The Woman With Reversed Organs:

Bentley had a rare condition called situs inversus, which is almost always fatal. The condition places the liver, stomach, and other organs in the abdomen in the wrong place, which can be dangerous when the blood vessels don’t reach the organs properly. However, Walker explains Bentley was lucky because her heart was (literally) in the right place, so her condition was much less dangerous. Medical literature describes two other people with the same condition, with similarly positioned hearts, and they both lived normal lifespans, into their 70’s.
