Late kidney injury after transcatheter aortic valve replacement

Y Adachi, M Yamamoto, OCEAN-TAVI investigators et al. Keywords: late kidney injury; TAVR; clinical outcome

ABSTRACT

BACKGROUND - Information on early to late-phase kidney damage in patients who underwent transcatheter aortic valve replacement (TAVR) is scarce. We aimed to identify the predictive factors for late kidney injury (LKI) at 1-year and patient prognosis beyond 1-year after TAVR.

 

METHODS - We retrospectively reviewed 1705 patientsdata from the Japanese TAVR multicenter registry. Acute kidney injury (AKI) and LKI, defined as an increase of at least 0.3 mg/dl in creatinine level, a relative 50% decrease in kidney function from baseline to 48-hours and 1-year, were evaluated. The patients were categorized into the four groups as AKI- /LKI- (n=1362), AKI+ /LKI- (n=95), AKI- /LKI+ (n=199), and AKI+ /LKI+ (n=46).

 

RESULTS - The cumulative 3-year mortality rates were significantly increased across the four groups (12.5%, 15.8%, 24.6%, 25.8%, p<0.001). Multivariate analysis revealed that chronic kidney disease, coronary artery disease, peri-procedural AKI, and heart failure-related re-admission within 1-year were significantly associated with LKI. The Cox regression analysis revealed that AKI- /LKI+ and AKI+ /LKI+ were independent predictors of increased late mortality beyond 1-year after TAVR (p=0.001 and p=0.01).

 

CONCLUSION - LKI was influenced by adverse cardio-renal events and was associated with increased risks of late mortality beyond 1-year after TAVR.
