Aim. The aim of the study was to evaluate the incidence and predictors of acute kidney injury (AKI) associated with transcatheter aortic valve implantation (TAVI).Material and methods. 50 patients (39 women, 11 men) aged 76 (71; 80) years who underwent TAVI were examined. One day after TAVI, blood creatinine level was determined by the Jaffe method and troponin I by a highly sensitive method (hs-cTnI). Acute kidney injury (AKI) was diagnosed according to the KDIGO criteria (2012). The following hospital complications were evaluated: cases of cardiac death, intraoperative myocardial infarction (MI), stroke and transient ischemic attack, permanent pacemaker implantation, recurrent paroxysms of atrial fibrillation.Results. History of MI had 22% of patients, percutaneous coronary intervention – 38%, hypertension – 98%, chronic kidney disease – 48%, diabetes mellitus – 24%, class II NYHA of chronic heart failure (CHF) – 52%, NYHA class III – 46%, NYHA class IV – 2%. The risk of operational mortality according to EuroSCORE II was 6.3±5.4%. AKI after TAVI was registered in 6 (12%) patients (1 grade AKI – 8%, 2 grade – 2%, 3 grade – 2%). Parameters associated with AKI after TAVI were higher CHF NYHA class (p=0,020), high hs-cTnI level (p=0,013), intraoperative MI (p=0.035). The predictor of AKI after TAVI was high hs-cTnI level (odds ratio 4.0, 95% confidence interval 1.0-16.1). Among patients with AKI after TAVI in compare with patients without AKI, the cumulative frequency of cardiac death, MI, strokes and transient ischemic attacks, implantation of a permanent pacemaker, the proportion of people with paroxysmal atrial fibrillation during the hospital stay was 5,8 times higher (66.7% vs 11.4% respectively, p=0.001).Conclusion. AKI after TAVI was present in 12% of patients. The predictor for AKI development was an increase in hs-cTnI level after TAVI implantation. The hospital prognosis after TAVI is worse in patients with postoperative AKI.
