Risk factors for acute kidney injury following transcatheter aortic valve replacement: a systematic review and meta-analysis

Post-TAVR AKI is chiefly driven by cardiovascular comorbidity and renal impairment, with hypertension, coronary and peripheral vascular disease, prior stroke, CKD, elevated creatinine, high STS score, and transapical access displaying the strongest, independent associations. Awareness of these factors may facilitate peri-procedural risk stratification and targeted renal-protective strategies.
