Algorithme
Evaluation du risque
SPEED protocol
Utilisation de l'ECMU : Le protocole SPEED combine l'échocardiographie transthoracique et l'échographie de l'aorte abdominale.
Cible :
- dissection aortique de type A de Standford
- épanchement péricardique,
- un flap intimal
- un diamètre de l'aorte initial (AOFT) > 35 mm mesuré d'une paroi interne à l'autre à 20 mm de l'anneau aortique en fin de diastole
- dissection aortique de type B de Standford
- un flap intimal dans l'aorte abdominale
