Introduction: Left atrial appendage aneurysm is an infrequent abnormality presenting
as atrial tachyarrhythmia, progressive dyspnea, atypical chest pain, and systemic
thromboembolism. Surgical excision is considered to prevent fatal complications, even
in asymptomatic cases. The present study aimed to report a 20-year-old male who
presented with sudden onset palpitation and dyspnea.
Case Presentation: The case was really novel, because congenital left atrial appendage
aneurysm was accompanied by dilated cardiomyopathy and Left Ventricular (LV) noncompaction.
Electrocardiography (ECG) showed atrial fibrillation with Rapid Ventricular
Response (RVR) secondary to a massive congenital left atrial appendage aneurysm. At
first, left-sided weakness was diagnosed. In the next Computed Tomography (CT) scan
performed in the hospital, right temporoparietal hypodensity was detected, which was
in favor of right Middle Cerebral Artery (MCA) territory infarction that progressed with
hemorrhagic transformation.
Conclusion: The patient did not accept surgical treatment and was discharged with
medical therapy (oral anticoagulants and antiarrhythmic medications). He was expired
as a result of multiple strokes.
