Clinical Report: Pooled Rates of Permanent Pacemaker Implantation Following Commando and Hemi-Commando Surgical Interventions
Overview
This systematic review and meta-analysis determined the pooled rate of permanent pacemaker implantation following Commando and Hemi-Commando procedures, reporting a rate of 22.3%. The Chimney Commando modification was associated with a lower rate of 6.3%.
Background
The Commando procedure is a complex surgical intervention indicated for severe cardiac conditions, but it carries a risk of postoperative atrioventricular block necessitating permanent pacemaker implantation. Understanding the rates of pacemaker implantation is important for surgical decision-making. This analysis aims to provide estimates of the risks associated with different surgical techniques.
Data Highlights

Pooled Pacemaker Rate
95% CI
Commando
28.3%
21.2%–36.7%
Chimney Commando
6.3%
3.2%–12.1%
Key Findings
The pooled permanent pacemaker rate after Commando and Hemi-Commando procedures is 22.3%.
Substantial heterogeneity was observed (I² = 73.7%).
The Chimney Commando modification has a lower pacemaker rate of 6.3% compared to the traditional Commando procedure at 28.3%.
Sensitivity analyses confirmed the robustness of the findings.
Potential small-study effects were indicated by Egger's test (p = 0.0041).
Clinical Implications
The findings highlight the significant risk of permanent pacemaker implantation following Commando procedures, which should be considered in preoperative discussions. The Chimney Commando modification may offer a lower risk option for select patients, warranting further investigation in future studies.
Conclusion
The study provides insights into the rates of permanent pacemaker implantation following complex valve surgeries.
