Abstract
Cardiac implantable electronic device (CIED) implantation has steadily increased in the United States owing to increased life expectancy, better access to health care, and the adoption of updated guidelines. Transvenous lead extraction (TLE) is an invasive technique for the removal of CIED devices, and the most common indications include device infections, lead failures, and venous occlusion. Although in-hospital and procedure-related deaths for patients undergoing TLE are low, the long-term mortality remains high with 10-year survival reported close to 50% after TLE. This is likely demonstrative of the increased burden of comorbidities with aging. There are guidelines provided by various professional societies, including the Heart Rhythm Society, regarding indications for lead extraction and management of these patients. In this paper, we will review the indications for CIED extraction, procedural considerations, and management of these patients based upon the latest guidelines.

Superior vena cava tear during transvenous lead extraction: Medical management in hemodynamically stable patients. Pacing Clin Electrophysiol 2023. [PMID: 37196145 DOI: 10.1111/pace.14718] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/24/2022] [Revised: 03/31/2023] [Accepted: 05/02/2023] [Indexed: 05/19/2023]
Abstract
INTRODUCTION Superior vena cava (SVC) tear is the most lethal complication during transvenous lead extraction (TLE) with a mortality rate as high as 50%. Treatment involves aggressive attempts to maintain cardiac output and immediate sternotomy to localize and repair the vascular tear. Occlusion balloons have been developed to provisionally occlude the lacerated SVC and to provide hemodynamic stability allowing time for surgery. In case of mediastinal hematoma without hemodynamic instability, the strategy remains unclear. METHODS AND RESULTS We describe two cases of SVC tear during TLE. The first case was a 60-year-old man who presented with a right ventricular single-chamber defibrillator lead fracture and innominate vein stenosis. The RV lead was removed using a laser sheath causing a mediastinal hematoma with no active bleeding during surgical exploration few hours later. The second case was a 28-year-old man that presented with a right atrial (RA) lead fracture and RV lead insulation failure in a dual-chamber defibrillator (ICD). CONCLUSION Both the RA and RV leads were removed with mechanical sheaths, and a mediastinal hematoma was medically managed.

Abstract
Trauma remains a leading cause of death for all age groups, and nearly two-thirds of these individuals suffer thoracic trauma. Due to the various types of injuries, including vascular and nonvascular, interventional radiology plays a major role in the acute and chronic management of the thoracic trauma patient. Interventional radiologists are critical members in the multidisciplinary team focusing on treatment of the patient with thoracic injury. Through case presentations, this article will review the role of interventional radiology in the management of trauma patients suffering thoracic injuries.

Safety and feasibility of trans-venous cardiac device extraction using conscious sedation alone-Implications for the post-COVID-19 era. J Arrhythm 2021; 37:1522-1531. [PMID: 34887957 PMCID: PMC8637087 DOI: 10.1002/joa3.12637] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2021] [Revised: 08/26/2021] [Accepted: 09/13/2021] [Indexed: 11/12/2022] Open
Abstract
BACKGROUND Transvenous lead extraction (TLE) for implantable cardiac-devices is traditionally performed under general anesthesia (GA). This can lead to greater risk of exposure to COVID-19, longer recovery-times and increased procedural-costs. We report the feasibility/safety of TLE using conscious-sedation alone with immediate GA/cardiac-surgery back-up if needed. METHODS Retrospective case-series of consecutive TLEs performed using conscious-sedation alone between March 2016 and December 2019. All were performed in the electrophysiology-laboratory using intravenous Fentanyl, Midazolam/Diazepam with a stepwise approach using locking-stylets/cutting-sheaths, including mechanical-sheaths. Baseline patient-characteristics, procedural-details and TLE outcomes (including procedure-related complications/death) were recorded. RESULTS A total of 130 leads were targeted in 54 patients, mean age ± SD 74.6 ± 11.8years, 47(87%) males; dual-chamber pacemakers (n = 26; 48%), cardiac resynchronization therapy-defibrillators (n = 17; 31%) and defibrillators (n = 8; 15%) were commonest extracted devices. Mean ± SD/median (range) lead-dwell times were 11.0 ± 8.8/8.3 (0.3-37) years, respectively. Extraction indications included systemic infection (n = 23; 43%) and lead/pulse-generator erosion (n = 27; 50%); mean 2.1 ± 2.0 leads were removed per procedure/mean procedure-time was 100 ± 54 min. Local anesthetic (LA) was used for all (mean-dose: 33 ± 8 ml 1% lidocaine), IV drug-doses used (mean ± SD) were: midazolam: 3.95 ± 2.44 mg, diazepam: 4.69 ± 0.89 mg and fentanyl: 57 ± 40 µg. Complete lead-extraction was achieved in 110 (85%) leads, partial lead-extraction (<4 cm-fragment remaining) in 5 (4%) leads. Sedation-related hypotension requiring IV fluids occurred in 2 (managed without adverse-consequences) and hypoxia requiring additional airway-management in none. No procedural deaths occurred, one patient required emergency cardiac surgery for localized ventricular perforation, nine had minor complications (transient hypotension/bradycardia/pericardial effusion not requiring intervention). CONCLUSION TLE undertaken using LA/conscious-sedation was safe/feasible in our series and associated with good clinical outcome/low procedural complications. Reduced risk of aerosolization of COVID-19 and quicker patient recovery/reduced anesthetic risk are potential benefits that warrant further study.

