Cerebral Protection in Transcatheter Left Atrial Appendage Occlusion

Status Recruiting

Clinical Trial Summary

The study aims to assess the effect of the use of neuroprotection in transcutaneous occlusion of the left atrial appendage in patients with atrial fibrillation on the risk of perioperative silent brain ischemia and associated cognitive impairment and depression.

Clinical Trial Description

Introduction: Left atrial appendage occlusion (LAAC) procedure is a method of preventing stroke in patients with atrial fibrillation who cannot use anticoagulants. The number of patients undergoing LAAC treatment tends to increase. LAAC procedures effectively reduce the number of strokes, with a significant reduction in the risk of bleeding compared to oral anticoagulants. However, although LAAC treatments alone have a low risk of perioperative stroke, some patients may experience incidents of silent brain ischemia (SBI). The distant effect of SBI may be cognitive deterioration, the onset of dementia syndromes, as well as depression. Purpose of the study: The study aims to assess the effect of the use of neuroprotection in transcutaneous occlusion of the left atrial appendage (LAAC) in patients with atrial fibrillation on the risk of perioperative SBI and associated cognitive impairment and depression. Methodology: The planned study is a prospective, multicentre, randomized, and double-blind intervention trial. Neuroprotection introduced from arterial access will be used in the LAAC treatment study group. In the control group, LAAC treatments will be performed without neuroprotection. Two hundred forty patients are planned to be enrolled with indications for stroke prevention due to atrial fibrillation. The analysis will include data obtained from DW MRI images, neurological evaluation results along with NIHSS-scale scores, results of cognitive evaluation tests (MoCA, COWAT, TMT A&B), and test of mood disorders (HADS Scale), as well as results of the EQ-5D-5L quality of life assessment questionnaire. It is planned to observe patients participating in the study for 24 months after LAAC procedure. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
