Abstract
We evaluated the safety and feasibility of a new anastomotic device that simplifies coronary distal anastomosis during minimally invasive and robotically assisted coronary artery bypass graft surgery (CABG). Fourteen miniature pigs underwent off-pump CABG using bilateral internal thoracic arteries (ITA), namely, left ITA to left anterior descending artery and right ITA to right coronary artery. The device was used for distal anastomosis in a device group (n= 11), and conventional 7-0 polypropylene suture in a control group (n= 3). Graft flow was measured intraoperatively. One-month, 3-month, and 6-month postoperative angiography evaluations were done. Histopathologic examination of the anastomosis was also done. Baseline and intraoperative characteristics were similar in the two groups. There was no difference of anastomotic time between groups (p= 0.59). Graft flows werealso similar (p= 0.55), with good diastolic pattern in both groups. Angiography demonstrated FitzGibbon A patency in all anastomoses of both groups at each evaluation period. Histopathologic examination showed nonspecific inflammatory changes in the device group. The safety and feasibility of this anastomotic device for distal coronary anastomosis were shown in the swine model.
