Is there a vet teaching hospital, or a specialist (cardiologist/pulmonary?) that you can take her to? I don't know anything about veterniary care in Costa Rica, but here there are vet teaching hospitals that can sometimes solve problems that local vets are stumped by.
I hope someone from the forum with some knowledge of this condition can comment, I'm sorry I can't help more.
Please keep us posted on how she's doing- my heart goes out to you-
