We describe two cases, a 23-year-old girl with dilated cardiomyopathy who presented with progressive dyspnea and fatigue and a 28-year-old girl with hypertrophic cardiomyopathy who was asymptomatic, secondary to the accumulation of amylopectin-like fibrillar glycogen, in heart. In both patients, the diagnosis was confirmed by enzyme assessment. Our patients showed that GSD IV is not only liver or skeletal muscle disease, but also it can be presented in different form of the spectrum of cardiomyopathy from dilated to hypertrophic and from asymptomatic to decompensated heart failure. Also, to our knowledge, this is the first hypertrophic cardiomyopathy case due to GSD IV in the literature.<\/jats:p>","DOI":"10.1155\/2012\/764286","type":"journal-article","created":{"date-parts":[[2012,9,27]],"date-time":"2012-09-27T14:45:10Z","timestamp":1348757110000},"page":"1-4","source":"Crossref","is-referenced-by-count":21,"title":["Cardiac Involvement in Glycogen Storage Disease Type IV: Two Cases and the Two Ends of a Spectrum"],"prefix":"10.1155","volume":"2012","author":[{"given":"Tolga","family":"Aksu","sequence":"first","affiliation":[{"name":"Department of Cardiology, Kocaeli Derince Education and Research Hospital, 41900 Kocaeli, Turkey"},{"name":"Department of Cardiology, Ankara Yuksek Ihtisas Education and Research Hospital, Sihhiye, 06410 Ankara, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ayse","family":"Colak","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Ankara Yuksek Ihtisas Education and Research Hospital, Sihhiye, 06410 Ankara, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Omac","family":"Tufekcioglu","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Ankara Yuksek Ihtisas Education and Research Hospital, Sihhiye, 06410 Ankara, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"98","reference":[{"issue":"1","key":"1","first-page":"11","volume":"5","year":"1956","journal-title":"Laboratory Investigation"},{"issue":"2","key":"2","doi-asserted-by":"crossref","first-page":"725","DOI":"10.1073\/pnas.56.2.725","volume":"56","year":"1966","journal-title":"Proceedings of the National Academy of Sciences of the United States of America"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1007\/BF01799348"},{"issue":"4","key":"4","doi-asserted-by":"crossref","first-page":"419","DOI":"10.1007\/BF00334454","volume":"85","year":"1993","journal-title":"Acta Neuropathologica"},{"issue":"1","key":"5","doi-asserted-by":"crossref","first-page":"51","DOI":"10.1016\/S0022-3476(87)80341-4","volume":"111","year":"1987","journal-title":"Journal of Pediatrics"},{"issue":"2","key":"6","doi-asserted-by":"crossref","first-page":"177","DOI":"10.2174\/1566524024605815","volume":"2","year":"2002","journal-title":"Current Molecular Medicine"},{"issue":"2","key":"7","first-page":"S43","volume":"158","year":"1999","journal-title":"European Journal of Pediatrics"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1111\/j.1399-3046.2007.00803.x"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM199303183281101"},{"issue":"11","key":"10","doi-asserted-by":"crossref","first-page":"1698","DOI":"10.1093\/oxfordjournals.eurheartj.a060797","volume":"16","year":"1995","journal-title":"European Heart Journal"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1007\/s003920050361"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1038\/35022604"}],"container-title":["Case Reports in Medicine"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/crim\/2012\/764286.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/crim\/2012\/764286.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/crim\/2012\/764286.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2017,6,21]],"date-time":"2017-06-21T00:43:25Z","timestamp":1498005805000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/crim\/2012\/764286\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2012]]},"references-count":12,"alternative-id":["764286","764286"],"URL":"https:\/\/doi.org\/10.1155\/2012\/764286","relation":{},"ISSN":["1687-9627","1687-9635"],"issn-type":[{"value":"1687-9627","type":"print"},{"value":"1687-9635","type":"electronic"}],"subject":[],"published":{"date-parts":[[2012]]}}}
