Insights
Cor triatriatum diagnosis is enhanced by magnetic resonance imaging (MRI). MRI provides clearer anatomical detail and depicts abnormal blood flow compared to echocardiography in complex cardiac cases.
Area of Science:
- Cardiology
- Medical Imaging
Background:
- Cor triatriatum is a rare congenital heart defect characterized by a membrane dividing the left atrium.
- Accurate diagnosis is crucial for appropriate management and surgical intervention.
Abstract:
Two adult patients with cor triatriatum, which was shown by echocardiography and magnetic resonance imaging (MRI) using both spin-echo and cine-MR techniques, are presented. Spin-echo MRI clearly demonstrated an anatomical relationship between the membrane and pulmonary veins or left atrial appendage, which was not clear on transthoracic echocardiography. In addition, cine-MRI depicted abnormal flow through the fenestration of the anomalous membrane (case 1 and 2) and shunted flow through the associated atrial septal defect (case 2).
