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).
A coronary bypass is the surgical alternative to treat coronary obstructions by cholesterol plaques. It restores blood flow to the heart creating a new route or bypass around the blocked section of the coronary artery.
Coronary bypass improves heart work and prevent future cardiac problems.
Coronary bypass can be performed with extracorporeal circulation or not. Both surgeries are done under general anesthesia and lasts about three or four hours.
