Transesophageal echocardiography is a diagnostic test conducted to create a clear image of heart muscles and different parts of the heart. The test is carried out using an ultrasound, that is passed into esophagus of the patient.
Transducer, a device with a tube is passed into esophagus through throat. The transducer produces ultrasound waves which touch the heart and its parts. Reflected waves from heart are carried by transducer and are converted into an image by mechanical transformation. Standard ultrasound techniques are used to get an image of two dimensional slices of the heart. doppler evaluation of heart sound is possible with Transesophageal echocardiography.
purpose of Transesophageal echocardiography:-
Using Transesophageal echocardiography
* size of the heart
* pumping capacity
* myocardial tissue damage
* any abnormal tissue growth in heart valves can be assessed with image.
* different parts of heart such as aorta, pulmonary artery, both atrium and ventricles, tricuspid valve, bicuspid valve, semilunar valves, can be evaluated along with clear image, using transesophageal echocardiography.
preparing for transesophageal echocardiography:-
* fasting by patient for last 8 hours of procedure,
* explain the procedure to patient,
* an anesthetizing agent is given orally to patient to induce sedation in the tract where transducer tube is passed, i.e esophagus.
Do not to consume alcohol before the day of procedure and day of procedure to avoid imbalanced echocardiography results.
