Hi I was diagnosed with heart disease and need triple bypass. Most worrying thing is that due to varicose veins in both legs I have been referred to professor al attar at Goode jubilee Glasgow as he specialises on bypass surgery not using leg veins. As I understand it he will rewire mammary veins. My worry is that during visit in clinic he said that means there is no back up plan!! Frightened the wits of me. I expressed my fears to cardiac nurse who said not to worry they will get a vein from somewhere else. Anyone been in this situation? Would love to hear positive outcomes.
