It depends. If the patient has been on a blood thinner for at least 4 weeks then most of the time, it is not necessary. However if the patient is not on a blood thinner, then tee is recommended to detect clot (s) in the heart.
Not neccessary. For pts on anticoagulation for 6 to 8 wks the chances of cardiac source of emboli and cva is low. If its shorter than this a tee would be needed to rule out a clot in the left atrial apendage.
TEE. Transesophageal echocardiogram is modality where ultrasound equipped probe is introduced in the esophagus to get a better view of the valvular anatomy of the heart, looking for specifically vegetations/emboli.
TEE. In a tee the transducer is passed into the throat down into the esophagus. A tee uses sound waves to produce images of your heart. It is used in management of patients in whom transthoracic images are inadequate. It creates ultrasound images of heart structures including the heart muscle itself as well as valves. Doppler waves evaluate blood flow throughout the heart.
TEE. Tee is done under sedative meds which let you not remember the procedure. The back of the throat is numbed and a tube is placed through your mouth and down the esophagus which runs behind the heart. Ultrasound pictures are taken to view the heart in detail. Usually done for looking at the valves, ruling out blood clot in the heart, or looking at "holes in the heart". Lasts about 30 min.
Procedure. A tee is a procedure done under sedation where an ultrasound probe is inserted through the mouth into the esophagus and images are obtained of the heart.
