epicardial echocardiography
Direct cardiac ultrasound imaging performed with the transducer placed on the heart surface during open-chest surgery.
Full Definition
Epicardial echocardiography involves placing ultrasound transducers directly on the heart surface during cardiac surgery to provide high-resolution imaging of cardiac structures and function. This technique offers superior image quality compared to transesophageal echocardiography for certain views and is particularly valuable for assessing valve repairs, detecting residual air, and evaluating ventricular function immediately after bypass separation. Epicardial imaging requires sterile transducer preparation and careful coordination between surgeon and echocardiographer to avoid interference with surgical procedures while obtaining diagnostic information.
Usage
Usage note: Distinguish from TEE by specifying direct heart surface contact and surgical field placement.
