Background:
Cor triatriatum is a rare congenital malformation in the heart. A recently published report has indicated that real time transthoracic 3-dimensional echocardiography (3DE) may replace transoesophageal echocardiography (TEE) in the diagnosis of this entity.
Material And Methods:
A patient with cor triatriatum was examined with 3DE. The results were compared to established echocardiographic methods, inclusive TEE, and to magnetic resonance imaging (MR).
Results And Interpretation:
Due to excellent resolution, TEE is still unrivalled in the assessment of some congenital heart diseases such as cor triatriatum. Real time 3DE may have the potential to replace TEE in the future, but refinement of the method is necessary.

Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
