[Right atrial aneurysm after chest trauma: late presentation].

Area of Science:

• Cardiology
• Cardiac Surgery
• Medical Imaging

Background:

• A 59-year-old male with a history of chest trauma presented with fatigue and palpitations.
• Initial imaging suggested cardiac anomalies like cor triatriatum or Ebstein's anomaly.

Observation:

• The patient experienced recurrent atrial tachycardia despite pharmacological conversion.
• Repeat echocardiography revealed a right atrial aneurysm as the underlying cause.

Findings:

• The right atrial aneurysm was successfully treated with electrical cardioversion.
• The patient remained asymptomatic for 18 months post-procedure with carvedilol and warfarin therapy.

Implications:

• This case highlights the importance of comprehensive echocardiography in diagnosing rare cardiac conditions.
• Right atrial aneurysms should be considered in the differential diagnosis of unexplained arrhythmias.
• Effective management strategies involve electrical cardioversion and appropriate anticoagulation/medication.
