Assessment of left atrial appendage wall dynamics in patients with pure rheumatic mitral stenosis in sinus rhythm and atrial fibrillation; a transesophageal Doppler tissue echocardiographic study.

ABSTRACT

Background: thrombus formation has predilection to form within the left atrial appendage [LAA] in patients with rheumatic mitral stenosis both in atrial fibrillation and in sinus rhythm. Transesophageal echocardiographay [TEE] was used for LAA evaluation however it has its own limitations:
