Key result
A novel two-suture technique for left atrial appendage occlusion during CABG was as effective as a purse-string suture, with 3.3% recanalization in both groups (p>0.05).
Why the study?
The study aimed to optimize the surgical technique for left atrial appendage occlusion in patients with atrial fibrillation during coronary artery bypass grafting.
Does a two-suture technique for LAA occlusion prevent LAA recanalization compared to a purse string suture in patients with atrial fibrillation during CABG?

Does a two-suture technique for LAA occlusion prevent LAA recanalization compared to a purse string suture in patients with atrial fibrillation during CABG?
A novel two-suture technique for epicardial LAA occlusion during CABG is as effective as the traditional purse-string suture for preventing recanalization.

Novel two-suture LAA closure during CABG may enhance occlusion in AF; hypothesis-generating and requires larger trials before adoption.
Aim. To optimize the surgical technique for left atrial appendage (LAA) occlusion in patients with atrial fibrillation (AF) during coronary artery bypass grafting. Material and methods. The study included 60 patients with atrial fibrillation (AF). The patients were randomly divided into 2 groups. In the first group of patients, LAA was closed using the developed two-suture technique. In patients of the second group, a purse string suture was applied to the LAA. All patients underwent transesophageal echocardiography (TEE) before surgery to rule out the presence of intracardiac blood clots. To assess the effectiveness of the method in the postoperative period, TEE was performed. Results. According to postoperative TEE, one case of LAA recanalization in each group was revealed (p>0,05). In the second group, the residual LAA cavity after applying a purse string suture was revealed. During the follow-up period, there were no neurological complications and deaths. Conclusion. According to the study results, it was found that the proposed two-suture technique for LAA occlusion is not less effective than the purse-string suture. The developed technique of two-suture epicardial occlusion of LAA showed actual technical advantages, allowing to optimize this surgery in different categories of patients.

Vecherskiy et al. (2020) conducted an RCT in Atrial fibrillation during coronary artery bypass grafting (n=60). Two-suture technique for left atrial appendage occlusion vs. Purse string suture was evaluated on Left atrial appendage recanalization (p=>0.05). A novel two-suture technique for left atrial appendage occlusion during CABG was as effective as a purse-string suture, with 3.3% recanalization in both groups (p>0.05).
