Factors predicting outcomes after MitraClip implantation are not well defined. We aimed to report the influence of baseline renal function on short-term outcomes of patients enrolled in the investigator-initiated German transcatheter mitral valve interventions (TRAMI) registry. ⋯ Renal function at the time of interventional mitral valve repair with the MitraClip system is a strong predictor for procedural outcomes. Patients with severe renal impairment have a more than threefold increased risk for acute procedural failure, in-hospital death and 30-day mortality.
