Is Heart Muscle Tissue Found in All Five Cases?

In lancian's case, a host reportedly turned into a piece of solid tissue. Waud they find when they studied that, they found out it was made of heart muscle. And here's where things get strange er, because it looks like heart muscle tissue was found in the other four cases as well. Even the ones that they tried to dissolve a dirty host in water, and it grew what looked like a blood clot. It wasn't a blood clot, but contained heart muscle tissue. This is thus really strange from the perspective of hoaxing.
