Ebstein's anomaly assessed by real-time 3-D echocardiography.

The outcome of patients with Ebstein's malformation depends mainly on the severity of the tricuspid valve malformation. Accurate description of the tricuspid anatomy by two-dimensional echocardiography remains difficult. We applied real-time three-dimensional echocardiography to 3 patients with Ebstein's anomaly.

Real-time three-dimensional fetal echocardiography using matrix probe.

Objective: To investigate the feasibility of using real-time three-dimensional echocardiography (3DE) to evaluate the fetal heart.

Methods: Sixty fetuses were studied with gestational age between 22 and 34 weeks. The fetal heart was normal in 44 fetuses.

Assessment of atrial septal defect size with 3D-transesophageal echocardiography: comparison with balloon method.

Background: Transcatheter closure of atrial septal defect (ASD) is an alternative approach to surgery in selected patients. Balloon stretched diameter (BSD) is considered as the standard way of measuring ASD size. Three-dimensional transesophageal echocardiography (3D-TEE) provides views of the ASD allowing its measurement and identifying its spatial relation with neighboring structures.
