By the end of the session you should; Recognise common heart murmurs present in
childhood
Be able to list the risk factors for cardiac disease in childhood
Be able to define innocent murmurs and explain to parents
Be able to answer exam-based questions
Learning Outcomes
A 5 year old girl attends A+E with a 2 day history of watery eyes, cough and runny nose
She is also pulling at her left ear intermittently and is off her food and drinks
She has no relevant medical history, though there is a family history of epilepsy
Case 1
Observations: HR 124, RR 28, Sats 97%, T 37.9
On examination:Red, watery eyes and coryzal, inflamed left TM HS I + II + systolic murmurChest: good AE with transmitted sounds and mild wheeze bilaterallyAbdo: SNT, no masses or organomegaly
What do you think about the observations?What else would you want to ask/examine?
Case 1
Murmur loudest at the upper left sternal edge, no radiation, thrills or heaves
Brachial and femoral pulses present, with good volume
No other stigmata of cardiac disease
What are your differential diagnoses?Do you want any further investigations or F/U?
Case 1
Innocent murmurs are common in childhood
They are;SystolicSoft (or musical)Localised with no radiationAlter with changes in position and respiration
As there is no underlying cardiac abnormality there are no other associated symptoms
Innocent Murmurs
Flow murmur: HR and blood flow within the heart increase in response to
increased oxygen demand Turbulent blood flow results in an audible murmur Loudest at the left sternal edge
Venous hum: Around 20% of cardiac output flows to the brain, which in
turn drains into the internal jugular veins The flow of blood results in ‘vibration’ of the vessel walls,
resulting in an audible ‘hum’ Loudest beneath the clavicle, and obliterated on lying flat
Innocent Murmurs
No investigation is needed in a well child with otherwise normal examination/observations
Follow up should be arranged in 6-8 weeks when the child is well to review the murmur
If still present reassure parents
Echo if any doubt regarding murmur/red flags
Innocent Murmurs
A 6 month old attends paediatric outpatients with failure to thrive and recurrent LRTIs
He was born on the 50th centile, and now sits below the 2nd
His intake is adequate for his age and he is otherwise developing normally
Case 2
On examination: Bright, good colour and tone, mild tachypnoea
Small, but no evidence of dysmorphism
HS I + II + continuous murmur loudest in the infraclavicular area
Bounding brachial and femoral pulses
Chest: good air entry with no added sounds
Abdo: SNT, 2cm liver edge palpable
Case 2
In utero the ductus allows diversion of blood away from the lungs (pulmonary artery to aorta)
It usually closes on day 1-2 of life, and disappears by week 3
Risk factors:Female sex Downs syndromeCongenital rubella Maternal valproate exposurePrematurity
Patent Ductus Arteriosus
Small PDAs are usually asymptomatic
Large PDAs present with failure to thrive and recurrent LRTIs in childhood
Continuous ‘machinery murmur’ in the infraclavicular area or upper left sternal edge
Associated systolic thrill and bounding pulses
Echo confirms diagnosis and shunt size
Patent Ductus Arteriosus
Symptomatic patients: Preterm: ibuprofen or indometacin
Diuretics for heart failure
Surgical ligation
Asymptomatic patients: Regular echo review and catheter closure if still
patent at 1 year
Patent Ductus Arteriosus
A 2 year old girl is referred to paediatric outpatients with a heart murmur
It was found on routine examination by her GP
She is otherwise well and developing normally
Mum’s only concerns is that she is much shorter than her nursery friends and siblings
Case 3
On examination:Short, with low set earsPink and well perfused, CRT <2 secsHS I + II + systolic murmur loudest in L infraclavicular
area and radiating into the backFemoral pulses are present, but weak
Is there anything else you want to check?What is the most likely diagnosis?
Case 3
Narrowing of the aortic arch
Usually distal to left subclavian artery, near the ductus arteriosus
Results in proximal hypertension, ventricular hypertrophy and eventually heart failure
Risk factors:Males Positive family historyTurner’s syndrome
Aortic Coarctation
Investigation includes:CXR ECG MRIEcho U+E +/- cardiac catheter
Management depends on presentation:Critical stenosis in neonates – prostaglandinHeart failure – diureticsHypertension – anti-hypertensives
Definitive management is surgical
Aortic Coarctation
A 6 week old boy is referred with poor feeding, failure to thrive and increased WOB
Mum did not attend antenatal clinics, but reports no pregnancy problems other than her ‘age’ (42)
He was born by normal vaginal delivery, did not require resuscitation and has been well since
There is no family history of note
Case 4
On examination:Pink and active, mild hypotonia and low set earsCRT <2 secs, RR 62, sats 95%, pulse normalHS I + II + pansystolic murmur at lower LSELeft parasternal heave, no thrillsChest clear, abdo SNT
What are your differential diagnoses?
Case 4
Most common form of congenital heart disease
One or more defects in the interventricular septum
Most VSDs occur in the perimembranous area
Risk factors;The trisomies (13/18/21) Turners syndrome (45XO)Maternal diabetes Fetal alcohol syndrome
VSD
Presentation depends on; Size of VSD Right/left ventricular pressures Size of shunt across defect
Small: asymptomatic, murmur on examination (pansystolic, loudest at LSE)
Moderate: SOB on feeding from 5-6 weeks of life, increased WOB and poor weight gain
Large: as above, but may lead to irreversible pulmonary hypertension and cyanosis
VSD
Diagnosis confirmed on echo
Many small VSDs close spontaneously <2yrs
Management if symptomatic; Medical: diuretics and high-calorie feeds Surgical: open-heart surgery or catheter closure
VSD
Congenital (acyanotic); ASD AVSD (Downs syndrome)
Congenital (cyanotic); Tetralogy of Fallot Transposition of the Great Arteries
Acquired; Coronary artery aneuryms (Kawasaki disease) Carditis/mitral valve disease (rheumatic fever)
Other Conditions
Murmur in an asymptomatic child is most likely innocent
Innocent murmurs do not need investigating, and family should be reassured
Congenital heart disease may present with cyanosis, heart failure, feeding issues and respiratory distress
Echo is the key investigation, and acute management should follow an ABCDE approach
