I, also, have a heart murmur after getting a new mechanical aortic valve. Cardio says he can barely hear it and, at this point, he doesn't want to even do any tests because they aren't really valid so soon after surgery. He wants to wait and let the valve settle in. And since I feel good and have no complaints, I am happy with this. My cardio is the Buddha of cardiology....he is so soothing and just kicks back in his chair and listens to you, then works his calmology and soothes all your fears and questions.
My heart also skips beats on a regular basis but on an irregular rhythm. But I am not aware of it at all unless I'm sitting there taking my pulse at my wrist or neck. He didn't seem concerned about this either but did say to call him if I became aware of the skipped beats during my regular activities. I have no A-fib or anything else so will go with his judgement. At this point the only meds I take are the Coumadin for my mechanical valve and Fosomax and calcium for my bones. Feel really fortunate about that.
