Major echocardiographic criteria include the following:

  • Echocardiogram positive for IE, documented by an oscillating intracardiac mass on a valve or on supporting structures, in the path of regurgitant jets, or on implanted material in the absence of an alternative anatomical explanation

  • Myocardial abscess

  • Development of partial dehiscence of a prosthetic valve

  • New-onset valvular regurgitation
