Paeds Flashcards
Causes of acyanotic congenital heart disease
ASD VSD PDA Coarctation of aorta Isolated valve lesion Aortopulmonary window
What is reversal of a acyanotic L to R shunt to a cyanotic R to L shunt called?
Eisenmenger’s syndrome
Causes of cyanotic congenital heart disease
Tetrology of fallot's Transposition of great arteries Tricuspid or pulmonary atresia Hypoplastic left heart Univentricular heart
What do cyanotic conditions such as tricuspid atresia and transposition of the great arteries require to be viable?
A shunt, either an ASD, VSD or PDA
S+S of VSD
Mild symptoms
Harsh blowing pansystolic murmur +/- thrill (widespread but especially left sternal edge)
ECG and CXR findings in VSD
ECG - normal progressing to LVH
CXR - pulmonary engorgement
Prognosis and management of VSD
20% close by 9 months
Large may need surgery
S+S of ASD
Usually asymptomatic
Widely split S2 and systolic pulmonary flow murmur (left sternal edge 2nd ics)
Signs of decompensation in a child with congenital heart disease?
Heart failure (sob, hepatomegally, jvp, tachycardia)
Acidosis
Failure to thrive
Poor feeding
Standard advice to patients with congenital heart disease
Avoid competitive sport and contact (relevant to most)
Ensure good dental hygiene
Avoid tattoos and piercings
ECG and CXR findings of ASD
RVH +/- RBBB
Cardiomegally / globular heart
S+S of PDA
Failure to thrive Pneumonia CCF Thrill Systolic pulmonary murmur or continuous hum
ECG findings of PDA
LVH
Prognosis and management of PDA
Usually spontaniously closes in a couple of weeks
If distress or compromise - treat CHF, IV indomethacin or ibuprofen to close
Catheter occlusion or surgical ligation
What must be done before closing a PDA?
Ensure no other cardiac defects - eg pulmonary atresia, which may rely on the PDA for function
S+S of coarctation of the aorta
Decreased femoral pulses
Raised arm BP
Systolic murmur left upper sternum
Heart failure
When do symptoms of coarctation of the aorta tend to occur?
Day 2-10 post birth as the DA closes
Components of tetralogy of fallot?
RVH
Overriding aorta
Right ventricular outflow tract obstruction (pulmonary stenosis)
VSD
S+S of tetralogy of fallot
Cyanosis
Dysponea
Faints
Squatting (increases pvr so decreases r-l shunt)
Treatment of suspected fallots tetrad
O2 Knees to chest Morphine to sedate Beta blockers Surgical repair
What is ebsteins anomaly
Effect?
Downward displacement of tricuspid valve
Atralises right ventricle causing RHF
A patient with duct dependent cyanotic heart disease needs their duct kept open! How is this done?
Administration of alprostadil
What is an example of a benign murmur in a kid? Other terms? What are the features?
Stills murmur.
Flow murmur. Functional murmur.
Lack of worrying signs (heaves, thrills, chf, clubbing, cyanosis, arrhythmia, failure to thrive), grade 1/2 only, normal variable splitting of S2, vibratory or musical, lower left sternum, decreased on standing or arching back
What congenital defects would cause fixed splitting of S2?
ASD
