OPS-Code 3-05g.0:

Your coronary arteries have been examined from the inside using ultrasound.

An ultrasound examination involves sending ultrasound waves from an ultrasound probe in the body. Depending on the structure of the tissue, different numbers of ultrasound waves are reflected. These waves are then converted to images that can be viewed on a screen. To use ultrasound to closely examine tissue or organs, the ultrasound probe should be as close as possible to the location being examined. For this purpose, the ultrasound probe can be inserted into the body using a tube.

The heart muscle is supplied with oxygen-rich blood via the coronary arteries. The coronary arteries are blood vessels that run around the outside of the heart.

To examine your coronary arteries from the inside, the ultrasound probe was inserted into a blood vessel via a catheter. A catheter is a thin tube. This tube is inserted into a blood vessel in the groin or arm, for example, and pushed further in. Various instruments can be pushed onto the tip of the tube.
