I'm going to play devil's advocate here ; ) I had the angiogram done 2 days before my surgery. I was really nervous about it, because my kidneys are slightly impaired and the dye they use can sometimes harm the kidneys, esp those like me with prior kidney disease. I was told the procedure was routine prior to heart surgery for the sole purpose of seeing if bypass would be needed during surgery. A doctor other than my surgeon performed the angiogram.
I predicted they would find no blockages. I'm in shape, work out, have been taking daily fish oil supplements for over ten years. And, I was right, my veins and arteries were in good shape. (Hard to beat dat fish oil.) While the procedure wasn't bad to go through -at least as bad as I'd imagined - I still wonder if I had gotten a less experienced surgeon or was just unlucky and ended up with kidney damage because of it, how I would be feeling today. My surgeon was top notch and used only 40% of the dye normally used. I guess it's a trade off, but they usually don't let you - the patient - make the decision on weather or not to do this. So I commend your doctor for his unorthodox stance - he's weighing the risks of the procedure vs. the benefits. And, if I need another open heart in 10 or 15 years, they will be hard pressed to have me go through the angiogram again if I'm still exercising and eating right. Of course, they may be putting the valve in using a Cath by then ; ) and I would have to have it anyway.
