Abstract
Serratia marcescens is a gram-negative bacillus that is an opportunistic agent in respiratory tract infections, urinary tract infections, and septicemia. It is rarely a cause of infective endocarditis, but in cases of endocarditis, it follows a rapid and devastating course. A previously healthy female in her mid-50s presented with fever, abdominal pain, right lower extremity pain, and diarrhea. Blood cultures were positive for S. marcescens, and additional evaluation revealed infarction in the spleen and kidneys, raising concern for endocarditis with associated embolic phenomena. The patient was subsequently found to have an embolus in the right popliteal artery and underwent a right popliteal thromboembolectomy. Antimicrobial therapy with cefepime and gentamicin was begun. A transesophageal echocardiogram revealed a large, mobile mitral valve vegetation. Care was complicated by intracranial hemorrhage, and the decision was made to withdraw care. A review of the databases Embase and PubMed revealed 63 additional cases of S. marcescens endocarditis. Analysis of these cases demonstrated a preponderance of aortic and mitral valve involvement, not tricuspid valve involvement, despite a risk factor of intravenous drug use in over 60% of cases. Mortality was 50%, and sequelae such as congestive heart failure and renal insufficiency occurred in the majority of survivors. In conclusion, S. marcescens is a rare but devastating cause of endocarditis with a primary risk factor of intravenous drug use but with a predilection for left-sided valvular lesions, not right-sided lesions.

Abstract
Serratia species are facultative anaerobes, non-spore-forming, motile Gram-negative bacteria. Serratia spp. are currently thought to cause a variety of infections, such as bacteremia, urinary tract infections, and pneumonia, as well as other, less common infections, including ocular infections or skin and soft tissue infections. On the other hand, Infective Endocarditis (IE) is an infrequent disease with notable morbidity and mortality. Even though IE is rarely caused by Serratia spp., these infections can be quite problematic due to the lack of experience in their management. This study aimed to systematically review all published cases of IE by Serratia spp. in the literature. A systematic review of PubMed, Scopus, and Cochrane library (through 13th May 2021) for studies providing epidemiological, clinical, microbiological data as well as data on treatment and outcomes of IE by Serratia spp. was performed. In total, 50 studies, containing data for 72 patients, were included. A prosthetic valve was present in 18.1%. The mitral valve was the most commonly infected site, followed by the aortic valve. The diagnosis was facilitated by transthoracic echocardiography in 34.7%, while the diagnosis was set at autopsy in 22.4%. Fever, sepsis, and embolic phenomena were the most common clinical presentations, followed by heart failure. Aminoglycosides, cephalosporins, and carbapenems were the most commonly used antimicrobials. Clinical cure was noted only in 53.5%, while overall mortality was 47.2%. Having surgery along with antimicrobial treatment was independently associated with reduced overall mortality. IE by Serratia spp. was more likely to be associated with intravenous drug use, and to present with heart failure and embolic phenomena compared to IE by other non-HACEK Gram-negative bacilli, while mortality was also higher in IE by Serratia spp.

Abstract
BACKGROUND The best management of problematic or infected transvenous permanent pacemaker system is complete surgical or percutaneous intravascular extraction of the pacemaker leads and removal of the generator. We present our experiences in 13 such patients in whom the leads were removed with the less-invasive technique. METHODS From 1996 to 2003, 13 patients, from 31 to 83 years of age (mean, 66.9 +/- 14.0 years), with problematic or infected transvenous permanent pacemaker systems were referred to our department for surgical treatment. In 6 patients, the original pacemakers were dual-chamber. A subxiphoid pericardiotomy was used as the monitoring port during the ventricular lead extraction. In addition, a right parasternal pericardiotomy through the third intercostal space was used as the monitoring port during the atrial lead extraction. RESULTS Pacemaker systems were completely removed in all patients. Three bleeding episodes (23%), including two right atrial tears and one right ventricular rupture, were successfully circumvented through these monitoring ports. Concomitantly, a new epicardial single-chamber device was implanted through the subxiphoid pericardiotomy whenever indicated in 9 patients. All patients recovered and were discharged uneventfully. At a mean follow-up of 24.8 months (range, 1 to 90 months), no recurrent infections were observed. CONCLUSIONS A less-invasive technique for explantation of the complete pacemaker system is feasible. This is a reliable method to eradicate infection. Neither cardiopulmonary bypass nor specific intravascular lead extraction devices, such as locking stylets or laser-assisted sheath, are needed.

