Perioperative outcome of left atrial appendage amputation in coronary artery bypass grafting.

Background: Left atrial appendage (LAA) amputation performed alongside cardiac surgery has become an increasingly established procedure to reduce stroke risk in patients with atrial fibrillation. As the recommendation levels for LAA amputation continue to rise, ample evidence assessing its perioperative safety and risk factors is of utmost interest.

Methods: All patients who underwent isolated coronary artery bypass grafting (CABG) between 2018 and 2021 at two high-volume centers were retrospectively included in the study.

Off-pump coronary artery bypass grafting with clampless aortic anastomosis devices: Aortic sealing devices versus automated anastomosis punching.

Objectives: Clampless aortic anastomosis devices aim to lower stroke risk in off-pump coronary artery bypass grafting. Two main strategies for clampless anastomosis devices emerged with automated anastomosis punching and aortic sealing devices, prompting the question of perioperative outcome differences.

Methods: All consecutive patients undergoing elective off-pump coronary artery bypass grafting with a clampless aortic anastomosis device between September 2014 and December 2021 in 2 centers were retrospectively included.
