Three-dimensional transesophageal echocardiography in Ebstein's anomaly

Area of Science:

• Cardiology
• Medical Imaging

Background:

• Ebstein's anomaly is a congenital heart defect affecting the tricuspid valve.
• Traditional 2D echocardiography has limitations in fully assessing complex tricuspid valve morphology.

Observation:

• This study details the intra-operative use of 3D transesophageal echocardiography (3D TEE) during tricuspid valve repair for Ebstein's anomaly.
• 3D TEE provided detailed visualization of the tricuspid valve, right ventricle outflow tract (RVOT), and pulmonary valve before and after repair.

Findings:

• 3D TEE accurately depicted tricuspid valve leaflet morphology and coaptation, correlating with surgical findings.
• A previously undetected bicuspid pulmonary valve was identified using 3D TEE in multi-planar review mode.

Implications:

• 3D TEE enhances intra-operative assessment of complex cardiac structures in Ebstein's anomaly.
• This advanced imaging modality can reveal incidental findings, improving surgical planning and patient outcomes.
