Congenital heart issues Flashcards
etiology of coarctation of the aorta
congenital?
acquired?
congential -Turner’s syndrome
acquired -(Rare)- Takayasu arteritis
Clinical features of coarctation of the aorta
Upper body- well developed and HTN with headaches and epistaxis. Hear a left interscapular systolic continuous murmur
Lower body - underdeveloped and claudication Brachial femoral pulse delay
Upper and lower body BP differs
Diagnosis of coarctation of the aorta
ECG (LVH) CXR - inferior notching of hte 3rd to 8th ribs 3” sign due to aortic indentation TTE
Treatment of coarctation of the aorta
balloon angioplasty and stent placement or surgery
most common associated defect with Coarctation of aorta is:
bicuspid aortic valve (seen in 40% of cases)
Large ASD can cause a left to right shunt and this can result in these findings on EKG
QRS can be prolonged wit ha rSr’ or rsR’ configuration which can cause a incomplete or complete RBBB on EKG. Can also see 1st degree AV block R axis deviation or P wave changes suggestive of RAH
Ebstein’s anomaly can also have
WPW accessory pathway in 20% of the time.
atrial septal defect (ASD) and moderate to large left to right shunt have increased flow through (which valve)
through the pulmonic valve and creates a mid systolic ejection murmur due to a large left to right shunting.
symptoms vary depending on severity of shunt and often occur by age 40.
Tx is surgical repair.
Initial symptoms are: fatigue, afib or flutter, stroke due to paradoxical embolism or pulmonary HTN. cyanosis only seen with theres’ another congenital malformation like pulmonary stenosis.
what is characteristic of ASD murmur?
wide and fixed split second heart sound.
continuous murmur in left infraclavicular region
patent ductus arteriosus
moderate sized PDA can present with
dyspnea and exercise intolerance due to LV failure and wide pulse pressure
see bounding pulses and laterally displaced apical impulse
large PDA can have
left to right shunting that leads to left ventricular LV volume overload and high output heart failure in infancy and early childhood.
If untreated, can progress to pulmonary HTN and Eisenmenger syndrome (Right to left shunting)
pts who have unrepaired PDA are at greater risk for
infective endarteritis or PDA related endocarditis esp if there’s associated pulmonary HTN
see vegetations affecting the pulmonary end of PDA and leading to septic emboli
indication for closure of PDA
history of infective endarteritis and infective endocarditis.
congenital coarctation of aorta increases risk for
aortic dissection and intracranial aneurysm
see higher upper body HTN and decreased blood flow to extremities can have headaches and epistaxis
