Mitral valve aneurysm: clinical features, echocardiographic-pathologic correlations.

C L Reid, A N Chandraratna, E Harrison

Journal of the American College of Cardiology

|September 1, 1983

Summary

Mitral valve aneurysms, often linked to aortic valve endocarditis, can cause serious heart issues. Early diagnosis via echocardiography is crucial for timely intervention and preventing complications like mitral regurgitation.

Background:

Mitral valve aneurysms are rare but serious cardiac conditions.
They commonly arise secondary to infective endocarditis of the aortic valve.

Purpose of the Study:

To describe the clinical and echocardiographic-pathologic findings of mitral valve aneurysms.
To highlight the diagnostic utility of echocardiography and the importance of early detection.

Main Methods:

Case series review of five patients with pathologically confirmed mitral valve aneurysms.
Correlation of clinical presentation, echocardiographic findings, and pathological examination.

Main Results:

Aneurysm formation is likely due to regurgitant jets from aortic valve destruction impacting the mitral valve.

Echocardiography revealed a characteristic leaflet bulge into the left atrium.

No specific clinical features were identified for diagnosis.

Conclusions:

Mitral valve aneurysms can lead to severe complications, including mitral regurgitation and pulmonary edema.
Two-dimensional echocardiography is key for preoperative diagnosis.
Prompt diagnosis and management, including potential repair or valve replacement, are essential.
