Default No Left heart manifestations on Carcinoid Syndrome

Just found out this...which I found really interesting!

So Serotonin is normally metabolized in the Liver by MAO
When metastasize to liver begins to be dump into Hepatic Vein and goes to Right Heart
Once in Right heart goes to Lung ...where we have also it gets metabolized and it is not able to go to Left Heart (less commonly)

The lung actually protects the Let Heart by inactivating Serotonin

So when Carcinoid Syndrome think always Right Heart affectation...
