    AbstractSystemic inflammatory indices, originally developed to predict the prognosis of cancer patients, have found increasing application in various medical areas, including cardiovascular research. This study aimed to investigate the relationship between ascending aortic dilatation in bicuspid aortic valve patients and systemic inflammatory indices. This retrospective cross-sectional study included 122 patients with bicuspid aortic valves. These patients were divided into 2 groups based on the presence or absence of dilatation according to ascending aorta z-scores. Complete blood counts were analyzed, focusing on leukocyte, neutrophil, lymphocyte, monocyte, and platelet counts. Additionally, systemic inflammatory indices including neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio (PLR), Systemic Immune-Inflammation Index (SII), Systemic Inflammatory Response Index (SIRI), and monocyte-to-lymphocyte ratio (MLR) and pan-immune-inflammation value (PIV) were calculated from these parameters. MLR, SIRI, and PIV demonstrated acceptable diagnostic power in detecting ascending aortic dilatation in bicuspid aortic valve patients, with area under the curve (AUC) values of 0.709, 0.741, and 0.779, respectively. PLR and SII exhibited fair diagnostic power, with AUC values of 0.673 and 0.688, respectively. According to the receiver operating characteristic analysis, PIV had the highest AUC value of 0.779 (95% confidence interval [CI] = 0.69-0.86), with a sensitivity of 70.9% and specificity of 70.8% at a cutoff value of 224.93. A relationship exists between PLR, MLR, SII, SIRI, PIV, and ascending aorta dilatation in pediatric patients with bicuspid aortic valves. These findings suggest that inflammation may play a role in the dilatation of the ascending aorta in bicuspid aortic valve patients.Copyright © 2024 the Author(s).
