Tetralogy of Fallot from http://www.tmc.edu/thi/tetrolog.html:
 
Tetralogy of Fallot is made up of 4 heart defects:
 
* A hole in the wall between the lower chambers (the ventricles), which
lets oxygen-poor blood mix with oxygen-rich blood.  This is called a
ventricular septal defect.
 
* A narrowed outlet to the pulmonary artery, usually along with an
abnormal pulmonary valve.  This can block blood flow from the lower-right
chamber (the right ventricle) into the lungs.
 
* An aorta that straddles the wall (septum) between the lower chambers
(the ventricles).  This lets oxygen-poor blood flow into the aorta (the
main blood supplier to the body).
 
* Thickened and enlarged heart muscle tissue in the lower-right chamber
(the right ventricle).
 
So the blood pumped winds up being oxygen depleted.
 
So, this is NOT what I was wondering if it may be: not, not, not.
It's interesting; when i was a teen a neighbor boy had this but I
never knew the formal name.

it appears that Dr. Tony Creazzo is still at the same med school.

I've run out of time to keep looking at things right now...
