Neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) can risk stratify patients in transcatheter aortic-valve replacement (TAVR).

Background: Neutrophil-lymphocyte (NLR) and platelet-lymphocyte ratios (PLR) mark systemic inflammation. Patients with high NLR and PLR have worse cardiovascular disease and outcomes. We assessed the role of these ratios in predicting outcomes after transcatheter aortic valve replacement (TAVR).
