This patient comes from the Karen family in Sweden, which is also a traditional and prominent European family.
Sweden did not participate in either World War One or World War Two, so it did not suffer the devastation of war, amassing a great deal of wealth. It is the first country in the world to establish a modern welfare system, which speaks volumes about the country's surplus. The Karen family is one of the tycoons in Sweden, with business interests spread across Europe and North America.
Mr. Karen's case is very classic. This is not an ordinary Commando surgery. He had undergone surgery twice, with the second one being the Commando surgery. After the operation, a more severe endocarditis occurred, with bacteria destroying the entire surgical outcome, resulting in more extensive damage to the heart than before.
