Approximately half of the deaths directly related to a heart rhythm disorder management (HRDM) procedure were among patients undergoing device implantation procedures, with cardiac tamponade being the most common cause of death. This according to a retrospective study of 48,913 patients undergoing HRDM procedures between January 2000 and November 2016 at the Mayo Clinic. Patients from all 3 tertiary academic centers were included. Researchers found:
- Patients (mean age 65.7 years, 64% male) underwent a total of 62,065 HRDM procedures.
- Overall mortality and cerebrovascular event (CVE) rate was 0.36% and 0.12%, respectively.
- Among patients undergoing HRDM procedures, 48% of deaths directly related to the HRDM procedure were among patients undergoing device implantation procedures.
- Overall, cardiac tamponade was the most frequent direct cause of death (40%); infection was the most common indirect cause of death (29%).
- Overall 30-day mortality rate was 0.76%.
