We reported a case of a 4-month-old infant with worsening breathlessness. While admitted, she was in severe respiratory distress and appeared drowsy. We also noted indiscernible heart sounds from physical examination and cardiomegaly with a globular cardiac silhouette from chest X-ray. Considering her distressing clinical presentation, we suspected cardiac tamponade and performed an emergent transthoracic echocardiography to confirm our suspicion. Echocardiogram, however, demonstrated only mild pericardial effusion\u2014insufficient to explain her symptoms. Moreover, we found exceedingly thick myocardium consistent with hypertrophic cardiomyopathy, so we initially focused our treatment strategy on congestion relief.<\/jats:p>","DOI":"10.1177\/2050313x261429629","type":"journal-article","created":{"date-parts":[[2026,3,11]],"date-time":"2026-03-11T13:15:05Z","timestamp":1773234905000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Infantile hypertrophic cardiomyopathy masquerading as cardiac tamponade: A case report"],"prefix":"10.1177","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9837-2843","authenticated-orcid":false,"given":"Theresia Sri Rezeki","family":"Sembiring","sequence":"first","affiliation":[{"name":"Department of Cardiology and Vascular Medicine, Komodo Regional District Hospital of Labuan Bajo, West Manggarai, Indonesia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-3001-5982","authenticated-orcid":false,"given":"Mochamad Faisal","family":"Adam","sequence":"additional","affiliation":[{"name":"Department of Cardiology and Vascular Medicine, Indramayu Regional District Hospital, Indonesia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2026,3,4]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1186\/s13052-021-01145-x"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.4070\/kcj.2021.0153"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.21037\/acs.2017.07.04"},{"key":"e_1_3_3_5_2","first-page":"340","volume-title":"Pathophysiology of heart disease: a collaborative project of medical students and faculty","author":"Lilly LS","year":"2016","unstructured":"Lilly LS.
