Paediatric Cardiology - Liam Flashcards
Innocent murmurs
Short, systolic, symptonless
Murmur caused by mitral regurgitation
Pan-systolic
Murmur caused by tricuspid regurgitation
Pan systolic
Murmur caused by ventricular septal defect
Pan systolic
Murmur caused by aortic stenosis
Ejection systolic
Murmur caused by pulmonary stenosis
Ejection systolic
Murmur caused by hypertrophic obstructive cardiomyopathy
Murmur caused by atrial septal defect
Mid-systolic, crescendo-decrescendo murmur with fixed split second heart sound
Murmur caused by patent ductus arteriosus
May not cause one
Tertralogy of fallot murmur
Is due to the pulmonary stenosis, so ejection systolic
What is cyanotic heart disease
Cyanosis when deoxygenated blood enters systemic circulation (bypass pulmonary with right to left shunt)
4 heart defects that cause cyanotic heart disease
Ventricular septal defect
Atrial septal defect
Patent ductus arteriosus
Transposition of the great arteries
(first 3 usually not unless pressure in right side of heart is far higher than normal)
Patent ductus arteriosus
- management
- Monitored with EEG until 1 year old
- Surgical closure if doesnt close spontaneously
Atrial septal defect:
- management
- Transvenous catheter closure or open heart surgery
- Anticoagulants (aspirin, warfarin, NOACs) to reduce risk of stroke in adults
Eisenmenger syndrome:
- pathology
- Ventral septal defect causes pulmonary hypertension
- Increased pressure in right side heart allows shunt from right to left
- Patient becomes cyanotic - this is Eisenmenger syndrome
