Annals of Cardiac Anaesthesia. 2015 Jan-Mar ; 18(1): 69-73.http://imsear.searo.who.int/handle/123456789/156504Echocardiography provides a useful tool in the diagnosis of many congenital heart diseases, including atrial septal defects, and aids in further delineating treatment options. Although two-dimensional echocardiography has been the standard of care in this regard, technological advancements have made three-dimensional echocardiography possible, and the images obtained in this new imaging modality are able to accurately portray the morphology, location, dimensions, and dynamic changes of defects and many other heart structures during the cardiac cycle.enAtrial septal defectsCongenital heart diseaseEchocardiographyTransthoracic echocardiographyTransesophageal echocardiographyThree- dimensional echocardiographyTwo dimensional echocardiographyEchocardiography --methodsEchocardiography, Three-Dimensional --methodsEchocardiography, Transesophageal --methodsHeart Defects, Congenital --diagnosisHeart Diseases --congenitalHeart Diseases --diagnosisHeart Septal Defects, Atrial --diagnosisHumansArticle
