Abstract
Trans-catheter aortic valve replacement (TAVR) via tortuous iliofemoral access with prior endovascular aneurysm repair (EVAR) is challenging. 83 year old male with severe aortic stenosis and prior EVAR was evaluated for TAVR with 29 mm Edwards Sapien 3 valve. Right femoral access was planned with ipsilateral protection. CT angiogram showed EVAR with tortuosity, rigidity, and graft protrusion concerning for advancement of equipment. The right iliofemoral system was accessed using a 4F radial sheath, Judkins JR4 catheter, and 0.035” angled glide wire exchanged for Amplatz Superstiff wire. A 30 cm 6F sheath was advanced over the wire followed by additional Superstiff buddy wire. Two Proglides were deployed over two separate wires, without rewiring. To overcome friction on removing second Proglide, predilatation of the arteriotomy should have been performed with a 8-9F sheath. An 8F sheath was advanced over one of two Superstiff wires. A V18 0.018” wire was placed in the ipsilateral protect site, exchanged for a third Superstiff wire to ease insertion of the Edwards sheath. The sheath was advanced followed by successful valve deployment. After removing the delivery system, two pre-deployed Proglides closed the arteriotomy site. Detailed planning enables operators to overcome challenges using the following strategies: 1) avoid unnecessary rewiring of the iliofemoral system by use of a 30 cm 6F sheath, 2) predilate the TAVR arteriotomy with larger sheaths prior to deploying Proglides to avoid limited manipulation space for Proglides and two wires, 3) use buddy wires if TAVR sheath advancement has failed over one wire and consider additional buddy wires from within the TAVR arteriotomy or ipsilateral protection site, and 4) use ipsilateral protection to avoid challenges of crossing over from contralateral iliofemoral. Although trans-EVAR TAVR remains somewhat unpredictable, these strategies may simplify and reduce the inherent failure rate of such procedures.
