Your stay in our cardiac catheterisation laboratory
If you are visiting us as an outpatient, you will be welcomed at the circulation laboratory reception and prepared for the examination by our assistants. Inpatients will be brought to us on call with their beds. Before the examination begins, doctors and assistants will review your patient file once again and clarify any open questions with you.
preparation for examination
The nursing staff will then position you as comfortably as possible on the examination table, attach an infusion and ECG cables, and finally cover you with a large sterile cloth.
Next, under local anaesthetic, the doctor will puncture the artery in your wrist or groin (depending on the examination, a vein in the groin may also be punctured) and insert a so-called sheath – the access point through which the entire examination is performed and which prevents blood from escaping from the puncture site.
investigation
Various catheters are then inserted into the aorta via a guide wire and from there into the coronary arteries. Several doses of contrast medium are administered to make the vessels and any narrowings (stenoses) or other pathological changes visible on the X-ray image and record them.
If necessary, stenoses can in most cases be removed during the same session by means of balloon dilatation and treated with vascular supports (stents), or they may require further cardiac catheterisation.
The doctor performing the procedure will inform you about each step of the examination, and you can follow the examination on the monitor.
Completion of the investigation
At the end of the examination, all catheters and wires are removed, the sheath is pulled out and the puncture site is treated. On the wrist, this is done using a wristband; in the groin, the puncture site is sealed with a closure system and sutured.
Depending on the access route and the closure system used, you may not need to remain in bed at all or you may need to remain in bed for four hours. You will remain in our monitoring room for approximately half an hour until your findings have been evaluated and documented. Our transport service will then take you back to your room.
