Why the study?
Evaluating TAVI feasibility in bicuspid aortic valve anatomy with an annular perimeter around 100 mm, which exceeds recommended instructions for use sizing.
Can transcatheter aortic valve implantation be successfully performed in patients with bicuspid aortic valves and extremely large annuli (~100 mm perimeter)?
Can transcatheter aortic valve implantation be successfully performed in patients with bicuspid aortic valves and extremely large annuli (~100 mm perimeter)?
TAVI can be successfully performed using specific techniques in patients with bicuspid aortic valves and extremely large annuli that exceed standard commercial valve sizing recommendations.
Initial cases suggest TAVI feasibility beyond IFU in large BAV; leaves open need for dedicated sizing data and prospective validation.
We describe our initial experience with four consecutive cases of transcatheter aortic valve implantation (TAVI) in bicuspid aortic valve (BAV) anatomy with an annular perimeter in range of 100 mm which is beyond the range of any of the recommended sizes as per instructions for use (IFU) for an appropriate size valve from any of the commercially existing makes of transcatheter valves. The techniques used and principles applied for doing a successful transcatheter procedure in these cases are presented.
