Aneurysm of left ventricle secondary to bacterial endocarditis
Abstract:
Three cases are described of aneurysms of the area of fibrous continuity between the aortic and mitral valves, each associated with infective endocarditis of the aortic valve. In two cases surgical treatment was successful, one of these having been diagnosed by angiography prior to operation. The other case was discovered only at autopsy, but the histologic findings showed the lesion to be a true aneurysm. Although some cases have been successfully managed by operation, most have proved fata. These cases and the previous successes illustrate the potential value of urgent operation.
Insights
Aortic valve aneurysms associated with infective endocarditis can be successfully treated with urgent surgery. Early diagnosis via angiography improves surgical outcomes for these rare, potentially fatal cardiac lesions.
Area of Science:
- Cardiology
- Cardiac Surgery
- Infective Endocarditis
Background:
- Aneurysms in the fibrous continuity between aortic and mitral valves are rare cardiac pathologies.
- These lesions are often associated with infective endocarditis, particularly of the aortic valve.
Observation:
- The study presents three cases of aortic-mitral valve fibrous continuity aneurysms.
- Each case involved concurrent infective endocarditis of the aortic valve.
- Diagnosis was achieved via angiography in one case, while another was identified post-mortem.
Findings:
- Histologic examination confirmed a true aneurysm in the autopsy case.
- Surgical intervention was successful in two of the three presented cases.
- Despite successful surgical management in some instances, the overall mortality for these aneurysms remains high.
Implications:
- Urgent surgical intervention should be considered for patients with aortic valve aneurysms and infective endocarditis.
- Early diagnosis, potentially aided by angiography, can significantly improve treatment outcomes.
- These findings highlight the critical role of prompt surgical management in improving survival rates for this severe cardiac condition.
