The clinical manifestations of these anomalies depend on the distribution of collateral vessels.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Case summary<\/jats:title>\n                  <jats:p>A 55-year-old female presented with dyspnoea, mild chest pain during physical activity, and palpitations. Selective coronary angiography revealed a prominent SCA originating from the right coronary sinus. Approximately 2\u2005mm from the ostium, this artery branched into two: a dominant right coronary artery (RCA) and a smaller artery for the anterior wall perfusion. The dominant RCA then moved posteriorly, bifurcating into a posterior descending artery and a posterolateral artery. The latter occupied the expected location of the left circumflex artery and supplied the majority of the coronary circulation, including the left ventricle. Notably, there were no significant atherosclerotic calcifications or stenoses observed.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Discussion<\/jats:title>\n                  <jats:p>We describe a unique case of a SCA that doesn\u2019t conform to any category within the modified Lipton\u2019s classification. Symptoms are speculated to arise from the compression of the SCA between the aorta and pulmonary artery during physical exertion. Additionally, hypoperfusion from the hypoplastic left coronary branch in the anterior wall warrants consideration. It\u2019s paramount to meticulously evaluate the risk of sudden cardiac death when treating patients with a SCA. For high-risk patients, coronary artery bypass grafting should be contemplated.<\/jats:p>\n                  <jats:p>For our patient, given the clinical context, pharmacological treatment optimization was chosen.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1093\/ehjcr\/ytae017","type":"journal-article","created":{"date-parts":[[2024,1,8]],"date-time":"2024-01-08T15:17:04Z","timestamp":1704727024000},"source":"Crossref","is-referenced-by-count":1,"title":["Single dominant right coronary artery with hypoplastic left coronary branch: a rare congenital anomaly: a case report"],"prefix":"10.1093","volume":"8","author":[{"given":"Fadhel","family":"Hamidani","sequence":"first","affiliation":[{"name":"Cardiology Department, Clinic Neuendettelsau , Heilsbronner Str. 44 , Neuendettelsau 91564, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-3432-3966","authenticated-orcid":false,"given":"Blerim","family":"Berisha","sequence":"additional","affiliation":[{"name":"Cardiology Department, Clinic Neuendettelsau , Heilsbronner Str. 44 , Neuendettelsau 91564, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2024,1,8]]},"reference":[{"key":"2024012419415519400_ytae017-B1","doi-asserted-by":"crossref","first-page":"1637","DOI":"10.1093\/oxfordjournals.eurheartj.a060117","article-title":"Isolated single coronary artery: a review of 50,000 consecutive coronary angiographies","volume":"13","author":"Desmet","year":"1992","journal-title":"Eur Heart J"},{"key":"2024012419415519400_ytae017-B2","first-page":"121","article-title":"The primary anomalies of coronary artery origin and course: a coronary angiographic analysis of 16,573 patients","volume":"18","author":"Yuksel","year":"2013","journal-title":"Exp Clin Cardiol"},{"key":"2024012419415519400_ytae017-B3","doi-asserted-by":"crossref","first-page":"39","DOI":"10.1148\/130.1.39","article-title":"Isolated single coronary artery: diagnosis, angiographic classification, and clinical significance","volume":"130","author":"Lipton","year":"1979","journal-title":"Radiology"},{"key":"2024012419415519400_ytae017-B4","doi-asserted-by":"crossref","first-page":"28","DOI":"10.1002\/ccd.1810210110","article-title":"Coronary artery anomalies in 126,595 patients undergoing coronary arteriography","volume":"21","author":"Yamanaka","year":"1990","journal-title":"Cathet Cardiovasc Diagn"},{"key":"2024012419415519400_ytae017-B5","doi-asserted-by":"crossref","first-page":"e148","DOI":"10.1016\/j.jccase.2011.08.005","article-title":"Hypoplastic coronary artery disease: a rare cause of sudden cardiac death and its treatment with an implantable defibrillator","volume":"4","author":"McFarland","year":"2011","journal-title":"J Cardiol Cases"},{"author":"Aubry","key":"2024012419415519400_ytae017-B6"},{"key":"2024012419415519400_ytae017-B7","doi-asserted-by":"crossref","first-page":"2449","DOI":"10.1161\/01.CIR.0000016175.49835.57","article-title":"Coronary anomalies: incidence, pathophysiology, and clinical relevance","volume":"105","author":"Angelini","year":"2002","journal-title":"Circulation"},{"key":"2024012419415519400_ytae017-B8","doi-asserted-by":"crossref","first-page":"983","DOI":"10.1007\/s10554-016-0849-5","article-title":"Coronary arteries anomalous aortic origin on a computed tomography angiography population: prevalence, characteristics and clinical impact","volume":"32","author":"Amado","year":"2016","journal-title":"Int J Cardiovasc Imaging"},{"key":"2024012419415519400_ytae017-B9","first-page":"271","article-title":"Coronary artery anomalies\u2014current clinical issues: definitions, classification, incidence, clinical relevance, and treatment guidelines","volume":"29","author":"Angelini","year":"2002","journal-title":"Tex Heart Inst J"},{"key":"2024012419415519400_ytae017-B10","doi-asserted-by":"crossref","first-page":"31","DOI":"10.1097\/00045415-200111000-00005","article-title":"Congenital coronary artery anomalies as an important cause of sudden death in the young","volume":"9","author":"Basso","year":"2001","journal-title":"Cardiol Rev"}],"container-title":["European Heart Journal -
