Predictors of In-Hospital Mortality after Transcatheter Aortic Valve Implantation

The development of aortic valve stenosis is strongly associated with older adults. Patients who undergo transcatheter aortic valve implantation (TAVI) for severe aortic stenosis (AS) frequently have heart failure (HF). We investigated the predictors of mortality after TAVI according to the presence of HF, and specifically HF with preserved ejection fraction (HFpEF) versus HF with reduced ejection fraction (HFrEF). Patients were identified from the Nationwide Inpatient Sample registry from January 2011 to September 2015  using the ICD-9 codes. Patients with HF who underwent TAVI were classified according to whether they were diagnosed with HFrEF or HFpEF.
