On evaluation, he was found to have a cystic mass in the left ventricle with severe left ventricular systolic dysfunction. A cardiac MRI revealed a multiloculated mass in the left ventricle with multiple septa with internal enhancement and CT coronary angiography revealed compression of a coronary artery by the cystic mass. Serological tests for hydatid came out strongly positive, and subsequently, he underwent surgical excision under cardiopulmonary bypass. Postoperatively, he is doing well with no complaints.<\/jats:p>","DOI":"10.1136\/bcr-2024-262559","type":"journal-article","created":{"date-parts":[[2025,1,14]],"date-time":"2025-01-14T07:00:50Z","timestamp":1736838050000},"page":"e262559","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Rare cause of angina: mechanical compression from hydatid cyst"],"prefix":"10.1136","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1136-6353","authenticated-orcid":false,"given":"Devesh","family":"Kumar","sequence":"first","affiliation":[{"name":"Cardiology, AIIMS New Delhi, New Delhi, Delhi, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Prerna","family":"Garg","sequence":"additional","affiliation":[{"name":"Medicine, AIIMS, New Delhi, Delhi, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9345-0232","authenticated-orcid":false,"given":"Kartik","family":"Aggarwal","sequence":"additional","affiliation":[{"name":"General Medicine, AIIMS, Ansari Nagar, New Delhi, Delhi, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rakesh","family":"Yadav","sequence":"additional","affiliation":[{"name":"Department of Cardiology, All India Institute of Medical Sciences Cardio-Thoracic Sciences Centre, New Delhi, Delhi, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2025,1,14]]},"reference":[{"key":"2025082711023188000_18.1.e262559.1","doi-asserted-by":"publisher","DOI":"10.3748\/wjg.v18.i13.1425"},{"key":"2025082711023188000_18.1.e262559.2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijid.2008.03.037"},{"key":"2025082711023188000_18.1.e262559.3","doi-asserted-by":"publisher","DOI":"10.1128\/CMR.17.1.107-135.2004"},{"key":"2025082711023188000_18.1.e262559.4","doi-asserted-by":"crossref","DOI":"10.1186\/s12917-018-1529-6","article-title":"Multiple zoonotic helminth infections in domestic dogs in a rural area of Khuzestan Province in Iran","volume":"14","author":"Beiromvand","year":"2018","journal-title":"BMC Vet Res"},{"key":"2025082711023188000_18.1.e262559.5","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(03)14573-4"},{"key":"2025082711023188000_18.1.e262559.6","doi-asserted-by":"crossref","first-page":"447","DOI":"10.4103\/2141-9248.133476","article-title":"Uncommon locations and presentations of hydatid cyst","volume":"4","author":"Sachar","year":"2014","journal-title":"Ann Med Health Sci Res"},{"key":"2025082711023188000_18.1.e262559.7","doi-asserted-by":"crossref","first-page":"120","DOI":"10.1016\/j.ijid.2019.09.004","article-title":"Cardiac hydatid cyst in the interventricular septum: A literature review","volume":"88","author":"Fennira","year":"2019","journal-title":"Int J Infect Dis"},{"key":"2025082711023188000_18.1.e262559.8","doi-asserted-by":"publisher","DOI":"10.1016\/S0828-282X(06)70254-9"},{"key":"2025082711023188000_18.1.e262559.9","doi-asserted-by":"crossref","DOI":"10.1186\/s43044-020-00085-x","article-title":"Primary cardiac hydatid cyst presenting with massive pericardial effusion: a case report","volume":"72","author":"El Boussaadani","year":"2020","journal-title":"Egypt Heart J"},{"key":"2025082711023188000_18.1.e262559.10","first-page":"1857","article-title":"Hydatid cyst of the interventricular septum.
