Recurrent attacks of rheumatic fever can lead to mitral stenosis. In a country like India mitral stenosis can develop in the first decade of life. Our patient presented with recurrent mitral stenosis at twelve years of age. He had undergone balloon mitral valvotomy at the age of seven. However this time he developed anterior mitral valve leaflet tear after balloon mitral valvotomy and had to be taken for mitral valve repair. Due to severe fibrosis of mitral valve the patient underwent mitral valve replacement. He was started on warfarin and dose titrated according to PT / INR. Patient was discharged but has to be on lifelong anticoagulation from the age of twelve.

Surgical System

Reports of mitral valve replacement after MitraClip removal have increased; however, surgical re-intervention is risky due to patients’ frailty and comorbidities. We report a case of mitral valve repair after MitraClip failure using the daVinci surgical system for a 55-year-old man with many comorbidities and two previous cardiac surgeries. The daVinci surgical system allows detailed handling with high-resolution visualization and endowrist instruments that provide surgeons with clear three-dimensional images and stabilized handling. This procedure enables us to remove the MitraClip precisely while preserving the mitral valve leaflet.

Infective native mitral valve endocarditis occurs rarely. Mitral valve repair, although surgically challenging, is favored over replacement in the latest European and American guidelines. In this video tutorial, patch repair of the posterior mitral valve leaflet is performed in a 61-year-old patient with endocarditis caused by Streptococcus agalactiae.

Background and Aims: Determining the severity of mitral stenosis (MS) is important for both prognostic and therapeutic reasons. Measurement of Mitral valve area (MVA) by planimetry is gold standard and accurate but is highly operator dependent. Pressure Half Time (PHT) is affected by hemodynamic significance. In this Study we evaluated severity of mitral stenosis by mitral leaflet separation index (MLS index, MLSI). This new index could be useful surrogate measure of the MVA. Methods: This is a hospital based, cross-sectional observational study carried out in Shahid Gangalal National Heart Centre (SGNHC), Kathmandu, Nepal. Study included 82 patients with Rheumatic MS who had undergone echocardiographic examination from July 2018 to December 2018. The maximal separation of the mitral valve leaflet tips was measured from inner edge to inner edge in end diastole in the parasternal long axis and apical 4-chamber views. These two parameters were averaged 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±11.56 years. 30.5% had mild MS by planimetry, 31.7% had moderate MS and 37.8% had severe MS. There was a very strong correlation between MLS index and MVA by planimetry ( r = 0.89, p<0.001) and MVA by PHT (r=0.95, p<0.001). MLS index less than 0.73 cm can predict severe MS with 93.2% sensitivity and 89.3% specificity. On the other hand MLS index more than 1.035cm can predict mild MS with 70% sensitivity and 89.3% specificity. Strong correlation exists between MLS index and MV severity in presence atrial fibrillation (AF) (r=0.879) for planimetry and (r=0.835) for PHT and in presence of coexisting 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 to assess severity of mitral stenosis and is a simple and easily obtainable. It has good correlation even in presence of AF and MR.
