Why the study?
Does color Doppler tissue imaging detect left atrial appendage dysfunction in patients with mitral stenosis in sinus rhythm compared to healthy subjects?
Does color Doppler tissue imaging detect left atrial appendage dysfunction in patients with mitral stenosis in sinus rhythm compared to healthy subjects?
Color Doppler tissue imaging can successfully quantify LAA contraction and demonstrates significant LAA dysfunction in patients with mitral stenosis in sinus rhythm, particularly those with spontaneous echo contrast.

LAA dysfunction may occur in mitral stenosis despite sinus rhythm; leaves open whether imaging findings should guide anticoagulation.
Topsakal et al. (2004) studied this question.
