Abstract:

Objective · To investigate risk factors for pocket-related complications in patients undergoing permanent pacemaker implantation after valvular surgery, as well as prevention and treatment strategies. Methods · The clinical data of 115 patients undergoing permanent pacemaker implantation after valvular surgery were collected. Postoperative pocket-related complications and the effects of long term administration of warfarin on them were retrospectively analyzed. Results · A total of 12 patients (10.43%) had pocket-related complications, including 8 cases (6.96%) of capsular hematoma and 4 cases (3.48%) of capsular infection or rupture. The average age of 12 patients at their first implantation was 66.5±7.1 years, among whom five are male (41.7%). For the warfarin group, 6 patients (9.23%) had capsular hematoma and 4 patients had capsular infection or rupture (6.15%). Conclusion · The incidence of pocket-related complications in patients undergoing permanent pacemaker implantation after valvular surgery is high. Long term administration of warfarin is a risk factor. Enhancing the awareness of pocket-related complications and prompt treatment can decrease the incidence of complications.
