So my little baby guy has Pulmonary Hypertension.
(he fell asleep while standing up on the car ride home from the desert...too cute huh?)
This explains why his heart was enlarged and why he was having trouble breathing. The good news is it can be controlled with a pill everyday. And the funny part is they prescribed him Cialis (haha yes you've seen the commercials). I guess it's original reason for being made was to control pulmonary hypertension. Go figure :)
