  2. EPIDEMIOLOGY • AS is the most common form of the adult valvular heart disease • Population Incidence in USA of moderate-severe AS is 0,4% and in aged > 75 y is 2,8% (4% > 85 y) • 33% of patients with severe AS and NYHA fc III-IV did not undergo intervention (high risk).

Stenosi aortica calcifica Valvuloplastica percutanea • * ”PONTE ALLA CHIRURGIA: • -AREA VALVOLARE <0,4 CMQ, • -FE < 0,35 • -IV classe NYHA • Pazienti in scompenso cardiaco refrattario e disfunzione multiorgano • Pazienti in shock • Pazienti in cui non è possibile la sostituzione • valvolare(?) • Paziente sintomatici che devono essere sottoposti ad interventi chirurgici urgenti per altra patologia
