FREQUENCY OF LEFT ATRIAL AND APPENDAGE THROMBUS IN PATIENTS PRESENTING WITH SEVERE MITRAL STENOSIS

Objective: To determine the frequency of left atrial and appendage thrombus in patients with severe mitral stenosis.

Methodology: The study design was descriptive cross sectional. A total of 142 patients meeting our inclusion criteria were enrolled through nonprobability sampling technique in this research study. A well-designed questionnaire was used for data collection of admitted patients. 

Results: Out of 142 patients, 111 (78.16%) male patients were recorded, and 31 (21.83%) female patients were recorded. Mean and SDs for age was 54+5.68. Mean and SDs for height was 5.8+0.08. Mean and SDs for weight was 90+5.03. Mean and SDs for BMI was 31.12+1.74. Mean and SDs for LA&LAA Size was 42+0.56. 122 (85.91%) patients were recorded with LA & LAA Thrombus.

Conclusion: The frequency of left atrial and appendage clots on trans-esophageal echocardiography in patients with severe mitral stenosis is common and more frequent in patients with AF and LA size > or = 45 mm.
