Cor triatriatum sinister is a rare anomaly (0.1% of all cases of congenital heart disease) that is seldom diagnosed in adult patients. The hallmark of this congenital defect is the presence of a fibromuscular membrane that divides the left atrium (LA) into two chambers: a postero-superior chamber into which the pulmonary veins drain and an infero-anterior chamber (true LA) containing the mitral valve and atrial appendage. Both chambers communicate through a membrane in which one or more drain holes can be found. When the hole is significantly obstructive, it results in increased venous and arterial pressures. Even though the definitive treatment of cor triatriatum is the surgical excision of the membrane, we present a balloon dilatation case with a good response to percutaneous therapy, both initially and in the ensuing months.<\/jats:p>","DOI":"10.1093\/eurjhf\/hfs164","type":"journal-article","created":{"date-parts":[[2012,10,29]],"date-time":"2012-10-29T09:57:15Z","timestamp":1351504635000},"page":"237-239","source":"Crossref","is-referenced-by-count":15,"title":["Unusual Case of New-Onset Heart Failure Due to Cor Triatriatum Sinister"],"prefix":"10.1093","volume":"15","author":[{"given":"Ana Bel\u00e9n","family":"M\u00e9ndez","sequence":"first","affiliation":[{"name":"Hospital de Sant Pau, Cardiology , Mas Casanovas, 90, Barcelona, 08041 ,","place":["Spain"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Teresa","family":"Colchero","sequence":"additional","affiliation":[{"name":"Hospital de Sant Pau, Cardiology , Mas Casanovas, 90, Barcelona, 08041 ,","place":["Spain"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joan","family":"Garcia-Picart","sequence":"additional","affiliation":[{"name":"Hospital de Sant Pau, Cardiology , Mas Casanovas, 90, Barcelona, 08041 ,","place":["Spain"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Montserrat","family":"Vila","sequence":"additional","affiliation":[{"name":"Hospital de Sant Pau, Cardiology , Mas Casanovas, 90, Barcelona, 08041 ,","place":["Spain"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria Teresa","family":"Subirana","sequence":"additional","affiliation":[{"name":"Hospital de Sant Pau, Cardiology , Mas Casanovas, 90, Barcelona, 08041 ,","place":["Spain"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alessandro","family":"Sionis","sequence":"additional","affiliation":[{"name":"Hospital de Sant Pau, Cardiology , Mas Casanovas, 90, Barcelona, 08041 ,","place":["Spain"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2014,1,27]]},"reference":[{"key":"2026011921140752000_ejhfhfs164-bib-0001","doi-asserted-by":"crossref","first-page":"1666","DOI":"10.1016\/j.athoracsur.2005.04.055","article-title":"Cor triatriatum: presentation, diagnosis and long-term results of surgical cor triatriatum","volume":"80","author":"Alphonso","year":"2005","journal-title":"Ann Thorac Surg"},{"key":"2026011921140752000_ejhfhfs164-bib-0002","doi-asserted-by":"crossref","first-page":"888","DOI":"10.1016\/S0002-8703(96)90328-2","article-title":"Percutaneous balloon dilatation of cor triatriatum sinister","volume":"132","author":"Kerkar","year":"1996","journal-title":"Am Heart J"},{"key":"2026011921140752000_ejhfhfs164-bib-0003","doi-asserted-by":"crossref","first-page":"e26","DOI":"10.1136\/heart.89.10.e26","article-title":"Cor triatriatum sinister in the adult presenting as mitral stenosis","volume":"89","author":"Slight","year":"2003","journal-title":"Heart"},{"key":"2026011921140752000_ejhfhfs164-bib-0004","doi-asserted-by":"crossref","first-page":"803","DOI":"10.1093\/eurjhf\/hfs105","article-title":"ESC Guidelines for the diagnosis and treatment of acute and chronic heart failure 2012: the Task Force for the Diagnosis and Treatment of Acute and Chronic Heart Failure 2012 of the European Society of Cardiology.
