Incidence of Spontaneous Echocontrast in Left Atrium in Mitral Stenosis Detected by Transoesophageal Echo Cardiography and Related Factors

The incidence of left atrial (LA) spontaneous echo contrast (SEC) and the clinical and echocardiographic variables related to it were prospectively evaluated in a series of 60 patients with mitral stenosis (MS) undergoing transoesophageal echocardiography (TEE) with a 5 MHz multiplane transducer. LA-SEC was found in 39 patients (65 %) employing TEE. Statistical analysis showed a significant relationship between the presence of SEC and MS without mitral regurgitation (MR) (P«)’o5), MS with ~MR grade II
