Abstract
Cor triatriatum sinister is a congenital cardiac anomaly involving a fibromuscular membrane that divides even the left atrium or the right into two chambers. This abnormality has been reported in only 0.1% to 0.4% of patients with congenital heart disease. Most patients are diagnosed with the condition in infancy or childhood; adult cases are rare. We describe three rare complications of cor triatriatum. The first case is about pulmonary embolism complicating a cor triatrium dextran in a 44-year-old man, which has never been reported, at least to the best of our knowledge. He underwent curative resection of the membrane and was asymptomatic after that. The second case is about sudden death on a cor triatrium sinistrum 9-month-old infant. The last one is an about 45-year-old male patient admitted with atrial fibrillation revealing cor triatrium.
