Transesophageal echocardiography in dogs
21 May 2018 – News
Transesophageal echocardiography (TEE) is a semi-invasive technique that enables direct visualization of the heart and other anatomic structures through the esophagus. TEE provides better quality images than routine transthoracic echocardiography as there is less interference from surrounding structures.
The procedure has several practical applications as it can be used not only as a diagnostic instrument but also as a monitoring device for animals undergoing surgery and critically ill patients.
It is can also be used to measure anatomic structures and to guide procedures, including patent ductus arteriosus closure, balloon valvuloplasty, septal defect occlusions and heartworm extraction surgery.
The TEE probe should always be lubricated and introduced/removed carefully in the unlocked position to prevent complications. It should not be used in animals with swallowing difficulties, with esophageal conditions. Please manipulate the probe carefully if it has no overheating safety mechanism.
