Hi Amy,
Yes, I have had this procedure and it saved my life. Everything thing will be ok. It sounds more serious that it actually is. They enter under the breast bone instead of opening up full chest again.
I felt wonderful immediately following surgery. The tamponade had me in severe CHF. My oxygen level was extreamly low. Was very pale, and actually a bit blue in color. Was transferred out of CICU the following AM.
My window was an emergency as the INR had traveled upward to 14. No mistake in that number. I really should not have recovered they say. This was due to the fact that the high INR caused alot of internal bleeding. I was fully transfused with fresh frozen plazma. Fortunately, this is not the case with your husband.
They think that my Coumadin llevel caused the tamponade. I was being monitored closely, but not close enough as when I was at a 4.0. They left my dosage alone and did not decrease.Fresh surgical site and a higher than normal INR probably attributed to my Tamponade.
If I can help any further, just ask.
God bless.
