What is indication for transesophageal echocardiography?

Transesophageal echocardiography (TEE) is primarily indicated for detailed imaging of cardiac structures when transthoracic echocardiography is inadequate. It is commonly used to assess conditions such as suspected cardiac thrombi, evaluate prosthetic heart valves, and investigate potential sources of embolism. TEE is also valuable in preoperative assessments and during certain procedures, such as catheter ablations or cardioversion, to provide real-time visualization. Additionally, it can help diagnose congenital heart defects and evaluate aortic pathology.
