However, there are no case reports in which revascularization dramatically improved left ventricular function in patients with progressive decline in left ventricular function. Herein, we present a rare case in which the left ventricular function was dramatically improved by surgical treatment for progressive left ventricular dysfunction due to atypical coarctation of the aorta.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case presentation<\/jats:title>\n                    <jats:p>A 58-year-old man underwent left axillary artery-bilateral femoral artery bypass at another hospital for atypical coarctation of the aorta due to Takayasu\u2019s arteritis. Approximately 10\u00a0years later, he was re-hospitalized for heart failure, and the left ventricular ejection fraction gradually decreased to 28%. Computed tomography showed severe calcification and stenosis at the same site from the peripheral thoracic descending aorta to the lower abdominal aorta of the renal artery, and aortography showed delayed bilateral renal artery blood flow. An increase in plasma renin activity was also observed. Despite the administration of multiple antihypertensive drugs, blood pressure control was insufficient. We decided to perform surgical treatment to improve progressive cardiac dysfunction due to increased afterload and activated plasma renin activity. Descending thoracic aorta-abdominal aorta bypass and revascularization of the bilateral renal arteries via the great saphenous vein grafts were performed. Postoperative blood pressure control was improved, and the dose of antihypertensive drugs could be reduced. Plasma renin activity decreased, and transthoracic echocardiography 1.5\u00a0years later showed an improvement in contractility with a left ventricular ejection fraction of 58%.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>In atypical coarctation of the aorta in patients with decreased bilateral renal blood flow, heart failure due to renal hypertension, and progressive decrease in left ventricular contractility, descending thoracic aorta-abdominal aortic bypass and bilateral renal artery recirculation can be extremely effective.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1186\/s13019-021-01598-5","type":"journal-article","created":{"date-parts":[[2021,8,4]],"date-time":"2021-08-04T05:03:05Z","timestamp":1628053385000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Descending thoracic aorta\u2013abdominal aortic bypass and bilateral renal arterial blood circulation reconstruction are effective in atypical coarctation of the aorta with heart failure: a case report"],"prefix":"10.1186","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4948-4005","authenticated-orcid":false,"given":"Takuma","family":"Mikami","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takeshi","family":"Kamada","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Toshiyuki","family":"Yano","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tomohiro","family":"Nakajima","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Naomi","family":"Yasuda","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tsuyoshi","family":"Shibata","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Keitaro","family":"Nakanishi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ryo","family":"Harada","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Syuichi","family":"Naraoka","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kojiro","family":"Toda","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nobutaka","family":"Nagano","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Atsuko","family":"Muranaka","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nobuyoshi","family":"Kawaharada","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2021,8,4]]},"reference":[{"issue":"5","key":"1598_CR1","doi-asserted-by":"publisher","first-page":"820","DOI":"10.1536\/ihj.16-463","volume":"58","author":"M Ishizuka","year":"2017","unstructured":"Ishizuka M, Yamada S, Maemura S, Yamamoto K, Takizawa M, Uozumi H, et al.
