We present a case of a rare complication of atrial septal defect (ASD) device closure causing cor triatriatum dextro iatrogenica. A 29-year-old female presented with sudden onset dysarthria and ataxia and was found to have basilar and thalamic infarcts. Further evaluation using transthoracic echocardiography revealed an ASD which was repaired using the Gore HELEX septal occluder. Transesophageal echocardiography done after 2 months of ASD closure revealed an interesting finding termed cor triatriatum dextro iatrogenica. We briefly describe the case and discuss the relevant literature.

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.
