経食道心エコー図法による左心房内モヤモヤエコーの評価

抄録

The inside of the left atrium can be precisely observed by transesophageal echocardiography-inserting an ultrasonic probe into the esophagus. If it is used on a patient with atrial fibrillation, mitral stenosis, etc., a smoke-like echo called the spontaneous echo contrast will be observed. Since it is said that the spontaneous echo contrast is related to thrombosis, an early diagnosis is needed. However, validation procedure is a precedence scale and is not established. We compared a doctor's diagnostic validation with a time shift of picture image power (the near mitral value of a left-atrium picture image), in order to establish the evaluation of the spontaneous echo contrast. Consequently, we have evaluated the spontaneous echo contrast in detail, attained a result which can support a doctor's diagnosis.
