Congenital Pathology Flashcards
(33 cards)
congenital rubella causes what?
PDA
Gestational diabetes causes what?
transposition of vessels
hypoxema and cyanosis is caused by what?
right to left shunts
5 Right to Left Shunts
Tetralogy of Fallot, Trasponsition of great arteries, Truncus arterioles, tricuspid atresia, total anomalous pulmonary venous connection
what kind of embolism can right to left shunts cause?
paradoxical embolism - bc emboli bypasses lungs andcan go into systemic circulation i.e. brain
what three things can right to left shunts cause?
paradoxical embolism, long standing cyanosis, polycythemia
4 features of tetralogy of Fallot
Pulm Stenosis, Right V. hypetrophy, Overiding aorta, V-VSD
embryologic features of Teralogy of Fallot
anterosuperior displacement of the infundibular septum
boot shaped heart relates to
Tetralogy of Fallot
when does cyanosis develop
right sided pressure exceed left sided pressure
can there be postnatal life with transposition of the great arterues
no unless a shunt exists
what happens to the ventricles for transposition of the great arteries
right ventricular hypertrophy and left ventricular atrophy
what is persistent truncus arterioles associated with?
VSD
tricuspid atresia isa associated with?
ASD and a VSD
Mitral valve is larger than normal
hypoplasia of the right ventricle
what congenital anomaly has cyanosis from birth and high mortality within the first weeks of life?
tricuspid atresia
what is it called when pulmonary veins fail to directly join the left atrium
total anomalous pulmonary venous conection
volume and pressure hypertrophy, dilation of the right side of the heart and dilation of pulmonary trunk is due to what
total anomalous pulmonary venous connection
what condition can be asymptomatic until adulthood?
atrial septal defect
where is the location of ASD primum
adjacent to the AV valves (related to down syndrome)
Where is the location of ASD secundum
oval fossa near center of atrial septum
what is the most common congenital anomoly
VSD ( V in PROV)
where do most VSD’s occur?
membranous VSD
what has a machine like murmur?
patent ductus arteriosus