Abstract
Despite the use of transvenous methods for extraction of infected leads, failed attempts may result in retained lead fragments. Retained lead fragments may be a focus of continued infection leading to sepsis. We present two patients in which conversion from cardiopulmonary bypass to hypothermic circulatory arrest allowed direct visualization, using venotomies in the superior vena cava and innominate vein to achieve complete removal of retained pacemaker lead fragments. Use of venotomies in the extracardiac venous system is a technical addition to prior descriptions of lead extraction using deep hypothermia and circulatory arrest.

Abstract
Extraction of chronic pacemaker leads has been recommended for infections, prevention of venous thrombosis, migration, and possible perforation. Success with constant traction techniques has been variable, and the cost and morbidity of open chest surgical procedures are prohibitive. Efficacy of a new system for lead extraction using intravascular techniques was analyzed. The system (Cook Pacemaker) uses a locking stylet, which is secured at the distal electrode by counterclockwise rotation to reinforce the lead and facilitate traction, and dilator sheaths that are used to free the lead from adhesions in the venous system. In a series of 56 patients (ages 19-88) who presented for lead extraction because of erosion (5), infection (14), lead replacement (35), or other (2), 86 leads were extracted. Thirty-two were atrial leads and 54 ventricular; 23 had active fixation and 63 passive. Average duration of implant was 58 +/- 42 months (range 1-264). Eighty-four leads were totally removed and two partially removed. For these two leads, the distal tip was not removed; in both cases the locking stylet was not secured at the distal electrode due to obstruction within the lead. Two patients developed arm edema following the procedure, which resolved with elevation. One patient developed a subclavian thrombosis, which resolved with warfarin anticoagulation. Four patients have expired due to unrelated causes. In conclusion, this intravascular approach for extraction of chronic leads is effective, and the procedure is safe when performed by experienced personnel.

Abstract
Infection, though uncommon, can be the most lethal of all potential complications following transvenous pacemaker implantation. Eradication of infection associated with pacemakers requires complete removal of all hardware, including inactive leads. Since 1972, 5,089 patients have had 8,508 pacemaker generators implanted at Montefiore Medical Center. There were 91 infections (1.06%); four of our patients required surgical removal. Nine additional patients were referred for surgical removal of infected transvenous pacemaker leads from other institutions. Surgical methods for removal included use of cardiopulmonary bypass or inflow occlusion. Surgery may be safely used in unstable or elderly patients and should not be reserved as a last resort. This article reviews our surgical experience removing infected pacemaker leads at Montefiore Medical Center.

Abstract
UNLABELLED The long-term results after open intracardiac removal of infected pacing electrodes are presented. METHODS Between 1985 and 1990 open intracardiac removal of 19 infected pacing electrodes was performed in seven patients (six male and one female), with a mean age of 56 years. The indications were: persisting bacteremia in three; generator pocket infection in four; endocarditis in one; and ventricular tachycardia caused by retracted electrodes in one. All electrodes were fixed in the right heart and extraction by closed methods failed. Percutaneous catheter techniques were not applied in these seven patients. In five patients two ventricular electrodes had to be removed, and in two patients a single one. A total of seven atrial electrodes were removed in six patients (one electrode each in five patients; two electrodes in one patient). All atrial and two ventricular electrodes could be removed through a pursestring suture without use of a pump oxygenator. For the removal of ten ventricular electrodes in six patients (two electrodes each in four patients; 1 electrode each in two patients) a right-sided atriotomy was necessary with cardiopulmonary bypass (CPB). Simultaneously, five new pacing systems were implanted. RESULTS There were no early or late mortalities. In January 1991, all seven patients are alive and in a mean New York Heart Association Class 1,3 of heart failure after a mean interval of 33 months. In all cases the infection could controlled with a simultaneous antimicrobial chemotherapy and the postoperative period was free of major complications. CONCLUSION Open intracardiac removal of retained pacing electrodes with or without use of CPB is a safe procedure without major complications. It is mandatory for all infected pacing electrodes that cannot be extracted by closed methods.

Abstract
Within a few months of implantation, permanent pacemaker leads become ensheathed in fibrocollagenous tissue. This tissue may anchor the lead so that it is difficult, dangerous, or impossible to remove it. Leads with bulbous or finned tips are particularly resistant to extraction. The risks of applying traction to an entrapped lead include induction of bradycardia or ventricular tachycardia and fibrillation, invagination of the right ventricle, avulsion of the right ventricular myocardium or tricuspid valve, hemopericardium, and cardiac tamponade. Forceful traction may result in uncoiling of the conductor, disruption of the insulation, or complete fracture, leaving an intravascular remnant that may embolize or be a source for thrombosis. Although fixation and abandonment of an inactive chronically implanted lead is frequently appropriate and is known to pose little long-term risk, the retained inactive lead may interact adversely with a new active lead and then increase the risk of venous thrombosis, serve as a potential nidus for infection, or produce spurious electrical sensing signals that may be sensed by the pulse generator. Absolute indications for lead removal are those in which there would be a life-threatening situation if the lead were to remain in situ. In the absence of an absolute indication, the decision to proceed with extraction must be made by weighing the potential for serious morbidity or mortality against risks of the extraction technique. Techniques for lead removal include traction and open cardiotomy operations. When a portion of the lead is intravascular, forceps, snares, baskets, countertraction, or lead-transection devices may be used to retrieve the fragment.

