Conflicting dr's diagnosis - help!

[VJsmom]

My DS is just over 8 weeks old. At his 6 week check up (at 7 wks) the gp picked up a heart murmur. Panicked, as any mother would be (new mom) I took him to the hospital that night. Two doctors, one an a&e cons and the other a paedeatric registrar both listed to DS's heart and both concurred no murmur.

Took DS to go yesterday due to chesty cough and saw the same GP who again said the murmur was still there. I said two a&e dr's didnt detect it but she stuck by her guns.
I do not know what to do or who to believe. DS is thriving well and is generally a happy hea;thy baby with no concerns from HV.
Surely if he did have a murmur this would have been picked up during scans and the monitoring during labour?
I have an app at hospital on 25th of this month to see dr as referred from gp but its a long time to wait.

My ds has a murmur that only shows up when he is unwell. Push for a scan to put your mind at rest.

No, prenatal scans don't show every defect so if there is a murmur it wouldn't necessarily have shown up.

A murmur simply describes a noise heard when listening to the heart. The most common murmur is a flow murmur which is entirely innocent and can come and go and is not assiciated with any heart problem. If your baby is thriving, then try not to worry and just wait for your appointment. It is entirely possible that your GP heard a murmur but there was nothing to hear in a&e - and that is v reassuring in itself. Any kind of significant murmur associated with a heart problem would always be audible.

To add to what mrsmellow said a flow murmur is literally just noisy blood flow. It was explained to us as the same way that if you take two houses with perfect working plumbing and run the kitchen tap in both, in one house it will make little noise and in the other it might be much noisier - the second house has the flow murmur: it's simply the liquid (blood) travelling through pipes (the heart) and making a bit of a racket while it does it.

Flow murmurs (also sometimes call 'innocent' murmurs) are really really hard to detect. For a number of reasons (none to do with heart/lung worries) DS was seen by many many doctors (A&E, paeds, GPs) including some very senior experienced ones in the first few years of his life. His heart was listened to countless times and no-one heard anything. Then we were doing our bit for the local hospital and DS (then aged 4) was pretending to be a patient for Final MB exams - the super-keen, desperate to do everything right students heard the murmur. What I'm trying to show is that they can be very very difficult to detect - when I casually mentioned that DS didn't have a murmur to the examiner the paeds registrar listened and couldn't really hear it, but the top GOSH doc who happened to be there did pick it up!

Going to A&E when there isn't any immediate concern for your baby's health won't really help; they are very unlikely to refer you onto any kind of cardio scan there and then. That doesn't stop it being worrying though as any parent hearing anything about 'heart' in the DC is going to worry. Why not go back to this GP explain that you're worried and can she give you more info, reassurance and is there anything else they can do to give you peace of mind.

Ds had a murmur picked up when brought to the GP on an unrelated matter at 4 weeks.
By the time we'd got a consultants appointment 3 weeks later, it had pretty much cleared. It's never been heard since. Consultant was happy to decid it had cleared-I believe most do without intervention.

A murmur can be very much just one of those things that is there and doesn't effect the dc.
My dsis picked up that she had a slight murmur when doing medical training when she was hooked up to a machine... never spotted or bothered her before or after.
A friend's ds has a murmur that can easily be heard. He has a check up every year and it's still there-doesn't stop him competing at a regional level in athletics and hockey.

DS has a mummer & a small VDS (hole in his heart). He had two holes but one had closed by 12 weeks. The other just needs monitoring.

They most important thing is if he has any other symptoms. Does he get sweaty and tired when feeding? Is his weight gain ok? Does he ever get cyanosed and go a bit blue?

DS is 15 months now and running around completely fine. The hole is still there but asymptomatic.

thanks for all the replies, had to take ds to out of hours on Thursday due to high temp which calpol didn't really touch and the gp there also said he had one but it was an innocent one and not to worry so now that's two saying he has but two saying not and one saying no murmurs was a child doc? His weight gain is good and is generally a healthy happy baby
