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.
