CV Flashcards
2 main questions when assessing congenital heart disease?
compensated??
cyanosis?
what direction of shunt causes cyanosis?
Right to Left
CF of decompensation in child
poor feeding, SOB, hepatomegaly, engorged neck veins, tachycard, weak pulse +/- acidosis
Cauuuuses of Acyanotic and Cyanotic
Acyanotic (Left to Right shunt)
ASD,VSD, coarctation aorta, isolated valve lesion, patent ductus
Cyanotic (R to L)
Fallots tetrad, transpoosition great arteries, tricuspid/pulm atresia, TA PVR, hypoplastic left heart syndrome
Common investigations of congenital heart disease
ECHO, c xray, cardiac catheter
ECG, SpO2
FBC
Typical chromosomal disease congenital heart dis
DOWNS - AVSD/VSD/ASD/Tertralogy of Fallot
TURNERS - AS/Coarctation aorta/ bicuspid aortic valve
DiGeorge - conotruncal abnorm
VSD - CF/o/e / I / T
CF - mild (80%) with harsh/loud pansystolic blowing murmur +/- thrill leading to cardiac failure
I - ECG (norm at biirth, later in life = L/RVH) cxray - pulm engorgment
T - 20% will close spontaneously within 9 months but can be treated pharmacologically / Larger defects will require surgery
ASD - CF/ I
No CF as such, but widely ssplit, fixed S2 + systolic murmur heard.
I - cxray = cardiomegaly // ECG - RVH +/- incomplete RBBB
Patent Ductus - CF / II / T
CF - failure to thrive,,,,,,,,, bounding fem pulse, pnneumonias, CCF, SBE, collapsing, loud S2, systolic pulm murmur
I - cxray - increased vascular markings, big aorta / ECG - LVH
T - Dexamethasone (duing pre-term labour) +/- indometacin or ibuprofen
Coarctation of Aorta - CF / I / T
CF - often SHOCKED! diff to feel fem pulses, CCF, unequal BP across limbs (up in arms, low in legs), systolicc murmur, absent foot pulses.
I - cxray - rib notching + cardiomegaly / EECG - LVH
T - surgery or stenting/balloon
Transposition of great arteries - CF / I / T
CF - cyanosis, CCF, +/- systolic murmur
I - cxray - egg shaped heart / ECG - RVH
T - balloon atrial septostomy
Causes of Heart Failure in NeoNate/ infant/ child
NeoNate - PDA / hypoplastic left heart syn / coarctation of aortta
Infant - VSD / cardiomyopathy
Child - Cardiomyopathy / failing congentical heart disease
Non cardiac causes of heart failure?
- Stress (fever/ hypoxia / infection)
- Anaemia
- Fluid Overload
Tetralogy of Fallots - ?/ CF/ I
? - VSD + RVH + Aortic overriding of VSD + Pulm Stenosis (RV outflow obs)
CF - cyanosis as ductus closes, SOB, faints, clubbing, thrills, harsh systolic murmur.
(child copes with symp by squatting)
I - FBC (Hb up) , cxray (boot shaped heart + RVH)
Infective Endocarditis - C / CF / I / T
C - ctrep viridans,
CF - fever, splinter haem, spleomeg, haematuria, weight down, malaise, clubbing??
I - blood cultures x3 (diferent sites)
ECHO - any vegetation of valve
T - IV abx’s for at least 6 weeks (ben pen and gent until cultures back)
