It was earlier this summer that the health care visit in question took place.
In the report, it can be read that a vessel near the heart burst when the doctor inserted a balloon incorrectly.
Balloon is used in so-called balloon dilation, a treatment that is sometimes applied when narrowings have occurred in the coronary arteries of the heart.
In this case, the balloon must have been inserted so that it ended up between the innermost and middle vessel walls, something that must have caused a vessel to burst.
As a result, the blood supply to the heart must have been cut off to part of the heart, which in turn caused a massive heart attack, according to the report.
The patient states that this also affected the heart's pumping ability and treatment for permanent heart failure was started.
Ivo is now expected to make a decision on whether this should be investigated or not.
