Anatomic narrowing at the left atrial appendage opening was identified using advanced echocardiography techniques. This unusual finding was visualized with two-dimensional color Doppler and continuous-wave Doppler transesophageal echocardiography.

Area of Science:

Cardiology
Medical Imaging

Background:

The left atrial appendage (LAA) is a common source of thrombi in patients with atrial fibrillation.
Anatomic variations of the LAA can influence thrombus formation and stroke risk.

Observation:

This case report details an unusual anatomic narrowing at the orifice of the left atrial appendage.
The narrowing was clearly visualized using transesophageal echocardiography.

Findings:

Two-dimensional color Doppler and continuous-wave Doppler transesophageal echocardiography were utilized to demonstrate the LAA narrowing.
The specific nature and degree of the narrowing were characterized by these advanced echocardiographic modalities.

Implications:

Understanding such rare anatomic variations is crucial for accurate risk stratification and treatment planning.
