Retrograde venous ethanol infusion (RVEI) can be a valuable alternative in this scenario. A 43\u2010year\u2010old woman without structural heart disease presented with LV summit PVCs unresponsive to RF ablation because of their deep\u2010seated origin. Unipolar pace mapping performed through a wire inserted into a branch of the distal great cardiac vein (GCV) demonstrated 12\/12 concordance with the clinical PVCs thus indicating close proximity to PVCs\u2019 origin. RVEI abolished the PVCs without complications. Subsequently, magnetic resonance imaging (MRI) evidenced an intramural myocardial scar produced by ethanol ablation. In\u00a0conclusion,\u00a0RVEI effectively and safely treated PVC arising from a deep site in the LVS. The scar provoked by chemical damage was well characterized by MRI imaging.<\/jats:p><\/jats:sec>","DOI":"10.1111\/pace.14680","type":"journal-article","created":{"date-parts":[[2023,2,22]],"date-time":"2023-02-22T10:40:05Z","timestamp":1677062405000},"page":"1235-1238","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Left ventricular summit premature ventricular contractions treated by venous ethanol infusion: Scar assessment by magnetic resonance imaging"],"prefix":"10.1111","volume":"46","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1600-3137","authenticated-orcid":false,"given":"Luca Rosario","family":"Limite","sequence":"first","affiliation":[{"name":"Service de Cardiologie H\u00f4pital Priv\u00e9 Les Franciscaines, ELSAN  N\u00eemes France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guillaume","family":"Laborie","sequence":"additional","affiliation":[{"name":"Service de Cardiologie H\u00f4pital Priv\u00e9 Les Franciscaines, ELSAN  N\u00eemes France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Justine","family":"Constantin","sequence":"additional","affiliation":[{"name":"Biosense Webster France Johnson &amp;
