Abstract

Cor Triatriatum Sinister is a rare congenital abnormality, usually diagnosed in childhood; few cases remain asymptomatic and are diagnosed in adulthood. Triatrial heart is a rare congenital abnormality, reported by Jeiger at the autopsy, in 0.4% of patients with congenital heart disease, and found in less than 0.1% of clinically diagnosed cardiopathies. Though it was first described by Church in 1868, as a left atrium divided by an abnormal septum, the name “cor triatriatum” was given by Borst in 1905. It involves usually the left atrium (cor triatriatum sinister) and rarely the right atrium (cor triatriatum dexter), in this review, we will be discussing cor triatriatum sinister (CTS).
