Association of preoperative systemic inflammation with postoperative conduction block in TAVI patients.

ABSTRACT:

Background

Conduction block (CB) is a frequent complication following transcatheter aortic valve implantation (TAVI). Systemic inflammation may play a role in its development, but evidence is limited.

Methods

This prospective study included 155 patients who underwent TAVI. Preoperative systemic inflammation markers-including systemic immune-inflammation index (SII), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and lymphocyte-to-monocyte ratio (LMR)-were analyzed in relation to postoperative conduction block and cardiac function using logistic and linear regression models, as well as restricted cubic spline analysis.

Results

Postoperative conduction block occurred in 35.5% of patients. Higher preoperative SII (OR = 1.0009; P = 0.0289
