The purpose of this study was to evaluate if two-dimensional echocardiography could identify fresh thrombi on the basis of ultrasound texture characteristics. Thirty-one intracavitary thrombi from 16 autopsy specimens were obtained. Two-dimensional echocardiographic images were obtained by a Toshiba SSL53M phased array sector scanner with a 2. 4 MHz transducer. Fifteen of 31 thrombi were classified as fresh on the basis of the echocardiographic images. The anatomo-pathological analysis confirmed this classification in 9 of the 15 cases. In clinical settings fresh thrombi can disappear. We have observed the disappearance of thrombi, without signs of embolization, in 15 cases, and the marked reduction in size in 1 case. Retrospectively all the thrombi which disappeared showed tissue characteristics by two-dimensional echocardiography similar to fresh thrombi examined in vitro. Two-dimensional echocardiography seems helpful in identifying fresh thrombi by qualitative evaluation of ultrasound texture characteristics.
