Minimally invasive repair of fenestrated atrial septal aneurysm.

Background: Atrial septal aneurysms (ASAs) are uncommon but are associated with significant embolic morbidity when an interatrial communication is present. Although surgical reconstruction has traditionally been approached through a median sternotomy, minimally invasive techniques may be employed to reduce pain and recovery time.

Methods: We present a video-assisted technique via right inframammary minithoracotomy utilizing peripheral cannulation for cardiopulmonary bypass.
