Members of a clan can recognise each other by their smell. The badger has a special opening (called the subcaudal gland) under its tail, which produces a smelly liquid called musk. This musk is a soapy cream-coloured fatty substance (a bit like margarine in colour and texture).
The total average cost of the TAVI procedure was â¬ 22,876, of which 85% was attributable to the valve price, 7% to other material, 7% to staffing and 1% to logistics (Table 2).
Somewhat similar to a stent placed in an artery, the TAVI approach delivers a fully collapsible replacement valve to the valve site through a catheter. Once the new valve is expanded, it pushes the old valve leaflets out of the way and the tissue in the replacement valve takes over the job of regulating blood flow.
