Better methods of risk stratification are needed in this population with high morbidity. There is a relatively high incidence of cardiac amyloidosis in this population and high LV mass index (LVMI) to QRS voltage may help identify patients with worse prognosis following TAVI. This retrospective study enrolled consecutive patients who underwent TAVI in our institution between the years 2008\u20132019. Mass voltage ratio index (MVRi) was calculated as the ratio of LV mass index on echocardiogram to voltage using the Sokolow\u2010Lyon criteria on 12 lead ECG performed within 3 months before the intervention. Two hundred and fifty\u2010one patients (mean age 80.8 years, 49% men) were enrolled. One hundred and sixty\u2010eight (67%) patients were alive at 3 years follow up. MVRi was a statistically significant predictor of 3 year mortality (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.005). Patients were divided categorically into tertiles based on MVRi score; the \u201chigh\u201d group had significantly higher 3\u2010year mortality (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001). In the multivariate model only Euroscore (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.009) and MVRi (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.011; OR: 2.32; CI: 1.15\u20134.964) were statistically significant predictors of mortality. The \u201chigh\u201d group had a significantly lower survival rate after 3 years follow up on Kaplan\u2013Meier analysis (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001). Our findings suggest that MVRi is a strong, independent predictor of increased post\u2010TAVI mortality. This may be a simple clinical tool to assist in the assessment of patients prior to before TAVI.<\/jats:p><\/jats:sec>","DOI":"10.1002\/ccd.30117","type":"journal-article","created":{"date-parts":[[2022,2,3]],"date-time":"2022-02-03T20:36:11Z","timestamp":1643920571000},"page":"1918-1924","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Mass
