Paradoxical restoration from complete and persistent atrioventricular block after surgical aortic valve replacement: a case report.

Background: One of the most important and relatively frequent complications of aortic valve replacement is atrioventricular block. It typically occurs by direct injury of the infranodal conduction system due to intra-operative manipulation and persists post-operatively, necessitating permanent pacemaker implantation in many cases.

Case Summary: A 66-year-old man presented to our hospital after experiencing syncope while walking after drinking.
