Fatal acute bacterial myocarditis after dentoalveolar abscess

Area of Science:

• Cardiology
• Infectious Diseases
• Oral Surgery

Background:

• Dental extractions, particularly for dentoalveolar abscesses, carry a risk of systemic complications.
• Myocardial infarction (MI) is a serious cardiovascular event, typically associated with atherosclerosis.
• Bacterial infections can affect the heart, leading to conditions like endocarditis or myocardial abscesses.

Observation:

• A 19-year-old woman experienced chest pain post-dental extraction for a dentoalveolar abscess.
• Clinical and laboratory findings indicated an acute anterior myocardial infarction.
• Autopsy revealed bacteria within the myocardium.

Findings:

• The autopsy confirmed the presence of bacteria in the heart muscle.
• Crucially, there was no evidence of a myocardial abscess or infective endocarditis.
• This points to an isolated acute bacterial myocarditis.

Implications:

• This case highlights a rare but serious complication of dental procedures.
• It suggests that bacterial myocarditis can occur in the absence of typical cardiac infection markers.
• Awareness among clinicians is crucial for prompt diagnosis and management of similar presentations.
