transthoracic echocardiogram
Also written as: TTE — transthoracic echocardiogram
A non-invasive ultrasound examination of the heart performed by placing the probe on the chest wall.
Full Definition
A transthoracic echocardiogram (TTE) is the standard non-invasive cardiac imaging modality that uses ultrasound waves transmitted through the chest wall to visualize cardiac structures and assess function. TTE provides real-time imaging of cardiac chambers, valves, and blood flow patterns, making it essential for diagnosing and monitoring various cardiovascular conditions. The procedure is performed with the patient in left lateral decubitus position, using multiple acoustic windows including parasternal, apical, and subcostal views. In medical literature, editors must distinguish this from transesophageal echocardiogram (TEE) and ensure proper abbreviation usage.
Usage
Usage note: Distinguish clearly from TEE (transesophageal echocardiogram). Use TTE abbreviation after first mention.
