Magnetic exercise bike and prosthetic heart valve?

Question

my friend's mom has a prosthetic(artificial) mechanical heart valve (St jude). is it safe for her to exercise on MAGNETIC resistance stationary exercise bike? i mean will there be any adverse interaction between the metallic heart valve and the bike's magnet?

Answer 1

I do all the time. The mag effect is very small. For her piece of mind all she needs to do is phone her cardiologist.
