The mitral valve area (MVA) can be measured by planimetry, pressure half-time, continuity equation, and proximal isovelocity surface area methods. In this study, we propose a novel yet simple, independent measure of MS severity\u2013the mitral leaflet separation (MLS) index. This new index could be a useful surrogate measure of the MVA.  This index would also help when there is a discrepancy between severities of MS estimated by existing methods, in the presence of atrial fibrillation and in the presence of mitral regurgitation.<\/jats:p>","DOI":"10.5402\/2011\/768097","type":"journal-article","created":{"date-parts":[[2011,5,19]],"date-time":"2011-05-19T19:34:07Z","timestamp":1305833647000},"page":"1-4","source":"Crossref","is-referenced-by-count":8,"title":["Mitral Leaflet Separation Index in Assessing the Severity of  Mitral Stenosis"],"prefix":"10.5402","volume":"2011","author":[{"given":"Joby K.","family":"Thomas","sequence":"first","affiliation":[{"name":"Department of Cardiology, Kottayam Medical College, Kerala 686008, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"T.
