Aortic Stenosis: The Facts…

Untreated Aortic Stenosis has a poor natural history

Many patients are not referred for investigation or treatment

Excellent results for surgical AVR

Superior TAVI results vs. OMT for inoperable patients

Long-term TAVI leaflet durability unknown

Role of TAVI for surgically suitable patients uncertain
