I was diagnosed with a heart murmur at age two, that got steadily worse over the years until I had to have open heart surgery at age nine. I had a subaortic stenosis that had to be cleared out. If anyone wants basic details on the TWO methods they used to clear out the stenosis, you're more than welcome to ask.
Bottom line, I will always have a residual murmur and will never be able to run further than a quarter mile. No enlisting in the armed forces, no strenuous sports, so on and so forth. So yes, heart murmurs can be quite serious. However, as we've all noticed already, thanks to Hebe, they're OFTEN nothing at all.
