Permanent cardiac pacing after open-heart surgery: acquired heart disease
Insights
Permanent cardiac pacing is required in 2.1% of open-heart surgery patients. Key risk factors include pre-existing conduction issues, advanced age, aortic calcification, and specific valve surgeries, impacting patient morbidity.
Area of Science:
- Cardiovascular Surgery
- Cardiac Electrophysiology
- Medical Device Technology
Background:
- Open-heart surgery for acquired heart disease can necessitate postoperative cardiac pacing.
- Understanding predictors of permanent pacemaker implantation is crucial for patient management.
- The incidence and associated factors of permanent pacing post-cardiac surgery require detailed analysis.
Purpose of the Study:
- To identify the incidence of permanent cardiac pacing after open-heart surgery.
- To determine the key risk factors associated with the need for postoperative permanent pacing.
- To evaluate the impact of permanent pacing on patient morbidity.
Main Methods:
- Retrospective review of 5,942 patients undergoing open-heart surgery for acquired heart disease.
- Analysis of patient data to identify those requiring permanent cardiac pacing postoperatively.
- Statistical evaluation to determine significant risk factors and complications.
Main Results:
- 123 patients (2.1%) required permanent cardiac pacing postoperatively.
- Higher incidence in patients undergoing valvular surgery (4.6%) compared to coronary bypass (0.6%).
- Significant risk factors identified: preoperative conduction disorder, advanced age, aortic annular calcification, tricuspid valve surgery, and inadequate myocardial protection.
Conclusions:
- Permanent pacemaker implantation is a notable complication of open-heart surgery, particularly after valvular procedures.
- Preoperative conduction abnormalities, patient age, aortic calcification, specific valve surgeries, and myocardial protection quality are critical determinants.
- Postoperative pacing significantly contributes to patient morbidity, with lead-related issues being common complications.
Abstract:
Retrospective review of 5,942 patients who underwent open-heart surgery for acquired heart disease revealed that 123 patients (2.1%) required permanent cardiac pacing postoperatively; 4.6% of these underwent predominantly valvular surgery and 0.6% had coronary bypass. The most important factors appeared to be: 1) preoperative evidence of a conduction disorder; 2) advanced patient age; 3) dense calcium in the aortic annulus; 4) valvular surgery and, especially, tricuspid valve surgery; and 5) poor myocardial protection. Postoperative permanent pacing had a considerable impact on patient morbidity from maintenance operations; most complications were lead-related problems.
