Prognosis of Prolonged Intensive Care Unit Stay After Aortic Valve Replacement for Severe Aortic Stenosis in Octogenarians

Aortic stenosis (AS) is the most frequent heart valve disease in octogenarians, and aortic valve replacement (AVR) remains the primary treatment for AS. This observational study conducted in the postoperative surgical intensive care unit (ICU) of a tertiary care facility in Paris, France, aimed to evaluate the mortality rate of octogenarians experiencing prolonged hospitalization in the ICU following cardiac surgery and to define the best cutoff for prolonged ICU length of stay (LOS). The secondary objective was to determine the risk factors associated with prolonged ICU LOS. For the purposes of this study, prolonged ICU
