When I was born I had this rich tapestry of complications;

basically, my great arteries went the wrong way (meaning no oxygenated blood flow throughout my body), the ventricles in my heart had a massive hole in them, and my pulmonary valve was stiff as shit so it wouldn't open and close properly.
because of the surgery done to fix that when I was around 2-years old, my pulmonary valve was punctured, so it wasn't appropriately regulating blood flow through the pulmonary artery. Not a huge issue, but it eventually caught up with me as that excess blood began to leak out of the artery, so I had surgery to correct that back in 2012.
