title: Cryptogenic stroke in two cases with left atrial band: coincidence or cause?
abstract: Congenital left atrial band (LAB) has been reported previously. However, clinical significance of the LAB has not been clearly defined. Although LAB is generally known as a benign entity, it has been reported to be associated with Chiari's network, patent foramen ovale, mitral valve prolapse, mitral regurgitation, and supraventricular arrhythmias. In this case report we report LAB in a 34-year-old male and 56-year-old female with cryptogenic stroke. To our knowledge, the association of LAB with cardioembolic events has not been reported previously. Lack of other potential risk factors of cardioembolic stroke and normal laboratory examinations lead us to suggest that LAB might be the cause of cardioembolism in the present two cases. In conclusion, in cases with ischaemic stroke, especially the ones with undetermined aetiology, LAB should be kept in mind as a potential cause of cardioembolism.
