To compare transesophageal echocardiography, real time three-dimensional transesophageal echocardiography and 64-slice computed tomography methods to measure atrial septal defect size before transcatheter closure.
Patients who were subjected to percutaneous closure were selected. Two-dimensional echocardiography, real time 3D-transesophageal echocardiography and computed tomography were performed. Maximum and minimum diameters were measured.
Twenty one patients were included (female 66%, mean age: 40.8 卤 21.4). All patients successfully underwent percutaneous closure. The correlations between the measurements obtained by the three techniques were analysed (maximum diameter, two-dimensional vs 3D-echocardiography: 14.7 卤 9.2 vs 15.3 卤 9.3, ICC = 0.99, P < .001; two-dimensional echocardiography vs tomography: 15.3 卤 9.5 vs 17.1 卤 10.6, ICC = 0.88, P < .001; tomography vs 3D-echocardiography: 17.1 卤 10.6 vs 15.8 卤 9.6, ICC = 0.91, P < .001. Minimum diameter: two-dimensional vs 3D-echocardiography: 8.3 卤 4.6 vs 8.7 卤 4.7, ICC = 0.99, P < .001; two-dimensional echocardiography vs tomography: 8.8 卤 4.6 vs 12.3 卤 6.2, ICC = 0.67, P = .001; tomography vs 3D-echocardiography: 12.3 卤 6.4 vs 9.1 卤 5.0, ICC = 0.74, P < .001).
Two-dimensional echocardiography, 3D-echocardiography and tomography are complementary techniques with a good correlation. These findings could be relevant for the selection of the size of the device.
