Key result
The coexistence of coarctation of the aorta and a bicuspid aortic valve significantly alters blood flow, increasing maximal velocity downstream of the coarctation to 3.0 m/s compared to 1.9 m/s with an isolated coarctation.
Why the study?
Does the presence of a bicuspid aortic valve alter aortic hemodynamics in models of coarctation of the aorta?
Does the presence of a bicuspid aortic valve alter aortic hemodynamics in models of coarctation of the aorta?
Absolute Event Rate: 3% vs 1.9%
The presence of a bicuspid aortic valve in coarctation of the aorta significantly worsens adverse hemodynamic forces, providing a biomechanical explanation for the higher risk of aortic complications in these patients.

May explain higher aortic complication risk in COA with BAV; leaves open need for human validation studies.
Keshavarz‐Motamed et al. (2013) studied Coarctation of the aorta and bicuspid aortic valve. Bicuspid aortic valve (complex COA) vs. Normal tricuspid aortic valve (isolated COA) was evaluated on Maximal velocity downstream of the coarctation. The coexistence of coarctation of the aorta and a bicuspid aortic valve significantly alters blood flow, increasing maximal velocity downstream of the coarctation to 3.0 m/s compared to 1.9 m/s with an isolated coarctation.
