Defining this relationship in greater detail can potentially provide insight into device selection and patient-specific treatment goals. We therefore sought to better understand the relationship between both baseline TR severity and change in TR after TTVI and the extent of improvement in health status after TTVI.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>METHODS:<\/jats:title>\n                    <jats:p>As part of the Tri-QOL (Kansas City Cardiomyopathy Questionnaire Validation in Tricuspid Valve Disease) study, data from 11 studies of TTVI devices were transferred to the US Food and Drug Administration to harmonize and anonymize before analysis by an independent center. This secondary, observational analysis used patient-level data from the 6 single-arm studies of patients who underwent TTVI to explore the association of change in KCCQ-OS with TR grade using multivariable models, adjusted for age, sex, chronic lung disease, and baseline KCCQ-OS. The primary model included TR grade at baseline, TR grade at 1 month, and the interaction between the two.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS:<\/jats:title>\n                    <jats:p>Among 1056 patients with \u2265severe TR who underwent TTVI, mean age was 79.1\u00b17.1 years, 60.3% were female, and mean baseline Kansas City Cardiomyopathy Questionnaire-overall summary score [KCCQ-OS] was 49.5\u00b122.3. Baseline TR grade was severe in 33.5%, massive in 35.9%, and torrential in 30.6%. One-month after TTVI, TR was none\/trace in 21.7%, mild in 27.2%, moderate in 28.1%, and \u2265evere in 23.1%, while the mean change in KCCQ-OS was 17.0\u00b121.3 points. In a multivariable model that included TR grade at baseline, TR grade at 1 month, and their interaction, there was a strong association between reduction in TR and improvement in KCCQ-OS, with no consistent evidence of a threshold of TR grade below which there was no further improvement in KCCQ-OS. However, among patients with baseline torrential TR, the extent of health status improvement plateaued for patients achieving moderate or less TR at 1 month (ie, a 3-grade improvement from baseline).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSIONS:<\/jats:title>\n                    <jats:p>Health status improvement after TTVI was most strongly associated with the degree of TR reduction, although there was minimal additional improvement for most patients beyond a 3-grade reduction in TR. These findings support the goal of achieving mild or less TR with TTVI, although patients with torrential TR at baseline may be well served if moderate TR can be achieved.<\/jats:p>\n
