Aortic valve endocarditis: is there an optimal surgical timing?

Area of Science:

• Cardiology
• Cardiac Surgery
• Infectious Diseases

Background:

• Aortic valve infective endocarditis often necessitates surgery during active infection.
• Optimal timing and indications for surgical intervention remain subjects of ongoing debate.

Purpose of the Study:

• To review the benefits and risks associated with early surgical intervention in cases of aortic valve infective endocarditis.
• To identify patient subgroups that may benefit most from timely surgical management.

Main Methods:

• Review of current literature on aortic valve endocarditis and surgical outcomes.
• Analysis of echocardiographic findings and clinical indicators for surgical decision-making.
• Identification of high-risk patient profiles and prognostic factors.

Main Results:

• Urgent surgery is indicated for patients with acute aortic regurgitation and signs of poor tolerance.
• Severe perivalvular involvement and high embolic risk are key indications for early surgery.
• Echocardiography is vital for assessing embolic risk and guiding therapeutic strategies.

Conclusions:

• Patients with severe aortic leaflet destruction, congestive heart failure, perivalvular extension, uncontrolled infection, or high embolic risk have poor prognoses with medical therapy alone.
• Early surgical intervention is essential for 'complicated' aortic endocarditis unless significant comorbidities preclude it.
• Prosthetic valve endocarditis and cerebral complications present complex challenges for surgical decision-making.
