Postoperative permanent cardiac pacing was required in 2.1% of patients undergoing open-heart surgery, with higher rates in valvular (4.6%) than coronary bypass (0.6%) surgery.

What is the incidence and what are the risk factors for requiring permanent cardiac pacing after open-heart surgery for acquired heart disease?
Permanent cardiac pacing is required in 2.1% of patients after open-heart surgery, with higher rates in valvular surgery, and is associated with significant morbidity from lead-related complications.
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.
Goldman et al. (Tue,) conducted a observational in Acquired heart disease requiring open-heart surgery (n=5,942). Open-heart surgery was evaluated on Requirement for permanent cardiac pacing postoperatively. Postoperative permanent cardiac pacing was required in 2.1% of patients undergoing open-heart surgery, with higher rates in valvular (4.6%) than coronary bypass (0.6%) surgery.
