[Isolated atrial septal aneurysm: Exceptional cause of digital ischemia - a case report]. / Anévrysme isolé du septum interauriculaire : cause exceptionnelle d'ischémie digitale.

An atrial septal aneurysm (ASA) is a rare but well recognized entity characterized by saccular deformity of the atrial septum that bulges into the right or left atrium. Diagnosis can be established using transthoracic and transesophageal echocardiography. Although this abnormality is considered clinically benign, it has been independently associated with systemic or cerebral embolism. We present a unique case of isolated atrial septal aneurysm complicated by digital ischemia in a 51 years old woman.
