HOW WOULD I APPROACH IT? The authors present a case of retrogradely uncrossable aortic valve for transcatheter aortic valve implantation (TAVI). This happens with the valve introducer sheath in the femoral artery, and the remaining catheterized accesses. Therefore, a solution to implantation is needed since 1 of the basic steps is missing. There are 3 situations when crossing a stenosed aortic valve can become especially difficult even for an experienced operator: one is stenosed surgical aortic valves where the ascending aorta is poorly dilated compared to the artificial valve. In this situation, building the latter prevents proper catheter alignment.Another situation is critical aortic stenosis due to small opening orifice. The third situation is bicuspid valves, as it is the case here, with an often dilated ascending aorta or a too vertical valvular plane that complicate maneuvers with the guide catheter. Also, because the bicuspid opening being eccentric often complicates steering the guidewires and the catheters through the valvular orifice. If we exhaust all retrograde crossing possibilities with different catheters and guidewires, the only option left is antegrade access from the left ventricle (LV) through transseptal catheterization. The use of antegrade access for implantation purposes has already been described in the history of structural... |
