BackgroundErosion of a pacer lead into the chest wall may result in pericardial effusion with cardiac tamponade. Free rupture into the pleura or mediastinum can result in hypotension and cardiac arrest.Case presentationWe report a unique case of a right ventricular pacer lead which eroded through the right ventricle into the left chest wall and pen...

Changes within the Coronary veins secondary to pacing leads have not been described, this study assessed these changes in explanted hearts. Macroscopically fibrous sheaths formed around longstanding leads, leading to slit like channels for venous return in smaller veins. Histologically changes included bland fibrosis, a foreign body response to the...

A high rate of malfunction, predominantly intermittent high-frequency artifacts (HFAs), has been recently reported in Abbott Medical Tendril pacing leads. To investigate the factors associated with the occurrence of HFAs on Tendril leads using a commonly used comparator lead for a control. We reviewed institutional data for Medtronic CapSureFix 507...
High and unstable capture thresholds affect the success rate of permanent His-bundle pacing (HBP). We aimed to introduce the modified techniques during different periods and the corresponding success rate of HBP implantation. Patients from a single centre who had intrinsic QRS

Cardiac resynchronization therapy (CRT) is an effective treatment for selected patients with heart failure, but it can be limited by the inability to place the left ventricular (LV) lead via the coronary sinus. The purpose of this study was to develop an alternative approach, placing the LV lead endocardially via an interventricular septal puncture...

Pacing lead-related tricuspid regurgitation (TR), a recognized complication of ventricular pacing lead implantation, may be affected by lead position or diameter. This study sought to determine the effect of ventricular pacing lead position and diameter on pacing lead-related TR. A randomized prospective trial compared pacing leads in the right ven...

The number of pediatric pacemakers implanted is still relatively small. Children requiring pacing therapy have characteristics that are distinct from those of adults, including physical size, somatic growth, and cardiac anomalies. Considering these features, long-term follow-up of pediatric pacemaker implantation is necessary. Selection of appropri...

We present a case of a migrated ventricular pacing lead after 1 month of implantation. Enhanced computed tomography allowed for the exact diagnosis. Defibrillator lead perforations are widely described. Although most pacemaker lead perforations are usually recognized during or shortly after implantation, late perforations can occur.

We report three cases of an unusual form of “reel syndrome” characterized by isolated, reeling dislodgement of a single lead in patients with dual-chamber or biventricular devices. One of these patients presented with worsening heart failure due to loss of left ventricular pacing and the others were detected incidentally during scheduled device che...
