Echocardiographic diagnosis of left atrial thrombus - a case report

We report a case of mitral stenosis with echocardiographic findings we consider diagnostic of left atrial thrombus. Scanning of the ultrasound beam from the left ventricular basalward to the left atrium (LA) demonstrates a consistent group of strong echoes within the LA and extending into the mitral orifice. Massive left atrial thrombosis was confirmed at operation.
