Blind spot of TEE for aortic imaging – Cardiology MCQ – Answer

Correct answer: b) Distal ascending aorta

Distal ascending aorta just before the innominate artery is difficult to image with trans esophageal echocardiography because of the intervening right bronchus and trachea. Rest of the thoracic aorta including descending thoracic aorta from left subclavian artery to celiac trunk can be imaged well by trans esophageal echocardiography. Both short axis and long axis images are possible by multi plane TEE.
