Your doctor can usually request a trans-oesophageal echocardiogram to evaluate a stroke or transient ischemic attacks (mini strokes) as a result of blood clots. It is also useful to assess the success of previous heart procedures including valve replacements and bypass surgeries, as well as other heart conditions including congenital heart diseases.
Trans-oesophageal echocardiogram detects blood clots, tumours and abnormal masses within the heart, which may not be seen properly using standard echocardiographic images. It can also detect particular valve problems including infected heart valves.
