Transesophageal sensors are intended for transesophageal ultrasound, when classical echocardiography is not possible: ribs, lungs, calcification, dentures, excess muscle mass and subcutaneous fat deposits can create acoustic obstructions on the path of the ultrasound beam. The introduction of the sensor through the esophagus provides an opportunity to thoroughly study the structure of the heart, in particular, the state of the implants, the structure of the left atrium and the aorta, identify defects, thrombi in the ear of the atria and neoplasms of unclear etiology, diagnose endocarditis and monitor surgical intervention. The device is inserted by an endoscopist. The procedure is reminiscent of gastroendoscopy, so the shape, size and principle of the sensor control resemble a gastrofibroscope. The working part of the device is equipped with a movable, rotating radiator, so that the operator receives a dynamic picture of what is happening. Modern models can perform three-dimensional scanning in real time, which is convenient during the operation. There are neonatal, children's and adult devices, which differ in size. To reduce the patient's discomfort, the session is conducted under anesthesia and lasts 5-15 minutes. TEE-sensors operate at a frequency of 3-8 MHz. Scanning is carried out at an angle of 90 degrees. The case near the device is sealed, waterproof.
Transesophageal echocardiography is prescribed in the following cases:
The procedure allows you to recognize at an early stage the majority of serious cardiological diseases, including chronic ones. Transesophageal ultrasound is improved year by year: manufacturers regularly update TEE sensors and diagnostic systems.
