    A 78-year-old female with severe prosthetic stenosis underwent open TAVR explantation and selective metal cell excision to preserve coronary access.

  • 2

    The intervention resolved severe stenosis and paravalvular leak, leading to sustained clinical improvement at six-month follow-up.

  • 3

    Selective metal cell excision is a feasible technique that maintains valve integrity while ensuring future coronary access during TAVR procedures.

  • 4

    Current re-intervention strategies for degenerated TAVR include valve-in-valve TAVR or surgical aortic valve replacement, each with significant limitations.

  • 5

    This case highlights the importance of considering coronary access in TAVR planning, especially for high-risk patients requiring future interventions.
