Final answer:
The right coronary artery (RCA) can be visualized in a transesophageal echocardiogram (TEE) using the long axis view. The RCA originates from the aorta and courses along the atrioventricular groove on the posterior surface of the heart.
Step-by-step explanation:
In a transesophageal echocardiogram (TEE), the right coronary artery (RCA) can be visualized using the long axis view. The long axis view is obtained by angling the ultrasound probe so that it provides a parallel view to the long axis of the heart. In this view, the RCA can be seen originating from the aorta and coursing along the atrioventricular groove on the posterior surface of the heart.
