About this study
Official title: Perioperative Intensive Statin Therapy for Neuroprotection in Transcatheter Aortic Valve Replacement
Transcatheter aortic valve replacement (TAVR) has become the most anticipated treatment method in the cardiovascular field in recent years, experiencing rapid development. However, neurological complications related to the surgery, such as ischemic injury, stroke, transient ischemic attack, and postoperative delirium, remain the main causes of increased postoperative mortality. Currently, there are limited measures for neuroprotection during the perioperative period of TAVR, and controversy continues over the effectiveness of intraoperative cerebral device placement. Consequently, strategies for neuroprotection during TAVR require active exploration. Previous studies have shown that statins have pleiotropic effects. In addition to inhibiting cholesterol synthesis, it also exhibits anti-inflammatory, antioxidant, stress-reducing, and platelet aggregation-inhibiting properties, as well as potential neuroprotective effects. The efficacy and safety of intensive statin therapy during the perioperative period of percutaneous coronary intervention have been extensively examined, and its role in improving long-term prognosis has been recognised. Since coronary heart disease and aortic valve stenosis share similar pathophysiological mechanisms, the use of statins in valve replacement surgery has also demonstrated positive effects. Research indicates that preoperative high-intensity statin therapy can reduce the incidence of stroke or transient ischemic attack following valve replacement surgery. Additionally, evidence suggests that preoperative statin use can decrease the occurrence of postoperative delirium. However, no evidence exists on whether perioperative intensive statin therapy during TAVR can reduce cerebral ischaemic injury and provide neuroprotection. This study aims to conduct a prospective, randomised, double-blind, multicentre clinical trial to evaluate the neuroprotective effects of statin-enhanced therapy during the perioperative period of TAVR and to investigate whether it can reduce cerebral ischaemic injury after TAVR.

The record says: opening soon, as of the sponsor's last update on 28 Jul 2025. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The number of new ischemic lesions on brain DW-MRI on the third day after TAVR (time frame: Day 3). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Jul 2025.
