Hello Doctor, As I am trying to evaluate different options for my Dad, doctors told me to go for CABG instead of EECP, so I researched a bit more on CABG and found MICS. So in my dad's case who has 90% block in RA and 90% and 70% block in LAD with a smaller block of 50-60% in the area near to arota in LAD. So in this case is MICS possible as he is not having any other issues with good heart function.
