Abstract Patients with advanced chronic renal dysfunction were excluded from randomized trials of transcatheter aortic valve replacement (TAVR). The potential impact of chronic renal disease on TAVR prognosis is not fully understood. We aim to evaluate outcomes within a large cohort of patients undergoing TAVR distinguished by renal function. Baseline characteristics, procedural data and clinical follow-up findings were collected from 10 high-volume TAVR centers in Europe, Israel and Japan. Data was analyzed according to renal function. Patients (n=1204) were divided into 4 groups according to pre-TAVR estimated glomerular filtration rate (eGFR): group I (eGFR >60) n=288 (female 45%), group II (eGFR 31-60) n=452 (female 61%), group III (eGFR ≤30) n=398 (female 61%) and group IV (dialysis) n=66 (female 31%). Mean Society of Thoracic Surgeons (STS) score was higher in patients with lower pre-procedural eGFR. All-cause mortality at 1-year was higher in patients with lower eGFR (9.0%, 12.1%, 24.3%, 24.2% for group I, II, III and IV; respectively, p <0.001). Multivariate analysis demonstrated that eGFR ≤30, but not eGFR 31-60, was associated with increased risk of death (OR 3), bleeding (OR 5.2) and device implantation failure (HR 2.28). For each 10-mL/min decrease in eGFR, there was an associated relative increase in the risk of death (35%; p<0.001), cardiovascular death (14%; p=0.018), major bleeding 35% (p<0.001), and transcatheter valve failure (16%; p=0.007). Renal dysfunction was not associated with stroke or need for pacemaker implantation. In conclusion among patients undergoing TAVR, baseline renal dysfunction is an important independent predictor of morbidity and mortality.
