Medicine · Valvular Heart Disease and Infective Endocarditis

According to the 2023 ESC Endocarditis Guidelines, which of the following is an absolute indication for urgent surgical intervention in infective endocarditis?

  • A Vegetation >10 mm on echocardiography in the absence of embolic events
  • B Heart failure due to severe aortic regurgitation from leaflet perforation
  • C Persistent bacteraemia after 5 days of appropriate antibiotics
  • D Positive blood cultures without echocardiographic vegetation
Correct answer: B. Heart failure due to severe aortic regurgitation from leaflet perforation

Explanation

Acute heart failure due to valve destruction (leaflet perforation, rupture of chordae) causing severe haemodynamic compromise is a Class I indication for emergency surgical intervention in IE, as mortality without surgery approaches 80% in this setting. The 2023 ESC guidelines emphasise urgent surgery (within 24 hours) for refractory heart failure from valvular incompetence. Vegetation > 10 mm without embolism is a relative indication for surgery to prevent embolic events. Persistent bacteraemia after 5–7 days warrants investigation for abscess or metastatic infection, and may lead to surgical decision.
