Key result
Surgical extraction successfully resolves Chiari network entrapment of a tined atrial lead.
Why the study?
The Chiari network is usually clinically insignificant but can pose risks of complications during procedures such as pacemaker lead implantation.
Population
1 78-year-old woman with symptomatic 2:1 atrioventricular block

The Chiari network can cause pacemaker lead entrapment requiring surgical removal, highlighting the need for careful pre-procedural imaging and awareness during implantation.
Sakai et al. (2021) conducted a case report in Atrioventricular block with pacemaker lead entrapment (n=1). Surgical removal of entrapped pacemaker lead was evaluated on Successful removal of the entrapped lead. Surgical removal via thoracotomy and right atriotomy successfully extracted a tined J-shaped atrial pacemaker lead that had become entrapped in an undetected Chiari network.
