Dad's cardiac catheterization test is underway right now.  Let's hope everything looks good.

He arrived at the hospital at 8:30am this morning and they started the test at about 11:45 am.  The test should last approx 1 1/2 hours. 

If they discover he needs a stent, they will do that today and he'll stay overnight.

If they discover he needs a valve replacement, they will likely schedule that for another date.
