Physical examination showed signs concerning for cardiac tamponade in the presence of hypotension. Echocardiography showed a large amount of hemopericardium. We then injected intravenous contrast that became visible within the pericardial space. Chest computed tomography showed Type A aortic dissection. The patient was transferred to a higher-level facility for intervention. We share this rare presentation of spontaneous aortic dissection complicated by cardiac tamponade and hemopericardium.<\/jats:p>","DOI":"10.4103\/heartviews.heartviews_49_24","type":"journal-article","created":{"date-parts":[[2025,1,4]],"date-time":"2025-01-04T09:00:17Z","timestamp":1735981217000},"page":"179-182","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":0,"title":["Aortic Dissection Presenting as Cardiac Tamponade with Hemopericardium Initially Identified by Echocardiography"],"prefix":"10.4103","volume":"25","author":[{"given":"Khalid","family":"Sawalha","sequence":"first","affiliation":[{"name":"University Health Truman Medical Center, University of Missouri-Kansas City, Kansas City, Missouri, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Angel","family":"L\u00f3pez-Candales","sequence":"additional","affiliation":[{"name":"Section of Cardiovascular Medicine, University Health Truman Medical Center, University of Missouri-Kansas City, Kansas City, Missouri, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2025,1,4]]},"reference":[{"key":"R1-20260423","doi-asserted-by":"crossref","first-page":"628","DOI":"10.1161\/01.CIR.0000087009.16755.E4","article-title":"Aortic dissection: New frontiers in diagnosis and management: Part I: From etiology to diagnostic strategies","volume":"108","author":"Nienaber","year":"2003","journal-title":"Circulation"},{"key":"R2-20260423","doi-asserted-by":"crossref","first-page":"3802","DOI":"10.1161\/CIRCULATIONAHA.105.534198","article-title":"Acute aortic syndromes","volume":"112","author":"Tsai","year":"2005","journal-title":"Circulation"},{"key":"R3-20260423","first-page":"e52677","article-title":"Hemopericardium: A comprehensive clinical review of etiology and diagnosis","volume":"16","author":"Borkowski","year":"2024","journal-title":"Cureus"},{"key":"R4-20260423","first-page":"694","article-title":"Aortic dissection: A 250-year perspective","volume":"38","author":"Criado","year":"2011","journal-title":"Tex Heart Inst J"},{"key":"R5-20260423","article-title":"Underlying Cause of Death 1999-2016 on CDC WONDER Online Database, Released December;
