Abstract

Background: The incidence of and risk factors for readmission for heart failure after successful transcatheter aortic valve implantation (TAVI) are unclear.

Aims: We sought to evaluate the incidence of, risk factors for and clinical impact of readmission for heart failure after successful TAVI in an unselected patient population.

Methods: All patients who underwent successful TAVI in two high-volume French tertiary centres from February 2010 to December 2016 were included prospectively and followed up for 1 year. A Cox multivariable model was used to assess risk factors for readmission for heart failure and mortality.

Results: A total of 1139 patients (mean age 82.4±7.7years; 52.2% male sex) were included. Readmission for heart failure occurred in 99 (9.2%) patients. Risk factors for readmission for heart failure were previous atrial fibrillation (adjusted hazard ratio [adjHR] 1.62, 95% confidence interval [CI] 1.09-2.40), diabetes mellitus (adjHR 1.67, 95% CI 1.11-2.50), chronic kidney disease (adjHR 1.72, 95% CI 1.13-2.62), chronic pulmonary disease (adjHR 1.81, 95% CI 1.17-2.81) and left ventricular ejection fraction after TAVI ≤ 35% (adjHR 2.12, 95% CI 1.20-3.75). Readmission for heart failure was strongly associated with mortality (adjHR 3.11, 95% CI 1.95-4.94), along with increased Society of Thoracic Surgeons' score (adjHR 1.07, 95% CI 1.03-1.12), chronic pulmonary disease (adjHR 1.45, 95% CI 1.00-2.09), previous atrial fibrillation (adjHR 2.11, 95% CI 1.52-2.93) and shock during the index hospitalization (adjHR 2.56, 95% CI 1.41-4.65).

Conclusions: Readmission for heart failure occurs in one in 10 patients after successful TAVI, and is a strong risk factor for mortality. Co-morbidities and left ventricular ejection fraction after TAVI≤35% are the main risk factors for readmission for heart failure.
