Cardiac catheter examinations (so-called diagnostic cardiac catheterizations) display the coronary vessels. To do so, we insert the catheter (a narrow plastic tube) usually via the right radial artery up to the coronary vessel. When we let a contrast agent flow through the catheter, we can see the coronary vessels on the X-ray screen. While this contrast agent flows into the coronary vessels, they are filmed from various perspectives. Following a diagnostic cardiac catheterization, we often perform a balloon dilatation and/or stent implantation. When severe constrictions of all three cardiac coronary vessels are discovered, it may be necessary to perform a surgical bypass.
We conduct the cardiac catheterizations ourselves, so we can tell you all about the process and risks of the procedure. Normally, we choose the gentle route of entering the vascular system via the radial artery because only a little bed rest is required after the examination plus complications in the blood vessels occur less commonly.
