Predictors and outcomes of heart failure after transcatheter aortic valve implantation using a self-expanding prosthesis

Abstract Introduction and objectives The purpose of this analysis was to assess the incidence, predictors and prognostic impact of acute heart failure (AHF) after transcatheter aortic valve implantation (TAVI) using a self-expanding prosthesis. Methods From November 2008 to June 2017, all consecutive patients undergoing TAVI in our center were prospectively included in our TAVI registry. The predictive effect of AHF on all-cause mortality following the TAVI procedure was analyzed using Cox regression models. Results A total of 399 patients underwent TAVI with a mean age of 82.4 ± 5.8 years, of which 213 (53.4%) were women. During follow-up (27.0 ± 24.1 months), 29.8% (n = 119) were admitted due to AHF, which represents a cumulative incidence function of 13.2% (95%CI, 11.1%-15.8%). At the end of follow-up, 150 patients (37.59%) had died. Those who developed AHF showed a significantly higher mortality rate (52.1% vs 31.4%; HR, 1.84; 95%; CI, 1.14-2.97; P = .012). Independent predictors of AHF after TAVI were a past history of heart failure (P = .019) and high Society of Thoracic Surgeons score (P = .004). We found that nutritional risk index and chronic obstructive pulmonary disease were strongly correlated with outcomes in the AHF group. Conclusions TAVI was associated with a high incidence of clinical AHF. Those who developed AHF had higher mortality. Pre-TAVI AHF and high Society of Thoracic Surgeons score were the only independent predictors of AHF in our cohort. A low nutritional risk index and chronic obstructive pulmonary disease were independent markers of mortality in the AHF group.
