Q

What questions are important to ask in a paediatric patient you suspect of having a congenital heart condition?

A

1 - How is their feeding, weight and development?

2 - Signs of cyanosis

3 - Rapid breathing

4 - SOB

5 - Poor exercise tolerance

6 - Chest pain

20
Q

What features can be observed on examination of a child with a congenital heart defect?

A
  • Reduced weight and height
  • Cyanosis
  • Finger clubbing
  • Radio-femoral delay
  • Murmurs
21
Q

What investigations can be performed to help diagnose a congenital heart defect?

A

1 - O2 sats

2 - ECG

3 - Echocardiogram

4 - Exercise testing

5 - Angiogram

22
Q

What are the principles of treatment of paediatric heart defects?

A

1) Fix it
2) If it cant be fixed, use ballon valvo-plasty, shunt, prostaglandins etc.
3) Replace the defective structure

23
Q

What are the common harmless murmurs?

A

1 - Still’s murmur

2 - Pulmonary outflow murmur

3 - Carotid bruits

4 - Venous Hum

24
Q

What are the 3 main types of VSD’s?

A

1 - Subaortic

2 - Perimembranous

3 - Muscular

25
Q

What type of shunt occurs as a result of VSD’s?

A

Left to right shunt

26
Q

What else are VSD’s commonly known and why do they have this alternative name?

A

Acyanotic heart defect

Acyanotic because the blood is not by-passing the lungs as happens in right to left shunts

27
Q

How does a VSD present clinically?

A

1 - Pansystolic murmur on LLSE

2 - Tachycardia (sign of heart failure in children)

3 - Tachypnoea (sign of heart failure in children)

4 - Hepatomegaly (sign of heart failure in children)

28
Q

What are the long term complications of VSD?

A

1 - Ventricular hypertrophy

2 - Pulmonary hypertension

29
Q

What is eisenmenger syndrome?

A

The reversal of a L-R shunt into a R-L shunt resulting in cyanosis

30
Q

How can VSD’s be closed?

A

Amplatzer device

Patch closure

31
Q

What are the features of ASD’s?

A
  • Few clinical signs in early childhood
  • Often closes spontaneously
  • Sometimes detected in adulthood with AF
32
Q

With which Trisomy ar Atrioventricular-septal defects associated?

A

Trisomy 21

33
Q

What are the clinical features of pulmonary stenosis in children?

A

Ejection systolic murmur upper left sternal border with radiation to back

34
Q

What are the symptoms of a child with aortic stenosis?

A

Exercise intolerance

Exertional chest pain

Syncope

35
Q

What are features of an aortic stenosis murmur in children?

A

Ejection systolic murmur

Upper right sternal border

Radiates to carotids

36
Q

Which blood vessel supplies oxygenatedblood to the fetal heart?

A

Umbilical vein

37
Q

What changes occur in fetal circulation at birth?

A

1 - Pulmonary blood increases

2 - Systemic vascular resistance increases

3 - Ductus arteriosus closes

4 - Foramen Ovale closes

5 - Ductus Venosus closes

38
Q

In which group of infants is patent ductus arteriosus most common?

A

Pre-term infants

39
Q

What treatments can be given to help close a patent ductus arteriosus?

A

1 - Prostaglandin inhibitors

2 - Diuretics

40
Q

What is co-arctation of the aorta?

A

Kink in descending aorta wall

Kink is close to ductus arteriosus

41
Q

What are some clinical features of co-arctation of the aorta?

A

Radio-femoral delay

42
Q

How can co-arctation of the aorta be imaged?

A

Echocardiogram

MRI

43
Q

How are co-arctations of the aorta managed?

A

1 - Re-open PDA with prostaglandins

2 - Resect the coarcted part and anastamosis

3 - Ballon aortoplasty

44

What happens in transposition of the great arteries?

A

Aorta connected to right ventricle

Pulmonary veins connected to left ventricle

No oxygenated blood being moved around body

45

A

1 - Malposition of aorta

2 - Pulmonary stenosis
