Introduction: Atrial septal aneurysm diagnosed by transesophageal and transthoracic echocardiography. Atrial septal aneurysm (ASA) is a rare anomaly with unclear clinical importance. Transesophageal echocardiography (TEE) is better than transthoracic echocardiography (TTE) in assessment of the atrial septum. The aim of the study was to assess the advantage of TEE in comparision to TTE for the diagnosis of ASA and other structural abnomalities coexisting with ASA, and to define when this method is particularly useful. Methods: The study group consisted of 68 patients with ASA (age 14-78 years, mean 45.7±16.5), diagnosed by TEE and TTE. The following parameters were compared in both methods: the dimensions of ASA, its amplitude and motion direction and another abnomalities (interatrial shunts, mitral prolaps, Chiari’s network etc.). Results: Mean values of dimension, amplitude and direction of the ASA motion in TEE and TTE did not differ significantly. TEE was more sensitive for the diagnosis of ASA and small or multiple shunts. TEE enabled the diagnosis of ASA in 10 cases, which were not recognized by TTE and ruled out ASA in 1 case. We found no potential embolic material in our patients. Conclusion: ASA diagnosed by TTE is not an absolute indication for TEE, but if ASA is connected with clinical symptoms suggestive for peripheral embolism or the suspicion of abnormal structures in the atrium, TEE should be performed.
