What is Cor Triatriatum

Cor Triatriatum is a rare congenital heart defect characterized by the presence of a membrane or fibrous band that divides the atrium into two chambers. This condition occurs during fetal development when the partition that normally forms between the left and right atrium fails to fully develop, resulting in an abnormal division. The membrane or band can partially or completely separate the atrium, leading to impaired blood flow and potential complications.

Symptoms: The severity of symptoms varies depending on the degree of division. Mild cases may remain asymptomatic, while more severe cases can present with symptoms such as shortness of breath, fatigue, palpitations, and poor growth in infants.

Diagnosis: Cor Triatriatum is typically diagnosed through various imaging techniques, including echocardiography, cardiac MRI, or CT scan. These tests help visualize the abnormal partition and assess its impact on blood flow.

Treatment: The management of Cor Triatriatum depends on the severity of the condition and associated symptoms. Mild cases may not require intervention, while more severe cases often necessitate surgical intervention to remove or repair the membrane/band and restore normal blood flow.

It is important for individuals with Cor Triatriatum to receive regular follow-up care to monitor their heart function and address any potential complications.
