Brief Summary

Aortic valve stenosis is one of the most common types of heart disease in the aging Western population. While surgical cardiac valve replacement (SAVR) is a standard therapy for patients with aortic stenosis, catheter-assisted aortic valve implantation (TAVI) has developed as an alternative to open-heart surgery, especially for high-risk patients. Recently, increased surgeon experience and improved transcatheter valve systems have led to a global trend to use TAVI in patients with low or intermediate risk. Although cognitive impairment after cardiac surgery is well known, the effect of TAVI on cognitive function has not yet been adequately investigated. The aim of this study is to compare the occurrence and progression of delirium, postoperative cognitive decline (POCD), cerebral infarction, and health-related quality of life (QOL) in patients with intermediate risk for catheter-assisted (TAVI) and surgical (SAVR) aortic valve replacement.

Outcome Measures

Primary Outcomes (3)

  • Number of participants with postoperative cognitive decline at 3 months after surgery, defined as a decrease between pre- and postoperative examinations of one standard deviation in at least 20% of all objective neuropsychological parameters

    The objective neuropsychological parameters measure cognitive domains like immediate memory span, free recall, recognition memory, selective attention, working memory, inhibition and word fluency. These cognitive domains will be measured with the following instruments: "Verbaler Lern- und Merkfähigkeitstest" (VLMT), "Trail Making Test A/B" (TMT), "Letter Number Span Test" (LNS), Block Tapping Test (BTT), "Regensburger Wortflüssigkeits-Test" (RWT), and "Syndrom-Kurz Test" (SKT).

    Immediately pre-surgery to 3 months post-surgery

  • Number of participants with postoperative cognitive decline at the time of discharge from the acute clinic, defined as a decrease between the pre- and postoperative examinations of one standard deviation measured with the "Montreal Cognitive Assessment"

    The "Montreal Cognitive Assessment" (MOCA) is a screening procedure for general cognitive function.

    Immediately pre-surgery to approximately 1 week post-surgery

  • Number of participants with postoperative delirium during the stay in the intensive care unit as assessed by the "Intensive Care Delirium Screening Checklist" (ICDSC)

    Postoperative delirium is defined as the occurrence of at least one delirious episode during a stay in the intensive care unit. The "Intensive Care Delirium Screening Checklist" (ICDSC) record the clinical symptoms of consciousness, attention, orientation, hallucinations, psychomotor retardation or agitation, speech, and changing symptoms by observing behavior and asking concrete questions to the patient.

    Immediately post-surgery to approximately 7 days post-surgery

Secondary Outcomes (6)

  • Change from baseline cognitive failures in everyday life at 3 months after surgery as assessed by the "Cognitive Failures Questionnaire" (CFQ)

    Immediately pre-surgery to 3 months post-surgery

  • Change from baseline health-related quality of life at 3 months after surgery as assessed by the "36-Item Short Form Health Survey" (SF36)

    Immediately pre-surgery to 3 months post-surgery

  • Change from baseline anxiety at 3 months after surgery as assessed by the "Hospital Anxiety and Depression Scale" (HADS).

    Immediately pre-surgery to 3 months post-surgery

  • Change from baseline depression at 3 months after surgery as assessed by the "Hospital Anxiety and Depression Scale" (HADS).

    Immediately pre-surgery to 3 months post-surgery

  • Number of participants with postoperative acute ischemic lesions at the time of discharge from the acute clinic as assessed by magnetic resonance images (MRI).

    Once within the 6th-10th day immediately post-surgery

  • +1 more secondary outcomes

  • Previous heart surgery
  • Percutaneous coronary intervention performed within one month prior to the study
  • Hemodynamic instability requiring inotropic support or mechanical circulatory support
  • Ischemic stroke or intracranial bleeding within the month before the start of the study
  • Severe ventricular dysfunction with left ventricular ejection fraction \< 20% as measured by echocardiogram
  • Hypertrophic obstructive cardiomyopathy or severe basal septum hypertrophy
