well when they put in the CATH, then they will know for sure what needs to be done. i got to the cath lab, was told i might need a stint. wellllllllll they found a "widowmaker" blockage and told me i was on my way to the O.R. while they was inside of me fixing that one........they found a 2nd blockage, the left anterior dissenting artery. so they by-passed it also. just pray its nothing more then a stint.
