Pedia Pedia Presentation Transcript

  • Congenital Heart Defects Defects with Increased Pulmonary Blood Flow
  • Atrial Septal Defect
    • An abnormal connection between the R and L atria and is illustrated in the diagram.
    • Clinical Manifestations
    • - generally asymptomatic
    • - with soft systolic murmur
    • - more classically a widely split S2 unaffected by respiratory pattern.
    • Diagnostics
    • - presence of murmur
    • - CXR – cardiomegaly
    • - ECG - demonstrates size of defect.
    • - cardiac death is not routinely indicated for dx of a n isolated ASD.
    • Treatment
    • - preoperative interaction
    • - Diuretics
    • - surgical repair is performed in the preschool age.
    • - sternotomy
  • Ventricular Septal Defect
    • Abnormal connection bet R. and L Ventricles.
    • Clinical Manifestations
    • - asymptomatic
    • - large defect – CHF
    • - tachypneic, diaphoretic, fatigues easily, underweight for age
    • - tires before feeding is completed.
    • Diagnostics
    • - loud holosystic murmur
    • - Normal CXR
    • - large defects (cardiomegaly, increased in pulmonary blood flow)
    • - ECG (shows size of defect)
  • Patent Ductus Arteriosus
    • Direct connection between the main pulmonary artery and the aorta.
    • Term newborn – the ductus closes within 12 hours and should be closed by 2-3 weeks.
    • s/s
    • - if small : asymptomatic
    • - if large : CHF
  • Atrioventricular Septal Defects
    • Asso. With septal defects in the atrium and ventricle as well as involvement of the AV Valves.
    • s/s:
    • - s/s of CHF
    • - with murmur
    • - virtually all are asymptomatic
  • Truncus Arteriosus
    • Single arterial trunk arises from the heart.
    • s/s:
    • - cyanosis
    • - w/ s/s of CHF
    • - with loud continuous murmur
    • - symptoms always develop in the 1 st month of life.
  • Defects with decrease Pulmonary Blood Flow
    • Pulmonary Stenosis
    • - refers to narrowing of the pulmonary valve and obstruction to blood flow from the R ventricle to the lungs.
    • - s/s :
    • - mild to moderate – asymptomatic with mumur
    • - normal growth
    • - dyspneas, cyanosis
  • Tetralogy of Fallot
    • Made up of VSD, PS and R Ventricular hypertrophy, overriding aorta
    • s/s:
    • - TET spells
    • - cyanosis
    • - hyperpnea
  • Transposition of the Great Aorta
    • The aorta and the pulmonary artery is transposed or reversed.
  • Tricuspid Atresia
    • Characterized by absence of or complete closure of the tricuspid valve and therefore no connection bet the RA and the RV.
    • Includes ASD, VSD, and varying degrees of RV hypoplasia.
    • Maybe due to underdeveloped / incomplete development.
