AI-use statement:
The PubMed search strategy was drafted with the PICO search builder. It used the large language model claude-opus-5-5 (Anthropic; accessed October 28, 2026) to propose search concepts and terms from the review question. The tool made 1 call to the model at high effort (the draft); claude-opus-5-5 was requested and answered it. A refusal fallback was enabled (had the model declined a request, the API could have run it again on another model Anthropic recommends); it was not used. Every MeSH heading, Supplementary Concept and publication type the strategy searches was checked against NLM MeSH (id.nlm.nih.gov) before use: 11 valid. Each numbered line was run in PubMed through NCBI E-utilities on October 28, 2026, and PubMed's own diagnostics (phrases not found, ignored words, lost truncation) were checked. The strategy was tested against 1 known relevant study that was not shown to the model: 1 was retrieved (95% CI 3%–100%). Retrieving known studies does not prove the search is complete. A searcher must review the strategy before it is used. The prompts, the model output and every version are in the provenance file (JSON export).

Review question: Search terms included ‘transcatheter aortic valve replacement’ or ‘transcatheter aortic valve implantation’ or ‘TAVR’ or ‘TAVI’ and ‘transfemoral’ or ‘subclavian’ or ‘transsubclavian’ or ‘axillary’ or ‘transaxillary’ or ‘carotid’ or ‘transcarotid’ or ‘cava’ or ‘caval’ or ‘transcaval’.
