The current state
We address the absence of an intra-operative evaluation tool during valve-sparing aortic root replacement and aortic valve repair operations.
A valve-sparing aortic root replacement procedure is recommended by the ESC/EACTS (Guidelines for the management of valvular heart disease), in patients with aortic root aneurism. The alternative, a composite valved graft replacement procedure (i.e. Bentall of Biobentall procedure) is less preferable due to the disadvantages of a prosthetic valve.
On a yearly basis, we estimate the number of operations in continental Europe, for aortic root enlargement and valve regurgitation to be 6,300 patients.
At this point the operative procedure does not allow the team to inspect the spared or repaired aortic valve in a detailed way during the operation, simply because no tool or inspection method exists to date.
We set out to contribute to a solution for this problem.
