Routine preoperative computed tomography or cardiac magnetic resonance planning and intraoperative transoesophageal echocardiography were performed in each of the studied patients. Major technical features were identified and complemented during septal myectomy of the calcified interventricular septum.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>RESULTS<\/jats:title>\n                  <jats:p>The mean age of the studied patients accounted 50.5\u2009\u00b1\u200914.6, median\u201454; males\u20145 (31.3%). Mean cross-clamp time accounted 52\u2009\u00b1\u20097.2\u2009min. Calcified basal interventricular septum was identified in 2 (12.5%) patients. No iatrogenic ventricular septal defect (0%) was made during surgical correction. Peak systolic pressure gradient decreased from 86 (interquartile range: 75\u2013104.7) to 20 (16\u201322) mmHg (P&amp;lt;\u20090.001). No patients with moderate or severe mitral regurgitation were identified, whereas before the procedure, the number of those accounted 13 (81.2%) individuals. In-hospital and overall mortality after septal myectomy accounted 0%.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>CONCLUSIONS<\/jats:title>\n                  <jats:p>Extended septal myectomy in patients who previously underwent alcohol septal ablation is a safe procedure that affects all pathological manifestations of the disease. Routine preoperative computed tomography or cardiac magnetic resonance provides detailed anatomy of the anomalous left ventricle and subvalvular structures and allows to measure the extension of myectomy preventing the occurrence of iatrogenic ventricular septal defect. Septal myectomy of the calcified interventricular septum requires avoidance of \u2018one-piece technique\u2019 since fragmental myectomy allows visually control the adequacy of the left ventricle outflow tract release.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1093\/icvts\/ivac010","type":"journal-article","created":{"date-parts":[[2022,1,27]],"date-time":"2022-01-27T20:12:48Z","timestamp":1643314368000},"page":"723-730","source":"Crossref","is-referenced-by-count":7,"title":["Septal myectomy with mitral valve surgery in patients after alcohol septal ablation"],"prefix":"10.1093","volume":"34","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1508-9293","authenticated-orcid":false,"given":"Kostiantyn V","family":"Rudenko","sequence":"first","affiliation":[{"name":"Department of Myocardial Pathology, Heart Transplantation and Mechanical Circulatory Support, Amosov National Institute of Cardiovascular Surgery NAMS of Ukraine, Kyiv, Ukraine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1748-561X","authenticated-orcid":false,"given":"Vasyl V","family":"Lazoryshynets","sequence":"additional","affiliation":[{"name":"Department of Surgical Treatment of Congenital Heart Diseases in Infants, Amosov National Institute of Cardiovascular Surgery NAMS of Ukraine, Kyiv, Ukraine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6232-4225","authenticated-orcid":false,"given":"Lidiia O","family":"Nevmerzhytska","sequence":"additional","affiliation":[{"name":"Department of Myocardial Pathology, Heart Transplantation and Mechanical Circulatory Support, Amosov National Institute of Cardiovascular Surgery NAMS of Ukraine, Kyiv, Ukraine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9758-0018","authenticated-orcid":false,"given":"Mariia O","family":"Tregubova","sequence":"additional","affiliation":[{"name":"Department of Radiology, Amosov National Institute of Cardiovascular Surgery NAMS of Ukraine, Kyiv, Ukraine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2111-7510","authenticated-orcid":false,"given":"Polina A","family":"Danchenko","sequence":"additional","affiliation":[{"name":"Department of Surgery with Course of Emergency and Vascular Surgery, Bogomolets National Medical University, Kyiv, Ukraine"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2022,2,1]]},"reference":[{"key":"2022050515343012700_ivac010-B1","first-page":"e533","article-title":"2020 AHA\/ACC guideline for the diagnosis and treatment of patients with hypertrophic cardiomyopathy: executive summary: a report of the American College of Cardiology\/American Heart Association Joint Committee on Clinical Practice Guidelines","volume":"142","author":"Ommen","year":"2020","journal-title":"Circulation"},{"key":"2022050515343012700_ivac010-B2","doi-asserted-by":"crossref","first-page":"2733","DOI":"10.1093\/eurheartj\/ehu284","article-title":"2014 ESC Guidelines on diagnosis and management of hypertrophic cardiomyopathy: the Task Force for the Diagnosis and Management of Hypertrophic Cardiomyopathy of the European Society of Cardiology (ESC)","volume":"35","author":"Elliott","year":"2014","journal-title":"Eur Heart J"},{"key":"2022050515343012700_ivac010-B3","doi-asserted-by":"crossref","first-page":"196","DOI":"10.1161\/CIRCULATIONAHA.107.691378","article-title":"Controversies in cardiovascular medicine.
