Objective
Accurate assessment of atrial septal defect (ASD) size, length and relationship of the ASD to surrounding cardiac structures is essential for successful closure of ASD. Appropriate device selection is also dependent to the exact measure of the ASD. Guidance for device closure of ASD with three-dimensional transesophageal echocardiography (3DTEE) is the method of choice in experienced centers which provides size, shape, orientation, numbers of orifices and rim status in one single en face view. In our study, we aimed to compare the defect sizes measured with two-dimensional transesophageal echocardiography(2DTEE) and 3DTEE in patients who had secundum ASD.
Methods
Thirteen consecutive patients ( 9 females [70 %]) with ostium secundum ASD who underwent transcatheter ASD closure were enrolled to our study. The mean age was 36.0 ± 15.1 years. Real time 3DTEE and 2DTEE images were taken during the procedure.
