Echocardiographic features of flail aortic valve

Area of Science:

• Cardiology
• Infectious Diseases
• Valvular Heart Disease

Background:

• Subacute bacterial endocarditis can lead to severe valvular dysfunction.
• Acute aortic regurgitation can precipitate fulminating congestive heart failure.
• Prosthetic aortic valve replacement is a potential treatment for end-stage valvular disease.

Observation:

• Echocardiography demonstrated marked fluttering of aortic valve cusps during systole and diastole.
• Aortic valve cusps failed to coapt in diastole, indicating severe regurgitation.
• Mitral valve showed features of acute regurgitation, and carotid pulse tracing exhibited slurring.

Findings:

• The patient underwent successful prosthetic replacement of the aortic valve.
• Postoperative echocardiography confirmed the absence of preoperative findings.
• The case highlights echocardiographic and clinical signs associated with a flail aortic valve.

Implications:

• Consider 'flail aortic valve' diagnosis in isolated aortic regurgitation without calcification and negative syphilis tests.
• Early diagnosis and intervention are crucial for managing severe aortic regurgitation.
• Echocardiography plays a vital role in diagnosing and monitoring valvular heart disease.
