Idiopathic(90%)
Chromosomal Abnormalities
PATHOPHYSIOLOGY
Obstructions
Shunts & Regurgitations
CLINICAL
Murmurs
Cyanosis , clubbing , tachynoea
Fail to thrive
Complication: Pulm. HPT ,Cardiac Failure , Infective endo.
Poor feeding
R-L Shunts:EARLY CYANOSIS
Cause:
The T's
Transport of gr8 vessels
Persistent Trancus arteriousus
TOF:
RV outflow obstruct> Pulm artery Stenosis
Aorta Overrides
VSD
RVH
Tricuspid atresia>Regurg,RVH,Backwrd pressure
Blood bypasses pulm. circulation
L-R Shunts:LATE CYANOSIS
Excessive blood into pulm circulation
Pulm. HPT
Cause: The D's
Eisenmenger complex
OBSTRUCTION
Tubular Hypoplasisa
Aortic Valve Stenosis/artresia
Coarctation
