Thoracic radiographs showed pulmonary edema and pleural effusion. Echocardiography revealed a perforate membrane immediately above the mitral valve that divided the left atrium into proximal and distal chambers. The left auricle was proximal to the dividing membrane and connected to the markedly enlarged proximal left atrial chamber, consistent with the diagnosis of supravalvular mitral stenosis (SMS). Position of the obstructing membrane relative to the left auricle distinguishes SMS from cor triatriatum sinister (CTS). In CTS, the left auricle is distal to the dividing membrane and connects to the distal left atrial chamber.<\/jats:p>","DOI":"10.5326\/0380403","type":"journal-article","created":{"date-parts":[[2014,9,15]],"date-time":"2014-09-15T12:23:20Z","timestamp":1410783800000},"page":"403-406","source":"Crossref","is-referenced-by-count":18,"title":["Supravalvular Mitral Stenosis in a Cat"],"prefix":"10.5326","volume":"38","author":[{"given":"Deborah M.","family":"Fine","sequence":"first","affiliation":[{"name":"Department of Small Animal Clinical Sciences, College of Veterinary Medicine, University of Minnesota, 1365 Gortner Avenue, St. Paul, Minnesota 55108"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anthony H.","family":"Tobias","sequence":"additional","affiliation":[{"name":"Department of Small Animal Clinical Sciences, College of Veterinary Medicine, University of Minnesota, 1365 Gortner Avenue, St. Paul, Minnesota 55108"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kristin A.","family":"Jacob","sequence":"additional","affiliation":[{"name":"Department of Small Animal Clinical Sciences, College of Veterinary Medicine, University of Minnesota, 1365 Gortner Avenue, St. Paul, Minnesota 55108"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"3280","reference":[{"key":"R1","series-title":"J Am Vet Med Assoc","first-page":"49","volume":"188","year":"1986","unstructured":"Fossum TW, Jacobs RM, Birchard SJ.
