Left atrial appendage function in mitral stenosis: is a group in sinus rhythm at risk of thromboembolism?

Objective: To study the left atrial appendage (LAA) function and potential for embolization in severe mitral stenosis (MS). Background: Patients with MS and atrial fibrillation or in sinus rhythm develop systemic emboli. LAA function has not been well studied in sinus rhythm. Methods: Forty consecut...

Description
Summary:Objective: To study the left atrial appendage (LAA) function and potential for embolization in severe mitral stenosis (MS). Background: Patients with MS and atrial fibrillation or in sinus rhythm develop systemic emboli. LAA function has not been well studied in sinus rhythm. Methods: Forty consecutive patients with MS (valve area ≤0.7 cm 2/m 2) were studied. LAA ejection fraction and peak emptying velocity were measured along with other data. Results: Patients were subgrouped according to LAA Doppler flow pattern. Group I ( n=13) in sinus rhythm had biphasic high velocity ≥25 cm/s. Group II ( n=13) in sinus rhythm had biphasic low velocity
