چکیده
Absorbable antibacterial envelopes mitigate risk of pocket infections during repeat cardiac implantable electronic device (CIED) procedures. Despite use envelopes, CIED infection persists. However, hallmark signs including incisional erythema, drainage, and wound dehiscence overlap with a less common clinical entity – allergic reaction. To present case recurrent secondary to an inflammatory response the envelope proven histological evaluation. N/A A 52-year-old male remote aortic valve replacement complicated by complete heart block dual chamber pacemaker (DC PPM) underwent generator change Tyrx pouch. One week later, he developed partial cloudy drainage. The patient was started on antibiotic therapy percutaneous system extraction placement externalized right ventricular lead. Pocket cultures were negative. contralateral DC PPM inserted completed course antibiotics. Within two weeks placement, presented dehiscence. new removed pathologic specimen obtained from presumably infected pacing lead placed. Cultures again demonstrated foreign body lymphoplasmacytic focal neutrophilic inflammation most consistent implantation low-lateral left-sided distant prior site without envelope. discharged antibiotics no evidence or at over follow up period 6-months. Allergic reaction should be considered dehiscence, particularly if recurrent. Tissue biopsy can elucidate mechanism.

Cardiac Implantable Electronic Device Infection: From an Infection Prevention Perspective
A cardiac implantable electronic device (CIED) is indicated for patients with severely reduced ejection fraction or with life-threatening cardiac arrhythmias. Infection related to a CIED is one of the most feared complications of this life-saving device. The rate of CIED infection has been estimated to be between 2 and 25; though evidence shows that this rate continues to rise with increasing e...

Infective endocarditis and the pacemaker: cardiac implantable electronic device infection.
We are seeing more implantation of cardiac device such as pacemakers and defibrillators and also cardiac implantable electronic device infection. The infection may affect just the pocket site or progress to deeper infection and bacteraemia. Inadequately treated infection may lead to right sided endocarditis, cardiotomy for pacemaker explantation and increased cost and length of stay in the hosp...
متن کاملReimplantation and Repeat Infection After Cardiac-Implantable Electronic Device Infections: Experience From the MEDIC (Multicenter Electrophysiologic Device Infection Cohort) Database.
BACKGROUND Infection is a serious complication of cardiovascular-implantable electronic device implantation and necessitates removal of all hardware for optimal treatment. Strategies for reimplanting hardware after infection vary widely and have not previously been analyzed using a large, multicenter study. METHODS AND RESULTS The MEDIC (Multicenter Electrophysiologic Device Infection Cohort)...

BACKGROUND Indications for cardiac implantable electronic devices (CIEDs) are increasing. Although CIED infections occur infrequently, the impact of this outcome is expected to be substantial. OBJECTIVE The purpose of this study was to the evaluate the outcome of patients undergoing removal of infected CIEDs. METHODS A retrospective study was conducted of all patients with proven or suspect...
