Predictors of One-Year Mortality After Transcatheter Aortic Valve Implantation for Severe Symptomatic Aortic Stenosis

Transcatheter aortic valve implantation (TAVI) is already an accepted option to treat elderly patients with severe symptomatic aortic stenosis who are inoperable or at high surgical risk. However, short- and long-term mortality after TAVI remains an important issue, raising the need to further improve the technology of TAVI as well as to identify patients who will not benefit from TAVI. A total of 1,391 patients treated with TAVI at 27 hospitals were included in the German Transcatheter Aortic Valve Interventions – Registry. One-year follow-up data were available for 1,318 patients (94.8%), with a mean follow-up period of 12.9 ± 4.5 months. One-year mortality was 19.9%. Survivors and nonsurvivors showed multiple differences in patient characteristics, indications for interventions, preintervention and interventional characteristics, and postintervention events. A higher logistic European System for Cardiac Operative Risk Evaluation score was associated with higher 1-year mortality (p
