Hi, Rose. I don't have a lot of answers, but I can tell you what I know. I too have a heart murmur, which is officially called "mitral valve prolapse." My cardiologist told me that the condition is quite common and is usually benign, although in some cases can be serious. I have periodic chest pain, but nothing severe. I also have periodic irregular heartbeat, which my cardiologist knows about. He had me wear a portable heart monitor for 24 hours on two different occasions so he could see the pattern of my irregular beats. I assume your boyfriend is seeing a cardiologist. If not, I would recommend it. Also, when he has dental work done, he should take an antibiotic beforehand. I'm sure he already knows about that. Good luck! --Russ
