Is it necessary to have an esophageal echocardiogram?
Transesophageal echocardiography is generally necessary.
Transesophageal echocardiography involves inserting a probe into the esophagus, advancing it to the back of the heart, allowing detailed assessment for cardiac abnormalities. Compared with conventional echocardiography, this method provides clearer images and enables more accurate diagnosis. However, this procedure can be quite uncomfortable for patients, so adequate psychological preparation is essential before undergoing the test. Because the esophagus lies close to the heart and there is no interference from the lungs, transesophageal echocardiography produces high-resolution images, particularly useful for evaluating the left atrial appendage and detecting the presence or absence of thrombus. This information is critical before proceeding with further treatments. If a thrombus is detected, anticoagulation therapy for four weeks is required before attempting cardioversion or radiofrequency ablation. If no thrombus is found, surgery can proceed within 24 hours. Therefore, transesophageal echocardiography not only identifies thrombi in the left atrial appendage but also detects atypical atrial septal defects.
Patients are advised to remain calm and relaxed before the examination, as excessive anxiety or stress may cause tachycardia, potentially affecting the accuracy of echocardiographic results.
