[Intraoperative transesophageal echocardiography in diagnosing left atrial thrombosis in patients with mitral valve disease].
Intraoperative transesophageal echocardiography was conducted in 63 patients with various cardiosurgical pathology (mitral stenosis--43, combined mitral valvular disease--3, mitral incompetence--10, combined mitral-aortal valvular disease--8). Thrombosis of the left atrium was diagnosed in 13 patients. Transesophageal echocardiography in 38 patients revealed spontaneous echo-contrasting of blood currents in the cavity of the left atrium. Statistical analysis showed this sign to be characteristic of mitral stenosis complicated by thrombosis of the left atrium (p < 0.001). Transesophageal echocardiography allows visualization of thrombi of small diameter (1.0-1.5 cm). Specificity of the method is 100%, sensitivity 87%.
