Abstract
We propose an angle independent method for quantification of flow through composite surfaces covering the cross section of cardiac inflow and outflow tracts. We interleave trigger-delayed 3D colour Doppler sequences to increase frame rate and use multiple views to increase coverage.
Our method is applied to four patients with Hypoplastic Left Heart Syndrome (HLHS). Flow and velocity measurement are compared to Phase Contrast Magnetic Resonance Imaging (PC-MRI). Results are highly time-resolved and agree well with PC-MRI and show superior performance compared to standard measurements. Mean dissimilarity with respect to PC-MRI was found to be 7.35% ±3.72% (neoaortic outflow) and 10.15% ±2.72% (tricuspid inflow).
