Pacemaker lead infections are rare but potentially life threatening. We report the case of an 80-year-old pacemaker-dependent female patient with complete heart block, who presented with subfebrile temperatures and chills due to a pacemaker lead infection by Enterococcus faecalis.

Background: Transvenous lead extraction (TLE) has become an essential component of lead management strategies, but it carries the risk of severe complications, including damage to the tricuspid valve. Currently, there are no established predictors that can help prevent these complications.
Case Summary: An 84-year-old male with a dual-chamber pacemaker was admitted to the hospital due to a pocket fistula resulting from a local infection.

Superior vena cava (SVC) syndrome is a result of impaired blood flow from the SVC to the right atrium, leading to venous congestion in the head and neck. It can be caused by clotting disorders or compressive tumors of the head and neck but has become more prevalent in the setting of implantable devices such as pacemakers. As such, managing these patients can present challenges for physicians who have to account for SVC syndrome as well as their underlying condition requiring an implantable cardiac device.

Direct pacing of the mid myocardium where re-entry originates can be used to prevent ventricular arrhythmias and circumvent the need for painful defibrillation or cardiac ablation. However, there are no pacing electrodes small enough to navigate the coronary veins that cross these culprit scar regions. To address this need, we have developed an injectable ionically conductive hydrogel electrode that can fill the epicardial coronary veins and transform them into flexible electrodes.

Background: Transvenous pacemakers (TVP) and leadless pacemakers (LP) are two reliable permanent modalities for the treatment of heart rhythm disorders. Several observational studies explored the safety and efficacy of the two devices. The aim of this meta-analysis study is to present a comparative analysis of the safety of leadless versus transvenous pacemakers.

Implanting pacemakers in patients with isolated persistent left superior vena cava (PLSVC) present unique challenges. Recognizing venous anomalies and adapting lead placement techniques are crucial for successful outcomes and stable pacemaker function.
