Interference by air in the lungs, which is usual for transthoracic echocardiography (TTE) is also avoided. As the imaging is in the near field, higher frequency transducers can be used, providing better image resolution. TEE imaging frequency is of the order of 5 &#8211; 10 MHz. TEE is very useful for imaging the posterior structures of the heart like the left atrium. Clots in the left atrial appendage can be seen well on TEE. Small vegetations of infective endocarditis are also better seen on TEE than on TTE. Mitral valve morphology and regurgitant jets can be imaged well on TEE.<\/p>\n<p>Intraoperative TEE is an important application being increasingly used by cardiac surgeons to assess the results of surgical repair. Since it does not interfere with the operative field, results of procedures like mitral valve repair can be assessed soon after restarting the heart even before closure of the chest wall. TTE does not permit intra operative evaluation during open heart surgery.<\/p>\n<p>Intraoperative TEE is being increasingly used in important non cardiac surgery to supplement hemodynamic monitoring as it provides a real time visual assessment of cardiac function. This is more important in those with pre-existing cardiovascular disease. Yoo MC and colleagues have reviewed the advantages and disadvantages of perioperative use of TEE for liver transplantation surgery [1].<\/p>\n<p>TEE is also being used in the cardiac catheterisation laboratory to evaluate results of procedures like device closure of atrial and ventricular septal defects. The proper seating of the device and potential impingement on surrounding vital structures can be accurately assessed by TEE during the interventional procedure without compromising the sterile operating field.<\/p>\n<p><span style=\"color: #0000ff;\"><strong>Potential risk&nbsp;of transesophageal echocardiography<\/strong><\/span><\/p>\n<p>Presence of esophageal varices is a potential risk for TEE as there is risk of gastrointestinal bleeding. But a study evaluating 14 patients with grade 1 or 2 esophageal&nbsp;varices and no&nbsp;recent bleed, did not document&nbsp;any serious complications after TEE. <em>Transgastric TEE views were avoided in these patients <\/em>[2].<\/p>\n<p><span style=\"color: #0000ff;\"><strong>References<\/strong><\/span><\/p>\n<ol>\n<li>Yoo MC, West JM, Eason JD,Vanatta JM.
