Transvenous leads continue to be the standard means to deliver bradyarrhythmia and tachyarrhythmia device therapy. Risk factors for cardiac implantable electronic devices (CIED) infection or complications of transvenous lead extraction (TLE) and mortality represent a complex interplay between non-modifiable patient-related factors and actionable implant-related characteristics or adverse events. Careful attention to patient screening, infection mitigation, lead selection, and implant technique may enhance safety of the index procedure and subsequent clinical management.

This case details the successful implantation of a leadless pacemaker following the extraction of transvenous leads in a 72-year-old female patient with a complex cardiovascular history. The patient had undergone a series of cardiac interventions, including a recent percutaneous tricuspid valve repair with a metal clip implant due to severe regurgitation. After presenting with an infection at the pacemaker site, methicillin-resistant Staphylococcus hominis was identified, necessitating the removal of the entire pacing system.

Background: Globally, the number of cardiac implantable electronic devices (CIEDs) is increasing. In our study, we aimed to investigate whether CHADS-VASc and RCHADS-VASc scores are predictive of CIED-related complications.
Methods: Our investigation was carried out with a multicenter retrospective design.

Microelectrodes offer exceptional sensitivity, rapid response, and versatility, making them ideal for real-time detection and monitoring applications. Photoelectrochemical (PEC) sensors have shown great value in many fields due to their high sensitivity, fast response, and ease of operation. Nevertheless, conventional PEC sensing relies on cumbersome external light sources and bulky electrodes, hindering its miniaturization and implantation, thereby limiting its application in real-time disease monitoring.

Objective: To compare the paced QRS duration on different sites in age-, gender-, and indication-matched patients implanted with Micra leadless pacemakers and conventional transvenous pacemakers (TV-PM).
Method: A total of 82 patients from Xinhua Hospital, Shanghai Jiaotong University, were enrolled, including two groups of 41 patients matched according to gender, age, and pacemaker indications, who underwent Micra and TV-PM implantations, respectively. The baseline data of the patients, the pacing site described using three- and nine-partition methods, and the paced QRS duration on 12-lead electrocardiogram were then analyzed.