Abstract
Chronic lead extraction using intravascular countertraction techniques was studied in patients with over 65 different lead models including passive and active fixation devices. Indications for removal of 115 leads implanted 5 days to 264 months (mean 58 months) in 62 patients (mean 65 years) included septicemia, subcutaneous tissue infection, preerosion, free-floating lead, lead trapped in valve, too many leads, pain, and vein thrombosis. The superior vena cava (SVC) approach was attempted in 101 leads and was successful in 82 attempts (71% of total leads). The inferior vena cava (IVC) approach via the femoral vein was required to extract 14 (12%) leads inaccessible to the SVC approach and the 19 leads that failed the SVC approach (29% of total leads). The SVC procedure includes a sized stylet locked at the tip and telescoping sheaths advanced over the lead to the heart. An IVC procedure includes placement of a 16 F sheath workstation via a femoral vein into the right atrium. A deflection catheter and Dotter snare in an 11 F sheath were advanced through the workstation into the right atrium. The lead was maneuvered into position, snared, and pulled into the workstation. For both the SVC and IVC approaches, the leads were removed by applying traction on the lead and countertraction with the sheaths. In experienced hands, these techniques have proven safe and effective for removing chronic transvenous leads.

Abstract
From January, 1970, through December, 1984, nineteen infected or eroded pacemaker units were reimplanted in 17 patients. Characteristics of the patients, types of infecting organisms, surgical management, and complications are described. Optimal treatment of the infected generator pocket requires explantation of the generator unit with utilization of the in situ leads for pacing by an external-demand pacemaker unit. The generator unit is sterilized, and new leads are placed with relocation of the pocket. The old leads are then removed. This technique has been used safely and with excellent results for the past fourteen years.

Abstract
The pathophysiology of late pacemaker pocket infection is poorly understood. We report three cases of late infection caused by Staphylococcus epidermidis. Despite initial local conservative management ultimate removal of the entire pacing system was required. In late pacemaker pocket infection we recommend initial removal of the entire pacing system and replacement on the contralateral side. When retrieval of the lead system requires open-heart surgery epicardial wires should be placed.

Abstract
Of 267 patients having a tined endocardial lead implanted from 1978 to December 1983, three (1.1%) developed pulse generator pocket infection. Proper treatment of this complication involves removal of the pulse generator, continued external pacing via the implanted lead, pocket drainage and administration of specific antibiotics until the infected area clears. In two patients, the electrode could not be removed by traction. A sternotomy was performed, the pericardium was opened, the endocardial electrode was located by palpation, and a purse string suture (PSS) was prepared around it on the right ventricular wall. A new myocardial electrode with its corresponding generator was then implanted to reestablish pacing. Through the PSS the myocardium was incised, the distal end of the endocardial lead was exteriorized and severed, and the PSS was tied. The remaining lead was withdrawn proximally and the surgical wounds were closed. The results of this procedure have been been excellent, allowing the removal of the entrapped leads, with continuous pacing and without the need for extracorporeal circulation.

Abstract
A 71-year-old woman was admitted after partial removal of an infected pacemaker system. Septicemia and subclavian vein thrombosis were present. With combined use of a pigtail catheter and a wire loop originally developed for endoscopic polypectomy, the infected catheter was pulled into the inferior vena cava. Counterclockwise rotation of the pigtail catheter following its fixation to the electrode by the wire loop allowed removal of the tip of the endocardial screw-in electrode from the myocardium and its extraction. Open heart surgery was avoided and the source of chronic infection was removed.

Abstract
Infection remains a significant problem in patients undergoing permanent cardiac pacemaker implantation, and removal of all components is usually required. The transvenous system carries minimal morbidity at implantation, but the development of infection is more life-threatening than in the epicardial system. Although the evolution of the tined porous endocardial lead reduced the incidence of wire displacement, the development of a serious infection is still a problem and may require major surgery for removal. We experienced this problem in a 15-month-old child who developed recurrent sepsis. Attempts at removal of the retained tined porous electrode through the neck incision proved dangerous and unsuccessful. Removal was carried out using cardiopulmonary bypass and infection was promptly controlled.

