Abstract
Hypoplastic left heart syndrome (HLHS) is one kind of
congenital heart diseases of newborn. The surgeries for
HLHS have to be carried out at very early stage. However,
currently there are no quantitative standard to evaluate and
predict the outcome of the therapy. In this study,
computational fluid dynamics (CFD) is introduced
simulate the hemodynamics after Norwood surgery; a first
stage surgery for HLHS. Blood flows derived from
Echocardiography measurements were used as boundary
conditions for pulsatile calculation. The circulations of
blood flows were observed and the flow distribution in
each vessel is estimated. Energy losses (EL), local
pressure, and wall shear stress (WSS) in anastomosis were
analyzed to estimate the result of HLHS treatment. The
results indicate that pulsatile simulation is essential to
quantitatively evaluate the quality of HLHS operation, and
the method of computational hemodynamics analysis
could be applied into the process of the operations for
surgical optimization.
