    The pooled permanent pacemaker rate after Commando and Hemi-Commando procedures is 22.3% based on 797 patients from 12 studies.

  • 2

    Subgroup analysis revealed the Chimney Commando modification has a significantly lower pacemaker rate of 6.3% compared to 28.3% for the traditional Commando procedure.

  • 3

    The systematic review included studies with a sample size of at least 5 patients and assessed permanent pacemaker implantation rates.

  • 4

    Sensitivity analyses confirmed the robustness of the findings, while Egger's test indicated potential small-study effects.

  • 5

    Future prospective comparative studies are needed to validate the preliminary findings regarding the Chimney technique's lower risk.
