Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Subjects who are required to undergo transesophageal echocardiography according to the current clinical practice standards will be eligible for enrollment. Subjects will be screened for enrollment in this study against the inclusion and exclusion criteria. After successful screening and enrollment of subjects, the investigators will first use the investigational device to conduct transthoracic echocardiography (TTE), followed by transesophageal echocardiography (TEE). TEE will be conducted after the subject has been anesthetized. To avoid any delay in diagnosis and treatment, after the scan with the investigational device is completed, the probe will be reserved and the console will be switched to the existing commercial cardiac diagnostic ultrasound device in the study site for intraoperative guidance. In the study, each investigator will evaluate the overall image quality, user interface, workflow, user preferences, product preset, and functions of the system, as well as the device's safety and stability and fill out a user feedback questionnaire provided by the Sponsor.
