Diverticulum of the posterior left atrial wall.
Diverticula of the left atrium are very rare malformations of unknown etiology and may be associated with arrhythmias, thromboembolism, or mitral valve regurgitation. We report a patient with suspected coronary artery disease (CAD) in whom we performed a low-dose computed tomography coronary angiography using prospective electrocardiogram triggering. CAD could be ruled out. Incidentally, we found a diverticulum on the posterior wall of the left atrium combined with an interatrial septal aneurysm. The diagnosis was confirmed by transthoracic echocardiography.
