La “trasferibilita’” dei risultati clinici tra device. Il caso dello stent medicato Roberto Violini Cardiologia Interventistica AO S. Camillo Forlanini - Roma
L’angioplastica coronarica RESTENOSI 30 -40% solo pallone 15 -20% stent < 6 % stent medicato
Lo stent
DES – Drug eluting stent
Lots of DES ever received CE-Certificate !
Transferability of data between different DES: 1. Does a CE mark mean, a stent is safe and effective ? 2. Are all DES the same ? (DES-1 vs. DES-2) 3. Can data be transferred for modifications of a specific stent ? (DES-1 a vs. DES-1 b)

Does a CE mark mean, a stent is safe and effective ? Restenosis after 6 Months

DES – Una storia vera • La multinazionale A compra la multinazionale B • Per motivi di antitrust, A rivende alcuni brevetti alla multinazionale C • A e C concordano il comarketing per il DES X • Successivamente A realizza lo stent X 1 C realizza lo stent X 2
DES X: First in man CE mark
Stent X prodotto da A e C Stent X 1 prodotto da A Stent X 2 prodotto da C Changes in Stent Material Randomized Trial are required Changes in Stent Design Registry are enough

Conclusione Al di la’ della problematica regolatoria e, per le strutture pubbliche, della normativa per gli acquisti esiste la responsabilita’ della scelta che grava sull’utilizzatore finale. Attenta valutazione dei risultati clinici e spirito critico sono gli strumenti per arrivare ad una scelta responsabile dei device.
