Aim: We hypothesized that different cardiac structural changes underlie PPCM and DCM, and we aimed to investigate them with cardiovascular magnetic resonance (CMR). Methods: We included 21 PPCM patients (30.5 \u00b1 5.9 years) and 30 female DCM patients (41.5 \u00b1 16.8 years) matched for left ventricular ejection fraction. Biventricular and biatrial volumetric and functional parameters were assessed along with ventricular and atrial strain indices based on feature-tracking techniques. The presence of late gadolinium enhancement (LGE) was also assessed. Results: In PPCM, the left ventricular (LV) stroke volume index was lower (p = 0.04), right atrial (RA) minimal and pre-systolic volumes were higher (p &lt; 0.01 and p = 0.02, respectively), and the total RA ejection fraction was lower (p = 0.02) in comparison to DCM. Moreover, in PPCM, the LV global longitudinal strain (p = 0.03), global circumferential strain rate (p = 0.04), and global longitudinal strain rate (p &lt; 0.01) were less impaired than in DCM. Both PPCM and DCM patients with LGE had more dilated ventricles and more impaired LV and left atrial function than in PPCM and DCM patients without LGE. Conclusions: Subtle differences appear on CMR between PPCM and DCM. Most importantly, the RA is larger and more impaired, and LV global longitudinal strain is less reduced in PPCM than in DCM. Furthermore, similarly to DCM, PPCM patients with LGE have more dilated and impaired ventricles than patients without LGE.<\/jats:p>","DOI":"10.3390\/diagnostics11101752","type":"journal-article","created":{"date-parts":[[2021,9,24]],"date-time":"2021-09-24T20:15:32Z","timestamp":1632514532000},"page":"1752","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Cardiovascular Magnetic Resonance in Peripartum Cardiomyopathy: Comparison with Idiopathic Dilated Cardiomyopathy"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6622-5315","authenticated-orcid":false,"given":"Joanna","family":"Petryka-Mazurkiewicz","sequence":"first","affiliation":[{"name":"Department of Coronary and Structural Heart Diseases, National Institute of Cardiology, 04-628 Warsaw, Poland"},{"name":"Magnetic Resonance Unit, National Institute of Cardiology, 04-628 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Karolina","family":"Kryczka","sequence":"additional","affiliation":[{"name":"Department of Coronary and Structural Heart Diseases, National Institute of Cardiology, 04-628 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"\u0141ukasz","family":"Mazurkiewicz","sequence":"additional","affiliation":[{"name":"Department of Cardiomyopathy, National Institute of Cardiology, 04-628 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Barbara","family":"Mi\u0142osz-Wieczorek","sequence":"additional","affiliation":[{"name":"Magnetic Resonance Unit, National Institute of Cardiology, 04-628 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mateusz","family":"\u015apiewak","sequence":"additional","affiliation":[{"name":"Magnetic Resonance Unit, National Institute of Cardiology, 04-628 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Magdalena","family":"Marczak","sequence":"additional","affiliation":[{"name":"Magnetic Resonance Unit, National Institute of Cardiology, 04-628 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9619-2718","authenticated-orcid":false,"given":"Jan","family":"Henzel","sequence":"additional","affiliation":[{"name":"Department of Coronary and Structural Heart Diseases, National Institute of Cardiology, 04-628 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jacek","family":"Grzybowski","sequence":"additional","affiliation":[{"name":"Department of Cardiomyopathy, National Institute of Cardiology, 04-628 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marcin","family":"Demkow","sequence":"additional","affiliation":[{"name":"Department of Coronary and Structural Heart Diseases, National Institute of Cardiology, 04-628 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zofia","family":"Dzieli\u0144ska","sequence":"additional","affiliation":[{"name":"Department of Coronary and Structural Heart Diseases, National Institute of Cardiology, 04-628 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,9,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2645","DOI":"10.1016\/j.ajpath.2017.08.022","article-title":"Myofilament Remodeling and Function Is More Impaired in Peripartum Cardiomyopathy Compared with Dilated Cardiomyopathy and Ischemic Heart Disease","volume":"187","author":"Bollen","year":"2017","journal-title":"Am.
