Predictors of 1-year mortality after transcatheter aortic valve replacement.

Patient characteristics and procedure-related complications are both significantly associated with increased risk of death within 1 year of TAVR. Patients with the baseline findings of severe chronic lung disease or severe tricuspid valve regurgitation may not experience mortality benefit from TAVR, and they should be assessed and counselled accordingly. Avoiding procedure-related complications is paramount to a good outcome. The findings have important implications for health care delivery services.
