Surgical technique modifies the postoperative atrioventricular block rate in sutureless prostheses.

Background: The main objective was to analyse the impact of the modification of the Perceval S implantation technique on the prevalence of postoperative atrioventricular block, which requires a permanent pacemaker, in our aortic valve replacement series. In addition, we attempted to identify those risk factors that are related to the appearance of this complication.

Methods: Five hundred and seventy-two valve replacements were carried out with PERCEVAL S in our centre up to July 2018.
