So, here is a little info from a guy who has worked in cardiac surgery since 1974,,operating room nurse.
The golden connection that has over time proven to almost “plug up proof” is the internal mammary artery to the big artery supplying the left ventricle. There is an internal mammary artery that runs on either side of your sternum. The left is free’d up but left connected at its origin so it has its natural blood flow . Then, the far end is clipped, cut , prepared and used to revascularize that big artery feeding the left ventricle. For whatever reason, if performed technically correct, that connection will outlive you. For other blockages , a vein from your leg will be harvested with an endoscope( much less pain than in old days when your leg would’ve been filleted for the vein harvest) then connected past the blockages on those other artery’s , then the other end is connected to your aorta where blood is pumped through the vein, past the blockages, to revascularize the previously “starving areas”. It’s a very cool procedure and allotta advances have been made to fine tune it over the years.
Since I don’t see pts once they leave the O.R. I can’t make suggestions concerning recovery time etc. everything posted sounds like good advice. I know how well you have cared for yourself helps make the surgeon’s job easier, and we see a high number of pt’s Who just have crappy artery’s , you can bypass the major blockage, but the whole artery may full of small plaque’s it’s entire length. Or , the artery will be very small and not carry a large amount of blood flow. Just take it easy and listen to your medical staff and folks who have had the procedure previously, best of luck
