Pacemaker need after sutureless aortic valve replacement: the role of the learning curve

Aim Aortic valve replacement (AVR) using sutureless prosthesis is a reasonable alternative in those patients with aortic stenosis who would benefit from reduced cross clamp time, such as elderly and high-risk patients. Actually, excellent performances have been demonstrated in hemodynamic outcomes and safety, but some questions remain open regarding long-term durability and the need for postoperative pacemaker implantation. Methods Between January 2014 and August 2019, all 436 patients [male 40.6%, median age 78 years interquartile range (73–82)] treated with sutureless AVR with a Perceval prosthesis were included in our analysis. Results The univariate logistic regression showed previous aortic valve surgery [P = 0.028; odds ratio (OR) 3.248], dialysis (P = 0.036; OR 6.435), renal insufficiency (P = 0.021; OR 2.75), EuroSCORE II (P = 0.016; OR 1.051) and year of operation (P
