Comprehensive assessment of aortic flow before and after aortic valve replacement in an <i>ex vivo</i> porcine model with four-dimensional flow magnetic resonance imaging
We successfully established an ex vivo model suggesting that flow alterations not only depend on the type of AVR but are associated with surgical access. The strongest secondary flow patterns developed after BV followed by AVneo and MV.
