Ultrasound scans of the heart can be performed either superficially on the chest or through the esophagus with long ultrasound probes. However, esophageal examinations pose daily challenges for cardiologists, as the ultrasound probe easily shifts due to natural muscle activities in the esophagus and movement from the heart and lungs. 

To counteract the probe’s movements, the cardiologist must either manually hold it against the movements of the esophageal muscles or stop the work momentarily to reposition the probe. At the same time, the cardiologist has to control the computer with ultrasound images and handle the ultrasound transducer itself. Therefore, the procedure requires three hands. 

The cardiologist often has to temporarily interrupt the procedure to reposition the probe, as image quality is crucial when the cardiologist navigates inside the heart. These interruptions extend the operation time and increase the risk of complications since patients are under general anesthesia. Furthermore, it leads to poor working postures and frustrating situations for the cardiologist, negatively affecting clinical work due to stress and an unsatisfactory working environment.
