This retrospective analysis of the BTT continuous flow (CF) LVAD experience from Harefield Hospital addresses the question: "What are the predictors of the requirement for an RVAD at the time of LVAD implantation?" Of the 152 patients included in the study, 23% underwent RVAD implantation. Of all the univariate predictors of the requirement of an RVAD, the two significant independent variables on multivariate analysis were the preop TAPSE (tricuspid annular plane systolic excursion) and the left atrial diameter. Of note, a TAPSE value of <12.5 mm had an 84% sensitivity and 75% specificity for predicting the requirement for an RVAD.
