Cardiac catheterization is an invasive examination of the heart. With it, the cardiologist can diagnose a variety of diseases and possibly even treat the same.
In a cardiac catheterization, a thin, flexible plastic tube (cardiac catheter) is advanced over a vessel to the heart. The doctor usually selects a vessel in the groin or on the wrist. Inserting the catheter is also what doctors call "heart catheterization" or "heart catheterization". A contrast agent can be injected via the tube to make the heart structures and vessels more visible on the X-ray image.
In addition, the heart catheter can be used to measure various parameters (pressures and flow velocities in the heart) that provide information about the heart muscle's workforce. Sometimes a cardiac catheterization is also used to extract a tissue sample from the heart (myocardial biopsy).
Cardiac catheterization is roughly subdivided into two procedures - depending on which half of the heart is being examined: left heart catheter and right heart catheter.
