Biomechanics of Aortic Dissection: A Comparison of Aortas Associated With Bicuspid and Tricuspid Aortic Valves | Journal of the American Heart Association https://www.ahajournals.org/doi/10.1161/JAHA.120.016715#.XyIc91qrOyQ.twitter
Take homes:
1. In tests of material properties of the ascending aorta, BAV associated aneurysms were found to be stronger/less likely to dissect than TAV
1. In tests of material properties of the ascending aorta, BAV associated aneurysms were found to be stronger/less likely to dissect than TAV
2. Novel biomechanical parameter, ENERGY LOSS, has stronger association with the propensity to dissect than diameter or aortic stiffness.
and yes energy loss was significantly higher in TAV aortas! BAV aortas were stiffer tho.
and yes energy loss was significantly higher in TAV aortas! BAV aortas were stiffer tho.
IMPACT:
1. No need for lower size thresholds for BAV aneurysms
2. Energy loss is a promising biomarker for dissection risk that we are actively researching (keep eye out for more from us!)

Please read full paper for all the details. Very proud of our whole team - years of work to put all this together.
