Cardiac catheterisation is a diagnostic procedure to detect obstructions or narrowing (stenosis) on the coronary arteries. It gives us information about the functioning of the heart, valves and coronary arteries that can be used to prevent a heart attack or angina.
Cardiac catheterisation consists of introducing a catheter into an artery, usually the radial (wrist puncture) or femoral artery (groin puncture).
The catheter is guided to the heart and contrast liquid is injected to see the heart's chambers, major vessels and its functioning, contractility, etc.
Cardiac catheterisation is performed in the operating theatre under local anesthesia. It usually lasts about 45-60 minutes.
BEFORE THE PROCEDURE
Although this is a diagnostic test, it must be taken precautions similar to those taken in surgical procedures.
Patients should undergo a preliminary test to evaluate the specific characteristics of their intervention.
Furthermore, they must undergo a standard preoperative study that includes blood tests, electrocardiogram, etc.
Also, if they have any chronic illness or regularly take medications, especially anticoagulants, they should inform the surgeon before surgery.
AFTER THE PROCEDURE:
If the insertion zone is the femoral artery (groin), patients must rest in bed with the affected leg stretched out, for 12 hours at least.
Intense sports and efforts are not recommended for the initial two days after cardiac catherisation.
