Three-dimensional echocardiographic image of atrial septal aneurysm: report of two cases.
Atrial septal aneurysm (ASA) is a rare congenital anomaly. It may occur as an isolated pathology or in association with other cardiovascular lesions such as mitral valve disease, atrial septal defect, and others. The diagnosis of ASA became more widely recognized with the use of 2-dimensional echocardiography. Three-dimensional echocardiography is a recently developed imaging technique. It can be used as an adjunct to conventional transesophageal echocardiography. Images of different aspects of cardiac chambers and valves can be obtained with 3-dimensional echocardiography. This paper reports on 2 cases of different types of ASA imaged by 3-dimensional echocardiography. The images were obtained from the left and right atriums, respectively. The 3-dimensional image taken from the left atrium showed the ASA to be a localized concave structure, and the 3-dimensional image taken from the right atrium showed the ASA to be a localized bulging structure. Our pictures are the first reported 3-dimensional echocardiographic images of ASA. We hope this report will allow for a more comprehensive understanding of its pathology.