Abstract
The dislodgment rate of permanent pacing ventricular and atrial endocardial leads has significantly decreased with the incorporation of tines as a fixation device. In contrast, transvenous manual extraction of chronically implanted endocardial leads is, at times, clinically indicated, particularly when pacemaker system infection is present. The success rate of such extraction attempts for ventricular endocardial leads over the past 5 years was reviewed. Extraction was usually successful (six of seven attempts) in patients with silicone rubber nontined (or short-tined) older ventricular endocardial leads (Group A). However, in patients with newer urethane long-tined ventricular endocardial leads (Group B), extraction was unsuccessful in three of four attempts. Because of entrapment of the distal electrode tip in the right ventricular apex, manual traction of these leads resulted in permanent conductor material stretching with resultant urethane insulator material breakage in the region of the joints with proximal and distal electrodes. The one successful extraction in Group B was technically difficult and appeared to create a significant risk of intracardiac lead separation. This experience indicates that with improved pacemaker lead design decreased lead dislodgment has been obtained at the cost of increased difficulty of ventricular endocardial lead extraction. Such difficulty should be anticipated when a clinical decision is made to attempt to extract the new urethane long-tined ventricular leads.

Abstract
To evaluate the effect of antibiotic prophylaxis in pacemaker surgery, 100 patients were randomly assigned to a prophylaxis group receiving cloxacillin or to a control group with no antibiotics. Cloxacillin was given intravenously (2 g) 2 hours before operation, followed by 1 g every 6 hours for 2 days and the same dose perorally for 8 more days postoperatively. Adequate plasma concentrations were obtained in all patients. The follow-up time was 1-43 months. The infection rate was 2% (1/50) in the prophylaxis group and 14% (7/50) in the control group (p less than 0.05). The interval from operation to manifest infection was 9-35 days. In the control group the causal microorganism was Staphylococcus aureus in two patients, Staphylococcus epidermidis in two and unknown in three patients. In the only patient with infection in the prophylaxis group, a methicillin-resistant S. epidermidis was isolated. Infection was initially localized to the pacemaker pocket in seven patients, but septicemia developed in one of them and endocarditis in another. In one patient septicemia appeared initially, without local signs of infection. This study suggests that cloxacillin prophylaxis is of value in routine pacemaker surgery.

Abstract
This is a report of a patient with an impacted, chronically infected transvenous pacemaker lead whose management was complicated by the presence of a functioning contralateral transvenous pacemaker. Treatment included sustained traction on the infected lead, a left subcostal thoracotomy for placement of new sutureless epicardial leads, and retrograde right iliac vein cannulation for final snare removal of the mobilized lead. The patient is currently free of infection, and has normal pacemaker function.

Abstract
Between 1971 and 1978 septicaemia was observed in 14 patients undergoing permanent pacemaker treatment. The causative microorganisms were: S. aureus (9), S. epidermidis (3), alfa-haemolytic streptococci + P. morganii (1), enterococci (1). In 4 patients, a mural endocarditis of the right atrial wall surrounding the electrode was found at operation or autopsy. The interval between the preceding pacemaker operation and onset of septicaemia varied between 2 days and 23 months (median 2 months). In 5 patients, the last operation before septicaemia was performed because of local infection in the pacemaker pocket or along the electrode. A probable portal of entry was found in 11 patients. The electrode was the origin in 8, the pacemaker pocket in one, and a focus outside the pacemaker system in 2. Of the 6 patients treated with antibiotics alone, 3 were cured, 2 died and one is still on treatment. Eight patients underwent various surgical procedures in addition to the antibiotic treatment. In 4 the electrode was completely removed. In 2 of them cardiotomy during extracorporeal circulation had to be used. All of these patients were cured. In 3 the pacemaker system was partially extracted. Only one of them was cured, one developed osteomyelitis and one died. Based on our experience, we now recommend that all foreign material should be removed, if possible, in the presence of septicaemia and/or endocarditis, and that parenteral antibiotic treatment should be given for at least 6 weeks.

Abstract
Clinical and morphologic findings are described in a 62 year old woman with "mixed connective tissue disease" who received corticosteroid therapy, and in whom disseminated and fatal Petriellidium boydii infection with right-sided endocarditis developed. The patient was a gardener. The organism is ubiquitous in soil in many part of the United States; therefore, it is likely that the infection was introduced by this means. Endocarditis due to P. boydii has not been reported previously. In the patient described, massive vegetations nearly obliterated the tricuspid valve orifice, encasing a pacemaker catheter which had been inserted eight years earlier. Although never previously isolated from blood cultures, P. boydii was isolated from 11 consecutive blood cultures. P. boydii is a true fungus and has only recently been appreciated as an opportunistic pathogen in a compromised host.
