Prospective Neuropsychological Evaluation of the Implementation of a Heart Valve Unit (HVU-NEURO)

Sponsor: Heart and Brain Research Group, Germany

Summary

Transcatheter aortic valve implantation (TAVI) is an established treatment for severe aortic stenosis. Despite improved procedural outcomes, neurocognitive complications such as postoperative delirium (POD) and postoperative cognitive decline (POCD) remain clinically relevant. Heart Valve Units (HVU) are specialized interdisciplinary care structures designed to improve treatment pathways and healthcare quality. However, their impact on neuropsychological outcomes has not been sufficiently investigated. HVU-NEURO is a prospective observational cohort study evaluating neuropsychological outcomes before and after implementation of an HVU. Approximately 500 patients undergoing transcatheter valve therapy will be included. Neurocognitive function will be assessed before intervention, at hospital discharge, and three months after intervention. POD will be assessed using the Intensive Care Delirium Screening Checklist (ICDSC). The primary objective is to evaluate the effect of HVU implementation on postoperative cognitive decline at discharge from acute hospital care.
