Conduction Disorders After Sutureless Aortic Valve Replacement

This single center retrospective study analyzed the incidence of permanent pacemaker requirement in 108 consecutive patients undergoing sutureless aortic valve replacement with the Perceval S bioprosthesis.  In-hospital postoperative pacemakers were required in 23% of patients, 3 times the rate reported in earlier studies and approximately 6 times the historical rate following a standard surgical AVR.
