Objective To explore the clinical efficacy of two different aortic proximal anastomotic strategies: Heartstring device (HS) and partial clamping (PC) during off-pump coronary artery bypass grafting (OPCAB).
Methods Clinical data of 258 patients who underwent OPCAB procedure at the Department of Cardiovascular Surgery, Zhongshan Hospital, Fudan University from May 2018 to May 2021 were retrospectively analyzed, including 220 males and 38 females, with a mean age of 68.6±8.2 years. Patients were grouped according to different intraoperative aortic manipulation strategies: Heartstring clampless facilitating device group (HS, n=86) and partial clamp group (PC, n=172).
Results There were two cases of postoperative death (0.78%, one case in each group), and there were 7 cases of postoperative stroke 7 (2.13%; 1 in the HS group and 6 in the PC group, P=0.430).
Conclusions The Heartstring proximal anastomosis device can reduce aortic operation, and good short-term effects can be obtained for high-risk patients.
