20% of Sudden Deaths Caused by Myocarditis

When our health officials talk about Covid vaccine victims,
we always hear the same story:
 - Deaths are unrelated to vaccination
 - Myocarditis is mild, and nobody dies of it
 - They refuse to autopsy the victims
This gaslighting became an art form for Covid vaccine advocates,
with fact-checkers and social networks suppressing any discussion.
We instinctively know not to trust them, but had no scientifically
validated studies of people who died suddenly after vaccination
 - until now. A study of victims of sudden post-vaccine deaths by
pathologists at the University of Heidelberg was published
(https://bit.ly/3HfjYmw) in Clinical Research in Cardiology.
The study is very interesting in that university pathologists got
hold of 25 bodies of previously healthy people who "suddenly
died" within 20 days of Covid vaccination. 
 - Here, we describe the cardiac autopsy findings in five persons
who have died unexpectedly within seven days following
anti-SARS-CoV-2-vaccination, with vaccine-induced myocardial
inflammation representing the likely or possible cause of death.
Our findings establish the histological phenotype of lethal
vaccination-associated myocarditis.
 - Standardized autopsies were performed on 25 persons who had
died unexpectedly and within 20 days (20 days was the study
parameter - they died within 7 days - I.C.) after anti-SARS-CoV-2
vaccination.
 - Cardiac autopsy findings consistent with (epi-)myocarditis were
found in five cases of the remaining 25 bodies found unexpectedly
dead at home within 20 days following SARS-CoV-2 vaccination.
So, 20% of all "sudden deaths" happening shortly after COVID
vaccination are caused by myocarditis.
Had they not been autopsied by the University of Heidelberg
pathologists, they would NEVER have a diagnosis of myocarditis.
I want to ask the following questions:
 - Why doesn’t the CDC perform (or arrange to perform) autopsies?
 - Why do the CDC and fact checkers claim that myocarditis does
NOT cause deaths if they do not even autopsy vaccine victims?
 - How can fact-checkers be believed if they do not have any data
to back up their fact-checks?
Our authorities claim that "myocarditis does not cause deaths" for
only one reason: they refused to autopsy vaccine victims. As soon
as autopsies of a representative sample of "sudden deaths" were
finally done, as in the above Heidelberg study, it turned out that
20% of sudden deaths were myocarditis-related.
