Hypothesis
What are the predictors of the need for implantation of a permanent pacemaker and what are the long-term consequences of a postoperative pacemaker implantation?
Conclusion
The need for a permanent pacemaker after surgical aortic valve replacement is associated with increased postoperative complications and reduced long-term survival.
Supporting Evidence
- The need for PPM implantation was documented in 2.7% of the cases.
- Patients with a postoperative PPM had a higher comorbid burden and risk scores.
- The median survival decreased significantly for patients needing a PPM implant.
Takeaway
Some patients need a special heart device called a pacemaker after heart surgery, and this can mean they might not live as long.
Methodology
This is a retrospective file study analyzing 2500 patients who underwent surgical aortic valve replacement with a biological prosthesis.
Potential Biases
Potential bias due to the retrospective nature and the exclusion of patients with prior pacemakers.
Limitations
The study is retrospective, which may introduce bias, and many patients were elderly, limiting follow-up data.
Participant Demographics
Patients who underwent surgical aortic valve replacement from 1987 to 2017, with a mean age of 75.6 years for those needing a pacemaker.
