Pak Heart J Jan ;51(1):71-6.

Objective: To determine the frequency of left atrial thrombus in patients with mitral stenosis having atrial fibrillation. Methodology: This cross sectional study was conducted at Bolan Medical College and Sandeman Teaching Hospital, Quetta. from 17 February 2015 to 2016. Both male and female patients between 25 to 70 years with moderate to severe mitral stenosis and atrial fibrillation were included while patients with mitral stenosis and normal sinus rhythm, mitral regurgitation, congestive heart failure, significant aortic value or coronary artery disease were excluded. Results: In this study a total of 110 patients with mean age of 45+-2.16 years were included with 35% patients were males. About 22% patients were hypertensive and 80% patients were non hypertensive, 27% were diabetics.About 70% patients had BMI <30 while 30% patients had BMI > 30, 28%patients had moderate mitral stenosis and 72% patients had severe mitral stenosis with left atrial thrombus in 27% patients. Conclusion: Our study shows that patients with AF have raised risk of atrial thrombus. Therefore proper screening for thrombus is needed in patients with AF so that in time anti coagualtion can be done.
