In patients with rheumatic mitral valve disease presence of thrombus (THR) and spontaneous echo centrast (SEC) in left atrium (LA) and LA appendage (LAA) have been considered to be predictors for embolic events. However impact of morphologic characteristics of LA THR in relation to embolic events has not been investigated. This study aims to evaluate whether morphologic characteristics of LATHR is associated with embolic events, and to assess the grade of LASEC in relation to morphologic characteristics of LA THR in patients with rheumatic mitral valve disease. Study population comprised 474 patients of rheumatic mitral valve disease (F 320, M 154, mean age 40±16) in whom transesophageal echocardiography was performed prior to mitral valve surgery. Pure or predominant mitral stenosis and mitral regurgitation were detected in 333 and 141 of patients, respectively. Rhythm was atrial fibrillation in 267 patients. Embolic event (n=26) was defined as presence of documented sytemic arterial embolism recently, 30 day s prior to transesophageal echocardiography. Thrombus w as detected in lül(LA 13, LAA 62 and LA+LAA 26) and SEC in 212 of patients. Morphology of THR was defined as the ir age (organ i sed vs non organised;54 vs 47), surface characteristics (smooth vs irregular; 69 vs 32), diameter (cm) and thickness of THR measured by transesophageal echocardiography and intraatrial extension score of THR (from 1 to 5). Overall, mean age (pKeywords: transesophageal echocardiography, thrombus, surface irregularity
