The findings in 4 children with heart tumors are reported: a rhabdomyosarcoma, a rhabdomyoma, a fibroma and a myxoma. The symptoms depend upon the location (intrapericardial, intramural or intracavitary). ECG and X-ray provide no essential diagnostic information; echocardiography can give a decisive diagnostic indication in parietal and intracavitary tumors. Surgery provides a specimen for histology, but the tumor cannot always be removed. The prognosis, therefore, depends upon the result of surgery, but malignant tumors, mostly being diagnosed too late, have a very bad prognosis.<\/jats:p>","DOI":"10.1159\/000173224","type":"journal-article","created":{"date-parts":[[2008,11,10]],"date-time":"2008-11-10T05:48:13Z","timestamp":1226296093000},"page":"12-22","source":"Crossref","is-referenced-by-count":24,"title":["Primary Heart Tumors in Infancy and Childhood Report of Four Cases and Review of Literature"],"prefix":"10.1159","author":[{"given":"A.A.","family":"Schmaltz","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.","family":"Apitz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2008,11,7]]},"container-title":["Cardiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000173224","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T16:25:24Z","timestamp":1777479924000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000173224"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2008,11,7]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000173224","archive":["Portico"],"relation":{},"ISSN":["0008-6312","1421-9751"],"issn-type":[{"value":"0008-6312","type":"print"},{"value":"1421-9751","type":"electronic"}],"subject":[],"published":{"date-parts":[[2008,11,7]]}}}
