Summary Patient selection - shift towards lower risk, better functional class Procedural technique less invasive Long term mortality - ~1/2 within 5 years, mostly due to non-cardiac causes Hemodynamic & functional improvement - sustained for up to 5 years PVL - Incidence decreasing, new generation valves perform better TAVI in Rabin Medical Center -
