A patent foramen ovale also creats another problem besides incomplete
blood transport (with soluable nitrogen) back to the lungs. The other 
problem is that it forms a low pressure area in the heart (cavitation) 
that could hasten nitrogen coming out of solution in the immediate area.
Not only could a bubble form in the heart (causing problems on ascent), 
but could also lead to an air embolism along the lines of an Arterial 
Gas Embolism (spontaneous gas forms in blood stream due to too rapid
of an ascent).

And we thought diving was fun.

Any comments on this, do I have it right?
