[Ventricular aneurysm as a complication of giant cell myocarditis]

Area of Science:

• Cardiology
• Pathology

Background:

• Giant cell myocarditis is a rare, aggressive inflammatory heart condition.
• Ventricular aneurysms are a known, albeit infrequent, late complication.

Observation:

• This case highlights ventricular aneurysm formation as a late sequela of giant cell myocarditis.
• The aneurysm occurred in a patient who survived the initial life-threatening phase.

Findings:

• Ventricular aneurysm formation presents a risk for sudden arrhythmic death.
• This risk persists even with preserved left ventricular ejection fraction and no recurrent inflammation.

Implications:

• Cardiac magnetic resonance imaging is crucial for detecting small, potentially asymptomatic aneurysms.
• Implantable cardioverter-defibrillators should be considered for patients with this complication to prevent sudden death.
