RESUMEN
To evaluate systolic and diastolic dysfunction of left ventricle in patients with first anterior myocardial infarction and its relation to one month mortality after myocardial infarction; in this study mitral annulus motion velocity that was recorded by Tissue Doppler Imaging [TDI]. The study included 111 consecutive individuals, 81 patients with first anterior myocardial infarction, [in wich 72 patients who survived and 9patients dead one month after admission], 30 individuals which matched with the studying group selected as a control group. Longitudinal function of left ventricle was evaluated by the use of mitral annular velocities in this study. Patients with myocardial infarction showed significant reduction in peak systolic, early diastolic and late diastolic annular mitral velocities comparing with control group in all studied segments. There was a good correlation between Left Ventricle Ejection Fraction [LVEF] and all mitral valve annular velocities. Also Myocardial Performance Index [MPJ more than 0.8 and [Regional Wall Motion Scoring Index [RKMSJ more than 1.77 had high sensitivity [0.94 and 0.96 respectively] in predicting death in follow-up period. Reduced peak systolic mitral annulus velocity is an expression of regionally reduced systolic function. Reduced peak early and late diastolic velocities reflect regional diastolic dysfunction. Also Regional wall motion score index and myocardial performance index can be useful in predicting death after myocardial infarction
RESUMEN
Mobile luminal mass of aortic arch is an unusual finding in patients with peripheral embolization. To search the source of these emboli, aortic arch mass should be considered. To our knowledge, transesophageal echocardiography [TEE] can be a useful modality to demonstrate the nature and exact location of the mass. This report is illustrative of a large mobile aortic arch mass, histologically thrombus, found by TEE in a 48- year-old woman with embolic symptoms
