Abstract
Left atrial aneurysm is a rare condition. Only 29 cases have been reported, to our knowledge. We report 1 such case in a 24-year-old man who complained of dyspnea and arrhythmias. Diagnosis was suspected on review of chest roentgenogram and confirmed by echocardiography and cardiac catheterization. Surgical repair was achieved without complications, and preoperative symptoms disappeared completely. According to the literature, these patients are almost always asymptomatic. When present, the most common symptoms are arrhythmias, heart failure, emboli, and chest pain. This lesion is seen mainly in young adults (mean age, 23.5 years). The diagnosis should be confirmed by echocardiography, nuclear imaging, and cardiac catheterization. A review of the literature indicates that surgical repair can be accomplished with low mortality and that arrhythmias usually disappear postoperatively.
