Background and Aims: Determining the severity of mitral stenosis (MS) is important for both prognostic andtherapeutic reasons. Measurement of Mitral valve area (MVA) by planimetry is gold standard and accurate but is highlyoperator dependent. Pressure Half Time (PHT) is affected by hemodynamic significance. In this Study we evaluated severityof mitral stenosis by mitral leaflet separation index (MLS index, MLSI). This new index could be useful surrogate measureof the MVA. Methods: This is a hospital based, cross-sectional observational study carried out in Shahid Gangalal National HeartCentre (SGNHC), Kathmandu, Nepal. Study included 82 patients with Rheumatic MS who had undergone echocardiographicexamination from July 2018 to December 2018. The maximal separation of the mitral valve leaflet tips was measured frominner edge to inner edge in end diastole in the parasternal long axis and apical 4-chamber views. These two parameters wereaveraged to yield the MLSI. The index was compared with mitral valve area determined by planimetry method and PHT. Results: Of the 82 study subjects, majority were females 72 (85.4%). The mean age of study patients was 37.33±11.56years. 30.5% had mild MS by planimetry, 31.7% had moderate MS and 37.8% had severe MS. There was a very strongcorrelation between MLS index and MVA by planimetry ( r = 0.89, p<0.001) and MVA by PHT (r=0.95, p<0.001). MLSindex less than 0.73 cm can predict severe MS with 93.2% sensitivity and 89.3% specificity. On the other hand MLS indexmore than 1.035cm can predict mild MS with 70% sensitivity and 89.3% specificity. Strong correlation exists between MLSindex and MV severity in presence atrial fibrillation (AF) (r=0.879) for planimetry and (r=0.835) for PHT and in presence ofcoexisting mitral regurgitation (MR) (r=0.89) for planimetry and (r=0.86) for PHT. Conclusion: MLSI has a strong correlation with MVA by planimetry and PHT. So, it can be used as a reliable method toassess severity of mitral stenosis and is a simple and easily obtainable.
