hello, be careful ..this sounds like my story..always got antibiotics before going to dentist, had 2 x rheumatic fever when a child, was on my history etc..never been to a heart specialist till my new GP wanted to know why I had asked for the anibiotics..told him I always had them before going to dentist as i had a heart murmur..same as you mum told me etc..within a very short time..weeks i had had opn heart surgery and aortic valve replaced,,so very lucky to be alive my cardiac surgeon said....please get ti checked properly, ask for a referral to a cardologist for your own peace of mind.
Systolic or diastolic murmur? Physiological pulmonary regurgitation is generally not audible as is trivial/mild mitral regurgitation in the presence of normal valves. Physiologic regurgitation of any of the valves is common in normal people and in itself is not a diagnosis. Perhaps this was marked on the report but by no means is the definite source of the murmur which is the case for many innocent murmurs.
