Aggressive aortic resection strategies for bicuspid
aortic valve (BAV) patients with significant aortopathy
are sometimes warranted. Recent evidence has shown that
4D flow MRI can identify regions of the aorta with
elevated wall shear stress (WSS) that may be at risk of
disease progression and thus may require resection
during aneurysm repair. This study assessed the efficacy
of standard aortic resection practices at our instition
to include tissue areas at risk as determined by pre-
and post-operative imaging. In selected patients with
BAV, aggressive resection using open distal/hemi-arch
repair acheived complete resection of tissue at risk of
disease progression.
