A study demonstrated that the type of surgical approach utilised is the key factor for determining lead survival.10 A median sternotomy is preferred as it provides excellent visualisation and relative ease of implantation of pacemaker leads. However, patients with congenital heart disease undergoing multiple surgeries have extensive scar tissue which complicates the procedure.
There have been case reports of listeria prosthetic valve endocarditis; however, there is paucity of literature on listeria-related pacemaker lead infection.
A normal plain film of the chest immediately after pacemaker implantation, the close proximity of the pacemaker lead to the orifice of the pseudocyst, and the histopathological findings are all highly suggestive that repetitive mechanical trauma of the pericardium by the perforated atrial pacemaker lead caused fibrinous pericarditis followed by an inflammatory pericardial pseudocyst.
Venous obstruction often first becomes apparent during pacemaker lead revision, when difficulty in passing the new pacing lead is encountered.
There is an acute angle between the CS ostium and the tricuspid valve, which complicates pacemaker lead implantation; therefore, the ventricular lead should be looped in the RA to enter the right ventricle.
A 0.035-inch angled tip hydrophilic guidewire was stepwise navigated through the tortuous midline u-shaped segment of the collateral vein and crossed over to the right side and from here at an acute angle via the right IV, along the pacemaker leads into the inferior vena cava (Figure 2).
Our research focused on comparing different pacemaker lead positions in the right ventricle, regarding its influence on the functional status in the patients who had the preserved left ventricular function at the beginning of the study and also after 12 months in real life circumstances.
Disseminated Mycobacterium chelonae infection causing pacemaker lead endocarditis in an immunocompetent host.
"Now we have pacemakers that are so small--not much larger than an antibiotic pill--they can be attached directly to the inside of the heart, all the problems related to the old-fashioned pacemaker lead are abolished."

Deaths and cardiovascular injuries due to device-assisted implantable cardioverter-defibrillator and pacemaker lead extraction.
Since the MRI scanner employs the use of very powerful magnets, the scans can be dangerous for patients with a pacemaker, defibrillator, permanent pacemaker lead, certain artificial joints, and other implanted metal devices.
