Cor triatriatum sinister is an uncommon cardiac abnormality characterized by a membrane that divides the left atrium into two chambers. Definitive management requires surgical resection, traditionally through sternotomy. Minimally invasive reparative techniques are associated with reduced blood loss, shorter hospitalization, faster recovery time, and improved cosmesis with excellent patient satisfaction. We present a 29-year-old woman with cor triatriatum sinister and associated atrial septal defect who underwent successful minimally invasive repair through a right periareolar approach.
