Left ventricular pulsus alternans is known to occur with ischemic heart disease, valvular heart disease, and outflow tract obstructions. Isolated right ventricular (RV) pulsus alternans is a rare entity. We report the case of a 51-year-old male patient who presented with inferior wall myocardial infarction and cardiogenic shock. He was diagnosed to have an isolated tricuspid regurgitation alternans signifying severe RV dysfunction. The patient was resuscitated and treated with primary percutaneous intervention to the right coronary artery. We also review the literature associated with RV pulsus alternans and its mechanisms.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.4103\/jcecho.jcecho_46_21","type":"journal-article","created":{"date-parts":[[2024,6,3]],"date-time":"2024-06-03T04:31:10Z","timestamp":1717389070000},"page":"54-56","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":0,"title":["Isolated Tricuspid Regurgitation Alternans in Acute Myocardial Infarction"],"prefix":"10.4103","volume":"32","author":[{"given":"Rakesh","family":"Agarwal","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"R2-10-20240904","doi-asserted-by":"crossref","first-page":"162","DOI":"10.12998\/wjcc.v1.i5.162","article-title":"Biventricular pulsus alternans: An echocardiographic finding in patient with pulmonary embolism","volume":"1","author":"Nguyen","year":"2013","journal-title":"World J Clin Cases"},{"key":"R3-10-20240904","doi-asserted-by":"crossref","first-page":"115","DOI":"10.1378\/chest.77.1.115","article-title":"Isolated right ventricular mechanical alternans in right ventricular infarction","volume":"77","author":"Bansal","year":"1980","journal-title":"Chest"},{"key":"R4-10-20240904","doi-asserted-by":"crossref","first-page":"163","DOI":"10.1161\/01.CIR.14.2.163","article-title":"Cardiocirculatory studies in pulsus alternans of the systemic and pulmonary circulations","volume":"14","author":"Cournand","year":"1956","journal-title":"Circulation"},{"key":"R6-10-20240904","doi-asserted-by":"crossref","first-page":"469","DOI":"10.1097\/HCO.0000000000000315","article-title":"Right heart imaging in patients with heart failure: A tale of two ventricles","volume":"31","author":"Amsallem","year":"2016","journal-title":"Curr Opin Cardiol"}],"container-title":["Journal of Cardiovascular Echography"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.ovid.com\/10.4103\/jcecho.jcecho_46_21","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,8,18]],"date-time":"2026-08-18T15:31:35Z","timestamp":1787067095000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ovid.com\/10.4103\/jcecho.jcecho_46_21"}},"subtitle":["A Rare Entity"],"short-title":[],"issued":{"date-parts":[[2022,1]]},"references-count":4,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2022]]}},"URL":"https:\/\/doi.org\/10.4103\/jcecho.jcecho_46_21","relation":{},"ISSN":["2211-4122"],"issn-type":[{"value":"2211-4122","type":"print"}],"subject":[],"published":{"date-parts":[[2022,1]]}}}
