Embolic strokes are recognised as a rare complication of intracardiac blood cysts, with very few cases previously reported. Echocardiography was first used to identify a blood cyst in 1983 and remains an excellent modality to diagnose this rare condition.<\/jats:p>","DOI":"10.1136\/bcr.10.2011.5027","type":"journal-article","created":{"date-parts":[[2012,7,3]],"date-time":"2012-07-03T14:30:13Z","timestamp":1341325813000},"page":"bcr1020115027","source":"Crossref","is-referenced-by-count":5,"title":["A heart within the heart \u2013 a rare congenital cause of an embolic stroke"],"prefix":"10.1136","volume":"2012","author":[{"given":"Tina","family":"Khan","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Samy","family":"El-Sharkawy","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Frank","family":"Schafer","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2012,7,3]]},"reference":[{"unstructured":"Burke A Virmani R .
