An angiogram is the safest test that will give definitive results. Precede with confidence. I think being crushed by a piano when walking a city street is a bigger risk.
Agree. I've had three and open heart surgery.. and have had no problems induced by the procedures.. in fact my mitral valve has worked well for 8 years at this point.
Don't have a number on risk or severity, but simple recovery will have to take place, but best I can recall other than having to be driven home and not drive for the rest of the day, I had no after/side effects.
