How does a cardiac catheter examination work in our clinic?
We want you to feel comfortable in our cardiac catheter laboratory. We therefore ensure a particularly calm atmosphere and support you – in addition to local anesthesia at the injection site – with anxiolytic and calming medication before the examination begins. If these aids are effective, our doctor will insert the heart catheter into your arm or leg artery via the puncture site and carefully push it to the heart. Contrast medium is injected into the coronary arteries via the catheter. The images resemble a tree with many large and many small branches. When the examination is finished, the heart catheter is removed from the blood vessel again and the injection site is treated with a pressure bandage. This pure diagnosis takes about 15-30 minutes.
We can also treat constrictions in your blood vessels with the cardiac catheter. Using a so-called guide wire, we first widen these constrictions with a small balloon, which can only unfold in the vessels. We then stabilize the dilated area permanently with a so-called Stent. This vascular support, which can consist of metal or synthetic fibers, resembles the appearance of a curler. The cardiac catheter examination including stent implantation by balloon dilatation lasts between 45 and 60 minutes. In order for the stent to grow in well in the coming months, patients must take certain blood-thinning tablets.
