Earlier quoted context omitted.
In many cases, it doesn't cause problems. In the absence of congenital heart defects, individuals with situs inversus are phenotypically normal, and can live normal healthy lives, without any complications related to their medical condition. There is a 5–10% prevalence of congenital heart disease in individuals with situs inversus totalis https://en.m.wikipedia.org/wiki/Situs_inversus
I understand this. My question is what is the mechanism that causes the 5-10% prevalence? Was something not mirrored? I only ask because it wasn't explained on wikipedia.
From my read, yes, sometimes not everything is mirrored. But, also, a problem with the cilia can be a cause of the organ reversal. This will cause additional health problems.
Just trying to be helpful. Hope that answers your question.
