Stroke Clinical Trial
— INTERCEPTaviOfficial title:
INTERvention With Cerebral Embolic Protection in Transcatheter Aortic Valve Implantation (INTERCEPTavi): 'Carbon-Dioxide Flushing Versus Saline Flushing of Transcatheter Aortic Valves: A Single-centre Randomised Controlled Trial'
The study aims to evaluate the processes of a pilot single-centre randomised controlled trial (RCT) of carbon-dioxide flushing of transcatheter aortic valves (TAVI-CO2) versus standard saline flushing of valves (TAVI-S) and assess potential neuroprotection through a number of neurological endpoints for planning of a full-sized RCT

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Other | Detection of periprocedural cerebral solid and gaseous emboli | Document the overall rate of periprocedural cerebral solid and gaseous embolisation by transcranial doppler (TCD) monitoring during the TAVI procedure. | During TAVI procedure | |
Other | Neurological deficit | Patients will undergo neurological assessment pre TAVI (baseline), post TAVI as inpatient, at 6-weeks and 6-months following TAVI. | 6 Months | |
Other | Inflammatory biomarker assessing brain injury | Serial measurement of pro-inflammatory biomarkers pre-operatively, at the end of procedure and 24 hours post-operatively as a marker of brain damage including S100B | 24 hours post TAVI | |
Other | Neurocognitive decline | Patients will undergo neurocognitive assessment pre TAVI (baseline), post TAVI as inpatient, at 6-weeks and 6-months following TAVI. | 6 Months | |
Primary | Number of participants suitable for recruitment for larger RCT | Conduct an evaluation of the processes described in this pilot RCT for a full-scale RCT including:
Screening, Recruitment and Randomisation Retention in follow-up assessments Study design for a full RCT and identification of important stratification variables Refine sample size calculation for a full RCT |
Duration of study, approximately 15 months | |
Secondary | Incidence of Vascular Brain Injury (VBI) on Diffusion Weighted-Magnetic Resonance Imaging (DW-MRI) | Assessment of the incidence of DW-MRI detected VBI lesions following TAVI procedure. Patients will have MRI following their TAVI within 1-7 days and then at 6-months post TAVI. | Post TAVI 1-7 days and 6-months post TAVI |
