Ventricular pacing using a bipolar catheter was performed at a rate slightly higher than intrinsic sinus rate to mimic VT. The myocardium at the tip of the pacing catheter was targeted for ablation. Ablation endpoint was loss of ventricular capture first and confirmed by electrical nonexcitation with 10\u2010mA, 2\u2010ms pulse\u2010width unipolar stimulation.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Optimal ablation energy was identified at 400 W for 2\u20134 seconds. In five separate experimental preparations, pacing could be terminated successfully during HIFU energy delivery, which was further confirmed by electrical nonexcitation. However, capture could be obtained at other nonablated locations using the same pacing catheter. Both transmural and localized lesions could be created in a controlled fashion without apparent injury to skin, lung, or pericardium on postmortem examination.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>This pilot study suggests that HIFU is potentially useful for noninvasive ablation of targeted, localized myocardial tissues, and it may be potentially applicable for VT ablation, particularly for those with intramyocardial\/epicardial origins.<\/jats:p><\/jats:sec>","DOI":"10.1111\/jce.13459","type":"journal-article","created":{"date-parts":[[2018,2,12]],"date-time":"2018-02-12T11:23:38Z","timestamp":1518434618000},"page":"788-794","source":"Crossref","is-referenced-by-count":15,"title":["A feasibility study of noninvasive ablation of ventricular tachycardia using high\u2010intensity focused ultrasound"],"prefix":"10.1111","volume":"29","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2615-0122","authenticated-orcid":false,"given":"Fei","family":"L\u00fc","sequence":"first","affiliation":[{"name":"Deborah Heart and Lung Center Browns Mills  New Jersey USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"Huang","sequence":"additional","affiliation":[{"name":"Chongqing Medical University  Chongqing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8511-6920","authenticated-orcid":false,"given":"David G.","family":"Benditt","sequence":"additional","affiliation":[{"name":"University of Minnesota  Minneapolis MN USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2018,3,6]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8167.2009.01686.x"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11684-010-0092-8"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.100.2.203"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.echo.2007.03.007"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1093\/europace\/eup299"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1002\/uog.8830"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.1540-8175.2000.00563.x"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8167.2011.02084.x"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCEP.111.967216"},{"key":"e_1_2_6_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijcard.2013.01.235"},{"key":"e_1_2_6_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.echo.2013.06.020"},{"key":"e_1_2_6_13_1","first-page":"501","article-title":"High intensity focused ultrasound ablation for atrial fibrillation: Results from the National Spanish Registry","volume":"2016","author":"Reyes G","year":"2016","journal-title":"Minerva Cardioangiol"},{"key":"e_1_2_6_14_1","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.96.11.4044"},{"key":"e_1_2_6_15_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2013.02.050"},{"key":"e_1_2_6_16_1","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.0000030187.39852.A7"},{"key":"e_1_2_6_17_1","doi-asserted-by":"publisher","DOI":"10.1152\/ajpheart.01045.2001"},{"key":"e_1_2_6_18_1","doi-asserted-by":"publisher","DOI":"10.3171\/jns.1954.11.5.0471"},{"key":"e_1_2_6_19_1","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCEP.108.807925"}],"container-title":["Journal of Cardiovascular Electrophysiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1111%2Fjce.13459","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/jce.13459","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,9,23]],"date-time":"2023-09-23T15:41:49Z","timestamp":1695483709000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/jce.13459"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,3,6]]},"references-count":18,"journal-issue":{"issue":"5","published-print":{"date-parts":[[2018,5]]}},"alternative-id":["10.1111\/jce.13459"],"URL":"https:\/\/doi.org\/10.1111\/jce.13459","archive":["Portico"],"relation":{},"ISSN":["1045-3873","1540-8167"],"issn-type":[{"value":"1045-3873","type":"print"},{"value":"1540-8167","type":"electronic"}],"subject":[],"published":{"date-parts":[[2018,3,6]]}}}
