Inflammatory biomarker kinetics after mechanical and bioprosthetic valve replacement.

Introduction: valve disease is an important cause of heart failure. There is a direct relationship between valve deterioration and the patient's inflammatory status and cytokines: interleukin-6, interleukin-1, tumor necrosis factor, and C-reactive protein, involved in this major state of inflammation.

Objective: to report a series of cases of valve replacement, using a bioprosthetic or mechanical valve, and the inflammatory profile of them.
