Acute coronary embolism complicating bacterial endocarditis: operative treatment
Insights
Bacterial endocarditis can cause heart attacks due to valve calcification and emboli. Prompt valve replacement successfully removed the embolus, preventing further cardiac events.
Area of Science:
- Cardiology
- Infectious Diseases
- Cardiac Surgery
Background:
- Bacterial endocarditis is a serious infection affecting heart valves.
- Myocardial infarction (heart attack) can be a complication of endocarditis.
- Aortic valve disease requires timely surgical intervention.
Observation:
- A patient with bacterial endocarditis experienced an acute myocardial infarction.
- Coronary arteriography showed an occlusion in the left anterior descending artery.
- A calcific embolus originating from the infected aortic valve was identified.
Findings:
- Surgical removal of the calcific embolus during aortic valve replacement was successful.
- The patient had an uncomplicated immediate postoperative recovery.
- Recurrent paravalvular aortic regurgitation occurred late postoperatively, requiring further intervention.
Implications:
- This case highlights the embolic potential of bacterial endocarditis affecting the aortic valve.
- Early diagnosis and intervention are crucial for managing infective endocarditis and its complications.
- Management of aortic valve disease, especially post-endocarditis, can be complex and may require multiple procedures.
Abstract:
A patient with bacterial endocarditis and no previous history of angina substained an acute anterolateral myocardial infarction while awaiting surgery. Selective coronary arteriography revealed a filling defect in the left anterior descending coronary artery with limited flow beyond the area of occlusion. A calcific embolus from the infected aortic valve was removed at the time of valve replacement, and the patient had an uneventful immediate postoperative course. Late postoperatively paravalvular aortic regurgitation recurred before and after a second repair.
