Renal resistive index for risk stratification and functional evaluation after transcatheter mitral valve repair: the ReRISE study
A baseline RRI above 0.70 was independently associated with mortality following M-TEER, underscoring its potential prognostic relevance. The marked post-procedural decline in RRI, especially in patients with relevant MR improvement, suggests that RRI reflects hemodynamic rather than renal filtration changes. Given the limited sample size and number of events, these findings should be considered exploratory and hypothesis-generating, requiring validation in larger multicenter cohorts.
