Not really a tech question, but thought someone out there has been through it and could offer advice. Currently hold a Pro-Sportsman NHRA license, and have been diagnosed with a moderate to severe heart murmur, technically it is called "Mitral Valve Prolapse". Possible heart surgery required. Is this the end of my driving days? or after surgery can you get a clean bill of health? How tough is NHRA on this? Thanks for any advice or sharing any experiences you might have had.
