Percutaneous Valve Replacement

Leon MB et al. Transcatheter aortic-valve implantation for aortic stenosis in patients who cannot undergo surgery. N Engl J Med. 2010 Oct 21;363(17):1597-607 [PMID 20961243]

  • 30% of patients with AS can’t under go surgery c/o co-morbidity
  • TAVI developed, first performed in 2002
  • 1 year mortality about 25% (without surgery mortality 50% after 2 years once symptomatic)

PARTNER Trial – Placement of Aortic Transcatheter Valves

  • MRCT
  • TAVI vs standard therapy in high-risk patients with severe AS
  • n = 358 (179 standard medical therapy vs 179 TAVI)
  • TAVI: high initial complication rate (bleeding, neurological events, vascular problems) and death rate -> death at 1 year: TAVI 31% vs 50% for medical therapy -> decreased repeat hospitalisation rates -> reduced symptoms
  • Weaknesses -> funded by Edwards Life Sciences -> 9 of the 22 authors had financial links to EL -> exclusion of important subgroups -> significant learning curve for operators
