Innocent Murmurs of Childhood
- Carotid Bruit
- Venous Humm
- Pulmonary Flow Murmur
- Peripheral Pulmonic Stenosis
- Stills Murmur
Cyanotic Heart Murmurs
- Truncus Arteriosis
- Transposition
- Tricuspid Insufficiency
- TOF
- Total Anomalous Pulmonary Vasc Return
Murmur in TOF
What is a tetralogy spell?
Pulmonic Stenosis harsh murmur
A decreased or absent murmur signifies diminished pulmonary blood flow, as occurs in the
cyanotic spell or tetralogy spell. Such spells are marked by distress, crying, inconsolability,
hyperpnea, and increasing cyanosis
4 components of TOF
- overriding aorta
- RVH
- VSD
- Pulmonic Stenosis
The primary lesion is underdevelopment of the:
pulmonary infundibulum,
which has led some to refer to this disease as “monology of Fallot” because all aspects of the tetrad result from this lesion.
Paradoxic Emboli
result from Right to left shunt
Jervell-Lange-Nielsen
molecular defect in K channels causing QT prolongation
inheritence of Jervell-Lange-Neilsen
AR
prolong QT may lead to
torsades
Prolong QT treatment
Beta Blockers and Class II antiarrythmics
which class antiarrythmics prolongs QT
Class IA (Quinidine)
Tet spell
in TOF,
a RV outlet obstruction causes flow to cross VSD into aorta. Intervention necessary.
Squatting helps
harsh systolic murmur at left upper sternal border
single s2
crescendo-decrescendo
TOF
Tricuspid Valve Atresia
Left axis deviation
Hypoplastic left ventricle
left lower sternal border murmur
holosystolic murmur at left lower sternal border
beware of what
VSD
what keeps ductus open
