The vaccine could cause an immune reaction which leads to heart inflammation. The heart inflammation could result in fibrillation due to damaged pacemaker cells from the inflammation. Fibrillation, I believe, can lead to rupture.

Not that I have done autopsies myself to prove this, but it's conceivable.

Dr. Ryan Cole has entered the chat.

Seriously, he just gave a talk using a ruptured Aorta as an example. They found the wall was attacked by lymphocytes and infused with spike protein and mRNA.

If you understand the immune system at all, you should have expected / predicted these sorts of problems when they announced the mRNA vax. Anything that infects a cell and conscripts it to produce foreign proteins, marks that cell for death. Your immune system will eventually kill that cell to stop the foreign protein invasion. When this is in your sinuses or throat, it's irritating. When this is inside your intravenous system, it can be lethal.

You also can’t rule it out because no one knows what’s in the vaccines and safety trials were a joke.
