Cor triatriatum is a rare structural congenital cardiac anomaly in which one of the atria chambers is anatomically divided. If left untreated, cor triatriatum can eventually lead to heart failure. This case report describes our experience with two pediatric patients (a three-year-old girl and an 11-month-old male infant) who underwent surgical correction of cor triatriatum. Both patients underwent excision of the cor triatriatum membrane via cardiopulmonary bypass and had an uneventful postoperative recovery with good outcomes. Surgical repair of cor triatriatum sinister provides satisfactory short-term and long-term outcomes with a low risk of requiring additional intervention.

Article Synopsis
  • Cor Triatriatum Dexter (CTD) is a rare heart defect that splits the right atrium into two chambers, with a milder version called incomplete CTD (CTDi) that only partially divides it.
  • CTDi can be linked to interatrial septal defects and often presents in adults who experience cryptogenic strokes, usually leading to referrals for closure of a patent foramen ovale (PFO).
  • Successful PFO closure in patients with CTDi can be challenging due to complications in visualization and device deployment, making advanced imaging techniques and careful planning essential for positive outcomes.

Two patients with hypoplastic left heart syndrome (HLHS) concomitant with cor triatriatum underwent the staged Norwood procedure following hybrid palliation. Cor triatriatum was diagnosed after birth in both cases. Case 1 with aortic stenosis and mitral atresia underwent bilateral pulmonary artery banding at 2 days of age.
