INTRODUCTION    Cardiac device infections (CDI) are still a significant problem. The knowledge of risk factors for CDI is crucial both for preventing infections and reducing mortality. OBJECTIVES    The assesment of the risk factors and long term survival of patients with CDI. PATIENTS AND METHODS    The clinical data of 1837 patients (40.9% CDI) undergoing transvenous leads extraction (TLE) at a single institution from 2006 to 2015 was analyzed. We compared the clinical and procedure-related factors for all types of CDI: isolated pocket infection (IPI), isolated lead-related infective endocarditis (ILRIE) and PI+LRIE...

Infections involving internal cardiac devices can be very challenging to treat, and almost universally require complete device extraction for successful management. Of the pathogens that cause device-related endocarditis, fungi such as Candida albicans are notoriously difficult to manage because of their propensity to produce large vegetations and the need for long-term treatment with potentially toxic medications. Furthermore, individuals who develop fungal, device-associated endocarditis are typically among the most complex patients, with significant comorbidities that place them at high risk for open heart procedures such as surgical device extraction...

Right-sided infective endocarditis (RSIE) is less common than left-sided infective endocarditis (IE), encompassing only 5-10% of cases of IE. Ninety percent of RSIE involves the tricuspid valve (TV). Given the relatively small numbers of TVIE cases operated on at most institutions, the purpose of this review is to highlight and discuss the current understanding of IE involving the TV. RSIE and TVIE are strongly associated with intravenous drug use (IVDU), although pacemaker leads, defibrillator leads and vascular access for dialysis are also major risk factors...

BACKGROUND: Carvajal syndrome is an autosomal dominant or autosomal recessive disorder, manifesting with dilated cardiomyopathy, woolly hair, and palmoplantar keratoma. Additional manifestations can be occasionally found. Carvajal syndrome may be due to mutations in the desmocollin-2, desmoplakin, or plakophilin-2 gene. METHODS AND RESULTS: We report a family with Carvajal syndrome which additionally presented with hypoacusis, noncompaction, recurrent pharyngeal infections, oligodontia, and recurrent diarrhoea...

Defibrillation can be successfully provided by the subcutaneous implantable cardioverter defibrillator (ICD) without the leads. In contrast, traditional ICDs require leads that can cause central venous stenosis, lead-induced endocarditis, and carry the risk of tricuspid regurgitation by valve adhesion, perforation, coaptation interference, or entanglement. Central venous stenosis, infection, and tricuspid regurgitation are all critically important considerations in hemodialysis patients. Recent reports are supporting the use of subcutaneous ICDs in renal patients maintained on long-term hemodialysis...

BACKGROUND: Many patients with severe heart failure (HF) have an indication for baroreflex activation therapy (BAT) and an ICD. Concerns about device-device interactions were addressed in a study with small sample size that concluded combined BAT and ICD therapy is safe. There are no published data, however, concerning device-device interactions between BAT and a subcutaneous ICD (S-ICD). Since BAT frequently interferes with surface ECG recordings there are doubts about compatibility of BAT and S-ICD devices...

Cardiac surgery patients with infected implantable cardioverter defibrillator hardware face high morbidity with both surgical and nonoperative management options. We present a case of infected epicardial patch defibrillator leads in a patient with prohibitively high risk of death with open surgical removal. As a less morbid alternative, an Eloesser flap was used to convert his presenting mediastinal empyema necessitans into a chronic, manageable wound.

This case series reports our early experience with a minimally invasive percutaneous method of safely removing large vegetations during lead extraction in septic cardiac implantable electronic devices (CIED). Debate exists concerning the management of vegetations involving these devices. Lead extraction is mandated for infections, but vegetations may embolize, causing complications. Surgical debridement is recommended; alternatives include cardiopulmonary bypass, minimally invasive thoracotomy, or transatrial approaches...

There have been many evolutionary milestones in cardiac implantable electronic device (CIED) therapy over the past few decades. These advancements have created new  challenges. Right ventricular pacing was the original (late 1950s) breakthrough, however the risk of pacing induced dyssynchrony has become evident. Biventricular pacing provided a viable way to mitigate dyssynchrony, but only benefits certain patients (primarily left bundle branch block and QRS duration ≥150 ms with depressed left ventricular (LV) function)...

A 59-year old heart transplant recipient was admitted due to continuous pain in her left axilla. A purulent collection was found at the site of prior defibrillator placement, where a remnant proximal segment of an electric lead was found. Two years before, the patient had had pocket infection treated with revision, but without device extraction. The remnant lead was eventually removed transvenously without complications. This is the first description of infection complicating retention of lead fragments after heart transplant...

BACKGROUND: In the first 24h after pacemaker or implantable cardioverter/defibrillator (ICD) implantation or replacement, the occurrence of hematoma and pain in the surgically treated region is not infrequent and may result in re-intervention and/or more severe complications, such as infections. Currently, the post-implant phase management is very empiric. The aim of this study was to test the clinical applicability and usefulness of an external close-circuit cooling system for the management of the early post-implant period in patients with high risk of hematoma due to anticoagulant and/or antiplatelet therapy...
