Echocardiography in aortic dissection

#Echocardiography_in_aortic_dissection:
1-#Transthoracic
*75% diagnostic Type A (ascending),
*40% descending (Type B)
*can identify complications (e.g. aortic regurgitation, regional wall abnormalities in cardiac ischaemia, cardiac tamponade)
2-#Transoesophageal (TOE)
*Much higher sensitivity/specificity, though operator-dependent, need sedation, and is less available
*Useful in ICU / perioperative
*Upper ascending aorta and arch not well visualised.
