title: Cor triatriatum sinister.
abstract: The cor triatriatum sinister is an uncommon congenital cardiac anomaly and reports in the literature are limited. It is often associated with other cardiac malformations, such as atrial septal defect, transposition of the great arteries, tetralogy of Fallot or atrioventricular septal defect. We present here a 6-year old boy who was diagnosed with cor triatriatum sinister, initially showing symptoms similar to mitral valve stenosis and congestive heart failure, and who underwent subsequent surgical correction using a left atrial approach. The fibromuscular membrane, separating the pulmonary veins from the mitral valve, was completely resected and postoperative echocardiography showed unobstructed pulmonary venous flow.
