Echo 530

  1. Define: Morphologic
    form and structure of organ
  2. Define: Functional
    function or job of organ
  3. Morphological RV normal characteristics: (5)
    • triangle shape
    • course trabeculations
    • attach pap to IVS
    • moderator band
    • trileaflet valve
  4. morphologic LV characteristics are: (4)
    • conical shape
    • smooth interior surface
    • 2 clearly defined pap muscles
    • bileaflet valve (bicuspid)
  5. Morphologic RA characteristics are:
    • drain coronary sinus, IVC, SVC
    • Larger appendage than LA
    • Could drain some / all PV (anomalous PV drain)
  6. Morphologic LA characteristics include:
    • doesn't drain any systemic veins
    • drains ALL pulmonary veins
  7. Name 2 stable anatomical relationships in CHD:
    • 1. visceroatrial situs
    • 2. relationship of AV valves & ventricles
  8. Define: atrioventricular alignment
    describes which atrium opens to which ventricle
  9. Define: Concordance
    • RA opens into RV
    • LA opens into LV
  10. Define: Discordance
    • RA opens into LV (through MV)
    • LA opens into RV (through TV)
  11. Cardiac Positions:
    Lie in Rt Chest =
    Lie in Lt Chest =
    Lie in Midline =
    Situs Solitus =
    Situs Inversus =
    • Dextrocardia
    • Levocardia
    • Mesocardia
    • Normal lie
    • Rt-->Lt position of unpaired organs of body (dextrocardia)
  12. Cardiac situs is determined by the position of ________________ because they MC consistant relation to situs of viscera.
    atria
  13. 3 causes of dextrocardia are:
    • 1. mechanical - dextroposition - heart rt chest; apex pts left
    • 2. situs inversus - dextrocardia - rt chest; apex rt
    • 3. early fetus - dextroversion - lt chest; apex pt rt
  14. Levoversion of situs inversus =
    opposite of dextroversion of situs solitus

    right chest; apex pt left
  15. Mesocardia =
    midline arrest of normal cardiac rotation in situs solitus or situs inversus
  16. How does one begin a pediatric echo?
    subcostal
  17. Define: Situs
    normal or original position, as of a body organ or part
