Awww Sounds like he has a real struggle in the beginning.......that is the problem with heart surgery,.,....the surgeon explained that to me....he said the heart surgery was good for the heart, unfortunately is wasn't good for the other organs.......anything can happen that's for sure......well according to the catherization and echo cardiograms and my heart ejection fraction...I have no muscle damage......He thinks I should do fine......but with any major surgery, anything can happen.......it's all in ***'s hands and a very talented team of Drs. Thanks for the information.......I wish you and your hubby the best::-)....Take Care Lola:-)
