To explore the echocardiographic features of coronary anastomotic leakage after Bentall operation, and summarize the key points of its diagnosis.

The echocardiographic features of 38 patients with coronary anastomotic leakage after Bentall operation diagnosed by echocardiography and confirmed by computed tomography angiography from January 2017 to December 2018 at Beijing Anzhen Hospital were retrospectively analyzed.

The echocardiographic features of coronary anastomotic leakage were as follows: Gaps could be observed at the anastomotic site of the coronary artery, with a mean size of (3.2±1.5) mm; shunt and high-velocity signal could be detected by color and continuous wave Doppler ultrasound at the anastomotic site, with a mean peak velocity of (349±108) cm/s; echo-free areas could be observed between the artificial and autologous aorta, with an average width of (11.9±10.1) mm; and a shunt between the aorta and right atrium could be found in some cases, with an incidence of about 10.5%.

Echocardiography can be a useful tool for diagnosis of coronary anastomotic leakage, and can provide important information such as the size, number, and hemodynamics of leakage.
