BACKGROUND: The clinical spectrum of Brucella infection is quite diverse and characterized by multi-system involvement. Patients present with myocarditis, endocarditis, or pericarditis. Infective endocarditis is the most common cardiovascular complication in patients with brucellosis. Although conduction abnormalities are seen in cases with endocarditis, they are reported very rarely in the setting of cardiac Brucella infection. CASE REPORT: An eight and a half-year-old male patient was referred to our clinic due to inadequate response to cotrimaxazole plus streptomycin treatment at the 15th day of admission...

BACKGROUND: Congenital complete heart block is a life-threatening condition which is highly associated with autoimmune and connective tissue disorders. Presence of maternal autoantibodies for associated conditions increases the risk of delivering a child with congenital complete heart block, however, less than a half of all women with such antibodies are symptomatic even after delivery. Mortality rate is highest during the neonatal period (45 %) and about two-thirds of all cases will require permanent pacing at some point in their lives...

BACKGROUND: The subcutaneous implantable cardioverter-defibrillator (S-ICD) is a novel implanted defibrillator for the prevention of sudden cardiac death that avoids intravascular access. Use of this device is limited by its inability to provide backup pacing. Combined use of the S-ICD with a permanent pacemaker may be the optimal choice in certain situations though experience with the use of both devices together remains limited. METHODS: We reviewed our single center experience with the S-ICD from March 2011 to November 2015...

Sinoatrial nodal cells (SANCs) generate spontaneous action potentials (APs) that control the cardiac rate. The brain modulates SANC automaticity, via the autonomic nervous system, by stimulating membrane receptors that activate (adrenergic) or inactivate (cholinergic) adenylyl cyclase (AC). However, these opposing afferents are not simply additive. We showed that activation of adrenergic signaling increases AC-cAMP/PKA signaling, which mediates the increase in the SANC AP firing rate (i.e., positive chronotropic modulation)...

BACKGROUND: Cupriavidus gilardii is an aerobic, Gram-negative, glucose-nonfermenting rod that was first identified in 1999. Because of the difficulty in accurate species identification of C. gilardii, there are few case reports of infection caused by this organism. In previous reports, C. gilardii has been characterized as an organism with low pathogenicity that causes opportunistic infections. CASE PRESENTATION: We encountered a case of pacemaker-associated bloodstream infection caused by C...

OBJECTIVES: Transcatheter aortic valve-in-valve implantation (ViV) is a new treatment for failing bioprostheses (BP) in patients with high surgical risk. However, comparative data, using standard repeat surgical aortic valve replacement (redo-SAVR), are scarce. We compared outcomes after ViV with those after conventional redo-SAVR in two European centres with established interventional programmes. METHODS: In-hospital databases were retrospectively screened for patients ≥60 years, treated for failing aortic BP...

There has been a significant increase in the number of patients receiving cardiovascular implantable electronic devices (CIED) over the last two decades. CIED infection represents a serious complication after CIED implantation and is associated with significant morbidity and mortality. Recently, newly advanced technologies have offered attractive and suitable therapeutic alternatives. Notably, the leadless pacemaker and anti-bacterial envelope decrease the potential risk of CIED infection and the resulting mortality, when it does occur...

PURPOSE OF REVIEW: Inflammatory mediators can interfere with cardiovascular system. This article describes some recent findings in this field. RECENT FINDINGS: In septic cardiomyopathy, direct and indirect interactions of endotoxin with the pacemaker current contribute to cardiac autonomic dysfunction and inadequately high heart rate, worsening prognosis. In myocardial infarction, inflammatory blood cells correlate with impaired coronary microvascular reperfusion...

BACKGROUND/OBJECTIVES: Muscular dystrophies are genetic muscle disorders, in which heart involvement and chronic respiratory impairment affect survival. Cardiac conduction disturbances require implantable cardiac pacemaker. Implantable defibrillators may also be necessary to prevent cardiac sudden death. The safety and risk of cardiac electronic devices' implantation are not known in patients with muscular dystrophy. We aimed to assess the risks related to cardiac implantable electronic devices (CIED) in muscular dystrophy patients ventilated by tracheostomy...

A previously stable 77-year-old man with significant cardiac history underwent an uneventful extraction of a Citrobacter-infected and eroded pacemaker lead. His postoperative course was acutely complicated by respiratory failure and quickly progressed into disseminated intravascular coagulation, acute renal failure, shock liver, and ventricular tachycardic arrest. I believe that this is the first case report of such a drastic turn of events after a routine pacemaker lead extraction.

Complete hardware removal is recommended in the case of patients with cardiovascular implantable electronic device (CIED) infections. However, the complete extraction of chronically implanted leads is not always achieved. The outcomes and optimal management of CIED infections with retained material after lead extractions have not been elucidated. In this case report, we present five patients with CIED infections with remnant lead tips even after lead extractions. Two patients had localized pocket infections, and were managed with antibiotics for a period of more than two weeks...

A 77-year-old woman presented with a 3-week history of low grade fever, appetite loss and dizziness. An electrocardiogram showed complete heart block. Echocardiography demonstrated severe aortic valve stenosis and a mass of probable vegetation 2 cm in diameter on the atrioventricular septum in the right atrium (RA), but no obvious intra-cardiac fistula. There was no growth of organism in blood cul tures. In the 4th week after admission, a harsh and continuous cardiac murmur was detected for the 1st time. Portable echocardiography revealed disappearance of the mass in the RA, and showed an intra-cardiac shunt from the left ventricle( LV) to RA...

BACKGROUND Cardiac resynchronization therapy (CRT) has been demonstrated to reduce morbidity and mortality in patients with advanced, drug-refractory heart failure. Procedure-related mortality is less than 1% in larger studies. Approximately10% of CRT patients have to undergo surgical revision because of infections, dislocations, or unacceptable electrical behavior manifested as high threshold, unstable sensing, or unwanted phrenic nerve stimulation. CASE REPORT A 70-year-old man with symptomatic congestive heart failure underwent implantation of a biventricular pacemaker on the left anterior chest wall in 2003 and pulse generator exchange in August 2009...

AIMS: Pocket haematoma is a common complication after defibrillator [implantable cardioverter defibrillator (ICD)] implantation, which is not only painful, but also increases the risk of device-related infection, and possibly embolic events. The present study seeks to evaluate the rate and predictors of clinically significant pocket haematoma. METHODS AND RESULTS: This study included 2500 patients receiving an ICD in the SIMPLE trial. A clinically significant pocket haematoma was defined as a haematoma that required re-operation or interruption of oral anticoagulation (OAC) therapy...

BACKGROUND Infections following cardiovascular implantable electronic device (CIED) procedures, including pacemaker and implantable cardioverter-defibrillators, are devastating and costly. Preimplantation prophylactic antimicrobials are effective for reducing postprocedural infections. However, routine postprocedural antimicrobials are not associated with improved outcomes, and they may be harmful. Thus, we sought to characterize antimicrobial use patterns following CIED procedures. DESIGN All patients who underwent CIED procedures from October 1, 2007 to September 30, 2013 and had procedural information entered into the VA Clinical Assessment Reporting and Tracking (CART) software program were included in this study...
