NCT02919124

Brief Summary

The aim of this study is to evaluate whether use of the echoclip device (an ultrasound transducer positioning device which can stabilize the involved part of the myocardium on the beating heart) facilitates imaging of coronary bypass anastomoses during coronary bypass surgery. A total of 100 low risk patients undergoing elective on-pump coronary bypass surgery will be included in the study in order to evaluate if the surgeons can visualize the coronary anastomoses before closure of the sternum. Ultrasonograpic pictures will be analyzed directly peroperatively and electronically post-operatively in order to evaluate if selected areas of the anastomoses can be visualized. Use of the echoclip devise will be considered a success if at least 80% of the anastomoses can be visualized.

Outcome Measures

Primary Outcomes (1)

  • Quality of periferal coronary artery bypass anastomotic structures

    Ultrasonographic images of periferal coronary artery bypass anastomoses will be studied in order to evaluate if the area of anastomotic structures from various locations of the anastomoses (heel, central portion and the to toe) can be visualized directly on the screen using the echoclip device.

    Peroperative

Secondary Outcomes (1)

  • Automatic quality control of periferal coronary artery bypass anastomotic structures

    Peroperative

Study Arms (1)

Echoclip device

EXPERIMENTAL

Ultrasonography using the echoclip device

Device: Echoclip

Interventions

EchoclipDEVICE

An ultrasound transducer positioning device, the Echoclip device (Aalborg Hospital, Aalborg,Denmark), which can stabilize the involved part of the myocardium on the beating heart, keep the gel at place, and position the ultrasound transducer correctly for imaging will be used for visualising the coronary bypass anastomoses during surgery
