The deceased was a 32-year-old man. At lunchtime his symptoms of unease, giddiness and unconsciousness began and within 45 minutes he arrived at the hospital. His vitals could not be recorded in the emergency department, and after CPR, he was pronounced dead. At autopsy, an isolated right atrial rupture, without any disease of the heart wall, was discovered. The right atrium has the weakest wall and is frequently the site of spontaneous rupture brought on by increased intraluminal pressure. Both liquid blood and clotted blood were found in the pericardial cavity. Low atrial pressure encourages clot formation because it causes considerably slower blood entry into the pericardium at the time of atrial rupture compared with entry at the time of ventricular rupture. Evidence of chronic lung disease was found which explains the raised intraluminal pressure of the heart chambers. Even with no history of trauma or myocardial infarction, the Beck triad \u2013 an engorged neck vein, a muffled heart sound, and low blood pressure \u2013 should alert the emergency room staff to the possibility of cardiac tamponade because, in a very unlikely scenario, spontaneous cardial wall rupture might occur.<\/jats:p>","DOI":"10.1177\/00258172231225915","type":"journal-article","created":{"date-parts":[[2024,4,15]],"date-time":"2024-04-15T08:05:50Z","timestamp":1713168350000},"page":"91-94","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Sudden death due to spontaneous rupture of the right atrium in the setting of chronic lung disease: A case report and review"],"prefix":"10.1177","volume":"93","author":[{"given":"Jitendra S","family":"Tomar","sequence":"first","affiliation":[{"name":"Department of Forensic Medicine &amp; Toxicology, MGM Medical College, Indore, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9120-1569","authenticated-orcid":false,"given":"Bajrang K","family":"Singh","sequence":"additional","affiliation":[{"name":"Department of Forensic Medicine &amp; Toxicology, MGM Medical College, Indore, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Surya","family":"Prakash","sequence":"additional","affiliation":[{"name":"Department of Forensic Medicine &amp; Toxicology, MGM Medical College, Indore, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pramendra S","family":"Thakur","sequence":"additional","affiliation":[{"name":"Department of Forensic Medicine &amp; Toxicology, MGM Medical College, Indore, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2024,4,15]]},"reference":[{"key":"e_1_3_9_2_2","first-page":"12","article-title":"Case of rupture of the right auricle of the heart","volume":"1","author":"Rutherfoord R.","year":"1828","unstructured":"Rutherfoord R.
