Late adverse cerebrovascular events follow 5% of TAVRs
Disabling ischaemic stroke more than 30 days post-procedure occurs most frequently, find researchers
More than 30 days after transcatheter aortic-valve replacement (TAVR), 5% of patients experience stroke or TIA, with most of the strokes being disabling, a study shows.
Researchers studied 3750 patients in centres in Canada, France and Spain with a mean age of 80 who underwent TAVR and survived beyond 30 days.
After a median follow-up of just over two years, 5% had a cerebrovascular event with 80% of the events being a stroke (mostly ischaemic) and 20% being a TIA.
The stroke was disabling in 70% of patients and associated with an in-hospital mortality rate of 29%, the authors reported in JACC: Cardiovascular Interventions.
