Wound area is covered with Hemopatch just beneath the venous anastomosis (arrow). C. A second Hemopatch is positioned around the venous anastomosis, with hemostasis achieved while the coronary flow is established. Full flow can be seen in the venous anastomosis (compare with B, where it is flaccid).
