during, and after the operation.
The person is often awake during the operation, rarely requiring general anesthesia.
A common medical procedure, rarely causing serious complications, is used to examine and evaluate the function of the heart arteries, valves, and myocardium as well as to treat some of their diseases, by inserting a thin, hollow tube (catheter) that is directed through blood vessels, either into the arms or the thigh, including taking x-rays of coronary arteries that supply blood to the heart muscle.
Diagnosis of narrowed or blocked coronary arteries with a waxy substance (plaque).
Assessment of the degree of valvular heart disease and the assessment of some cardiac muscle functions.
Assessment of some cardiac muscle functions. Conducting therapeutic intervention for narrowed or clogged arteries.
Measurement of the oxygen content in the heart chambers.
A biopsy of heart tissue is taken for examination under a microscope.
Ultrasound can be used during cardiac catheterization, to accurately assess the degree of blockage in the coronary arteries.
During this procedure, more than one cardiac catheter is placed in the arteries and veins of the groin and neck, and the doctor directs radio waves through this catheter.
Heart valve replacement:
During this procedure, the damaged valve is removed using a catheter and then replaced with an artificial valve.
Mechanism of action:
A local anesthetic is given to numb the needle puncture site.
A thin tube (catheter) is inserted into a blood vessel, often from the groin or arm.
The catheter is delivered to the arteries of the heart.
View the position of the catheter as it overlaps the blood vessels through the screen.
When the catheter is in place, a small amount of a certain dye will be injected; To illustrate the coronary arteries.
It is a non-surgical treatment used to open the narrow coronary arteries to improve heart perfusion and can be done at the same time as a diagnostic cardiac catheter, or another appointment, with a balloon and stent placed if the patient needs it.
Preparations before a cardiac catheterization:
- Tell your doctor about any medications you are taking.
- Make sure to do all the necessary tests before performing a cardiac catheterization.
- Follow the doctor’s instructions about abstaining from eating and drinking at least 4 hours before the procedure.
- You should discuss with your doctor when you are allergic to certain substances, especially iodine and others.
When should you see a doctor after cardiac catheterization?
Within a week to make sure the wound has healed. When there is bleeding from the catheter site.
Unusual pain, swelling, redness, or other signs of infection near the catheter site.
Feet feeling cold or turning blue.
Talk to your doctor about whether certain activities such as weightlifting should be avoided for a short time after the catheterization.
Frequently asked questions (needs to be answered by a specialist) Will the person be awake during the cardiac catheterization procedure?
Yes, a person will receive a sedative and the physician will use a local anesthetic to anesthetize the site of catheter insertion, a cardiac catheter is not a major operation, as there is no large incision used to open the chest, and the recovery time is much shorter than open-heart surgery.
How long does cardiac catheterization often take?
Diagnostic cardiac catheterization usually takes about 30 minutes, and treatment may take an hour or more.
Is there a possibility to repeat it again? Yes, if the patient needs it.
Are there side effects or serious complications to it?
Yes, it’s a rare complication of cardiac arrest, or cardiac or brain stroke, which is less than one case per 100,000.
How safe is it for the elderly?
It is safe, and the benefits and harms must be weighed for each case.
Are there alternative procedures to it?
For diagnosis, a CT scan of the arteries may be used, which is less accurate than diagnostic cardiac catheterization.
