D-Transposition of the great arteries
Ans- LV/RV normal orientation. Aorta leaves RV, Pulm Valve leaves LV
- Needs balloon septostomy, otherwise not compatible with life
L-Transposition of the great arteries (Congenitally corrected transposition)
Ans- The aorta arises from the ventricle that is...
Ans- LVOT area = pi (LVOT diameter/ 2)^2 = 0.785 x LVOT diameter^2
, AVA (continuity equation)
Ans- AVA = LVOT area x LVOT VTI / AV VTI
Pressure half time (PHT) relation to declaration time (DT)
Ans- PHT is 29% of DT
PHT = 0.29 x DT
Mitral valve area (MVA) calculation from PHT
Ans- MVA = 220 / PHT
Bernoulli Equation
Ans- Pressure gradient = 4V^2
Bernoulli Equation for:
RVSP =
PAEDP = (Pulm valve)
