Cor Triatriatum Sinister Combined with Dilated Cardiomyopathy

Mei-lian Cai, Guo-qiang Zhong*

Background: Cor Triatriatum Sinister (CTS) is a relatively rare congenital heart disease, and a membrane divides the Left Atrium (LA) into two cavities that communicate through a small opening. It is often associated with other congenital cardiac anomalies; however, it associated with other cardiomyopathy has not been reported.

Patients and method: A 33-year-old female presented with fatigability, facial surface and double lower limb edema for more than 1 week. The patient underwent Electrocardiogram (ECG), Transthoracic Echocardiography (TTE) and cardiac Magnetic Resonance Imaging (MRI), which showed the presence of a membrane in LA, indicated cor triatriatum (complete type), smooth blood flow at the traffic port, and no obvious obstruction to the blood flow. She was diagnosed with Atrial Fibrillation (AF), CTS with Dilated Cardiomyopathy (DCM).

Results: The patient received medical treatments for heart failure. After that, she was treated with AF radiofrequency ablation. After discharge, the clinical manifestation of fatigability, facial surface and double lower limb edema did not recur.

Conclusion: The symptoms of patients with cor triatriatum associated with other heart disease may not be caused by cor triatriatum. We must pay attention to identification.
