Efficacy of High-Resolution Epicardial Ultrasonography in Cardiovascular Surgery

In cardiovascular surgery, it is important to identify the target vessel and to assess the quality of vascular structure. Preoperative enhanced computed tomography (CT) and angiography give us that information; however, we sometimes encounter difficulties due to limitation of those preoperative examinations. Intraoperative use of 15-MHz high-frequency epicardial ultrasound with small probe has a great potential to detect small vessels and it will give us benefits in cardiovascular operations, especially coronary artery bypass surger
