Patients were dichotomized according to the severity of pre\u2010TAVI TR: less than moderate versus moderate or greater. Logistic regression was used to determine the risk factors for progression or persistence of moderate or greater TR at 1 year after TAVI.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec id=\"jah311083-sec-0003\" xml:lang=\"en\">\n            <jats:title>Results<\/jats:title>\n            <jats:p xml:lang=\"en\">A total of 2250 patients were included for analysis, of which 301 (13.4%) had moderate or greater TR before TAVI. Baseline moderate or greater TR was associated with reduced survival and a higher incidence of heart failure readmission at 5\u2009years after TAVI. Twelve percent of patients had progression or persistence of moderate or greater TR at 1 year after TAVI. On multivariable logistic regression, increasing age, female sex, lower mean pre\u2010TAVI aortic transvalvular pressure gradient, pulmonary artery systolic pressure \u226540\u2009mm\u2009Hg, pulmonary vascular disease, and transfemoral vascular access were associated with progression or persistence of moderate or greater TR at 1 year after TAVI, while periprocedural variables related to valve implantation were not.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec id=\"jah311083-sec-0004\" xml:lang=\"en\">\n            <jats:title>Conclusions<\/jats:title>\n            <jats:p xml:lang=\"en\">Significant TR before TAVI was associated with poor outcomes after TAVI. The incidence of moderate or greater TR at 1 year after TAVI was reasonable at 12%. Periprocedural factors, such as valve size, type of implanted valve, and paravalvular leak, were not associated with the development of TR. Evolution of TR and heart failure symptoms must be carefully surveilled after TAVI.<\/jats:p>\n
