Three-dimensional transthoracic echocardiography to evaluate cor triatriatum in the adult

Area of Science:

• Cardiology
• Medical Imaging
• Congenital Heart Disease

Background:

• Cor triatriatum is a rare congenital anomaly characterized by a septum dividing the left atrium.
• Diagnosis is often delayed due to variable fenestration size and number.
• Echocardiography is the primary diagnostic modality, with transesophageal echocardiography (TEE) generally preferred over transthoracic echocardiography (TTE).

Observation:

• This report details the first known use of three-dimensional transthoracic echocardiography (3D-TTE) for diagnosing cor triatriatum.
• 3D-TTE provides enhanced visualization of the intra-atrial septum compared to traditional 2D echocardiography.
• The study highlights the potential of 3D-TTE in overcoming limitations of conventional imaging methods.

Findings:

• Three-dimensional transthoracic echocardiography successfully visualized the partitioning septum in a case of cor triatriatum.
• This technique offers detailed anatomical information, aiding in accurate diagnosis.
• The findings suggest 3D-TTE is a valuable non-invasive tool for evaluating complex cardiac anatomy.

Implications:

• 3D-TTE may offer a safer and more convenient alternative to TEE for diagnosing cor triatriatum.
• This advanced imaging modality can improve diagnostic accuracy and patient management for this rare condition.
• Further research into 3D-TTE applications in congenital heart disease is warranted.
