Structured PICO

Does transapical aortic valve implantation cause cerebral microembolism detectable by transcranial Doppler in high-risk patients?

P
Population
50 very high-risk patients undergoing transapical aortic valve implantation (TAVI), mean age 80 ± 5 years, mean EuroSCORE 36 ± 13%.
I
Intervention
Transapical aortic valve implantation (TAVI) with intraoperative transcranial Doppler (TCD) monitoring of both middle cerebral arteries
O
Outcome
Detection of high-intensity transient signals (HITS) and microembolic signals (MES) in the middle cerebral artery during seven phases of the proceduresurrogate

While cerebral microemboli are universally detected by transcranial Doppler during TAVI, particularly during balloon valvuloplasty and valve delivery, they did not result in apparent early clinical neurological events in this cohort.
