Mapping and ablation of the clinical VT is often limited when the VT is noninducible, nonsustained or not haemodynamically tolerated. Substrate-based ablation strategies have been developed in an aim to treat VT in this setting and, subsequently, have been shown to improve outcomes in VT ablation when compared to focused ablation of mapped VTs. Since the initial description of linear ablation lines targeting ventricular scar, many different approaches to substrate-based VT ablation have been developed. Strategies can broadly be divided into three categories: 1) targeting abnormal electrograms, 2) anatomical targeting of conduction channels between areas of myocardial scar, and 3) targeting areas of slow and/or decremental conduction, identified with \"functional\" substrate mapping techniques. This review summarises contemporary substrate-based ablation strategies, along with their strengths and weaknesses.","is_dataset_classified":null,"base_score":2.8903717578961645,"endowment":2.8903717578961645,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"36007824","pmcid":"PMC9649336","openalex_id":"https://openalex.org/W4292689102","authors":[],"funders":[{"funder_name":"Abbott Laboratories","grant_id":"","title":null},{"funder_name":"Sanofi","grant_id":"","title":null},{"funder_name":"Medtronic","grant_id":"","title":null},{"funder_name":"National Health and Medical Research Council","grant_id":"","title":null},{"funder_name":"Biosense Webster","grant_id":"","title":null}],"total_grants":5,"fwci":2.1533,"citation_percentile":0.88901976,"influential_citations":0,"citation_trend":[{"year":2022,"count":1},{"year":2023,"count":5},{"year":2024,"count":4},{"year":2025,"count":4},{"year":2026,"count":3}],"oa_status":"gold","license":"cc-by-nc-nd","oa_locations":[{"url":"https://doi.org/10.1016/j.ipej.2022.08.002","host_type":"journal"},{"url":"https://doi.org/10.1016/j.ipej.2022.08.002","host_type":"publisher"},{"url":"https://api.elsevier.com/content/article/PII:S0972629222001097?httpAccept=text/xml","host_type":"publisher"},{"url":"https://api.elsevier.com/content/article/PII:S0972629222001097?httpAccept=text/plain","host_type":"publisher"},{"url":"https://pubmed.ncbi.nlm.nih.gov/36007824","host_type":"repository"},{"url":"https://doaj.org/article/8236ce4f070a43faa29ddf7b912d0f74","host_type":"repository"},{"url":"https://www.ncbi.nlm.nih.gov/pmc/articles/9649336","host_type":"repository"},{"url":"https://europepmc.org/articles/PMC9649336","host_type":"Europe_PMC"},{"url":"https://europepmc.org/articles/PMC9649336?pdf=render","host_type":"Europe_PMC"}],"fields_of_study":["Cardiac Arrhythmias and Treatments","Cardiac electrophysiology and arrhythmias","Atrial Fibrillation Management and Outcomes"],"mesh_terms":[],"keywords":["Ablation","Medicine","Ventricular tachycardia","Catheter ablation","Cardiology","Internal medicine","Substrate (aquarium)","Tachycardia","Cardiac Ablation","Ventricular Arrhythmias","Ilam","Functional Substrate Mapping"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Good health and well-being"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[{"name":"doi"}],"source":"live","citation_network_status":"fetched"},"created_at":"2026-07-29T05:38:35.525630Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
