Transcatheter or Surgical Treatment of Patients With Aortic Stenosis at Low to Intermediate Risk: An Individual Participant Data Meta-Analysis
Authors' conclusion
In this IPD meta-analysis of 4 RCTs, and an overall meta-analysis of 8 RCTs of patients with severe symptomatic AS at low to intermediate risk, TAVI was associated with a reduction in the 1-year incidence of all-cause death or any stroke.
