A rare, giant congenital left atrial appendage aneurysm was found in a 19-year-old girl. This is the largest reported case of this condition occurring without any symptoms.
Area of Science:
- Cardiology
- Congenital Heart Disease
Background:
- Congenital left atrial appendage aneurysms are rare cardiac malformations.
- Giant aneurysms are exceptionally uncommon, particularly in asymptomatic individuals.
Observation:
- A 19-year-old female presented with an incidentally discovered giant congenital left atrial appendage aneurysm.
- The aneurysm measured significantly larger than previously reported cases.
Findings:
- The patient was asymptomatic despite the large size of the left atrial appendage aneurysm.
- This finding challenges typical clinical presentations and diagnostic expectations for such conditions.
Implications:
- Highlights the possibility of asymptomatic presentation of giant congenital left atrial appendage aneurysms.
- Suggests the need for careful evaluation and consideration of conservative management in select asymptomatic cases.
- Contributes to the understanding of the spectrum of congenital cardiac anomalies.
