Conduction Disorders After Sutureless Aortic Valve Replacement [1]
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.