Predictors of perforation during lead extraction: Results of the Canadian Lead ExtrAction Risk (CLEAR) study. Heart Rhythm 2021; 19:1097-1103. [PMID: 34695576 DOI: 10.1016/j.hrthm.2021.10.019] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/17/2021] [Revised: 10/18/2021] [Accepted: 10/19/2021] [Indexed: 01/27/2023]
Abstract
BACKGROUND Transvenous lead extraction can have serious adverse events, such as cardiac or vascular perforation. Risk factors have not been well characterized. OBJECTIVE The purpose of this study was to identify factors associated with perforation and death, and to characterize lead extraction in a large contemporary population. METHODS We performed a retrospective multicenter study examining patients undergoing lead extraction at 8 Canadian institutions from 1996 through 2016. Demographic and clinical data were used to identify variables associated with perforation and mortality using logistic regression modeling. RESULTS A total of 2325 consecutive patients (age 61.9 ±16.5 years) underwent extraction of 4527 leads. Perforation rate was 2.7% (63/2325) and 30-day mortality was 1.6% (38/2325), with mortality of 0.4% due to perforation (10/2325). Variables associated with perforation included no previous cardiac surgery (odds ratio [OR] 3.33; 95% confidence interval [CI] 1.54-7.19; P = .002), female sex (OR 3.27; 95% CI 1.91-5.60; P <.001); left ventricular ejection fraction ≥40% (OR 2.81; 95% CI 1.28-6.14; P = .010); lead age >8 years (OR 2.64; 95% CI 1.52-4.60; P <.001); ≥2 leads extracted (OR 2.49; 95% CI 1.23-5.04; P = .011); and diabetes (OR 2.12; 95% CI 1.16-3.86; P = .014). Variables associated with death included infection as indication for extraction (OR 3.85; 95% CI 1.38-10.73; P = .010); anemia (OR 3.14; 95% CI 1.38-6.61; P = .003), and patient age (OR 1.04; 95% CI 1.01-1.07; P = .012). CONCLUSION Risk factors associated with perforation in lead extraction include no history of cardiac surgery, female sex, preserved left ventricular ejection fraction, lead age >8 years, ≥2 leads extracted, and diabetes.

Abstract
AIMS Several large studies have documented the outcome of transvenous lead extraction (TLE), focusing on laser and mechanical methods. To date there has been no large series addressing the results obtained with rotational lead extraction tools. This retrospective multicentre study was designed to investigate the outcomes of mechanical and rotational techniques. METHODS AND RESULTS Data were collected on a total of 2205 patients (age 66.0 ± 15.7 years) with 3849 leads targeted for extraction in six European lead extraction centres. The commonest indication was infection (46%). The targeted leads included 2879 pacemaker leads (74.8%), 949 implantable cardioverter-defibrillator leads (24.6%), and 21 leads for which details were unknown; 46.6% of leads were passive fixation leads. The median lead dwell time was 74 months [interquartile range (IQR) 41-112]. Clinical success was obtained in 97.0% of procedures, and complete extraction was achieved for 96.5% of leads. Major complications occurred in 22/2205 procedures (1%), with a peri-operative or procedure-related mortality rate of 4/2205 (0.18%). Minor complications occurred in 3.1% of procedures. A total of 1552 leads (in 992 patients) with a median dwell time of 106 months (IQR 66-145) were extracted using the Evolution rotational TLE tool. In this subgroup, complete success was obtained for 95.2% of leads with a procedural mortality rate of 0.4%. CONCLUSION Patient outcomes in the PROMET study compare favourably with other large TLE trials, underlining the capability of rotational TLE tools and techniques to match laser methods in efficacy and surpass them in safety.

Abstract
Trauma is one of the leading causes of death worldwide. Approximately two-thirds of trauma patients have thoracic injuries. Nonvascular injury to the chest is most common; however, while vascular injuries to the chest make up a small minority of injuries in thoracic trauma, these injuries are most likely to require intervention by interventional radiology (IR). IR plays a vital role, with much to offer, in the evaluation and management of patients with both vascular and nonvascular thoracic trauma; in many cases, IR treatments obviate the need for these patients to go to the operating room. This article reviews the role of IR in the treatment of vascular an nonvascular traumatic thoracic injuries.

Endovascular occlusion balloon-related thrombosis during transvenous lead extraction. Europace 2021; 23:1472-1478. [PMID: 33822905 DOI: 10.1093/europace/euab074] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2020] [Accepted: 03/23/2021] [Indexed: 11/14/2022] Open
Abstract
AIMS The aim of this study is to evaluate the incidence, predictors, and outcomes of balloon-related thrombosis (BRT) in patients undergoing transvenous lead extraction (TLE). Use of an endovascular occlusion balloon has improved outcomes of superior vena cava injuries during TLE. Its thrombogenicity in clinical practice is unknown. METHODS AND RESULTS We prospectively evaluated consecutive patients undergoing prophylactic balloon placement during TLE utilizing two procedural workflows: one with the balloon within the inferior vena cava during the entire case (standard cohort) and one limiting the balloon's dwell time (abbreviated cohort). Intracardiac echocardiography was used to evaluate for significant BRT (thrombus > 1 cm) after TLE. Forty-two patients (21 in each group) were included. Age, left ventricular ejection fraction, procedural indication, number of leads, and lead dwell time were similar between the groups. Balloon dwell time was significantly longer in the standard group (128 ± 74 vs. 25 ± 18 min, P < 0.001) as was BRT (14/21 vs. 1/21, P < 0.001). Mean thrombus length and width in the standard group was 3.99 ± 1.40 and 0.45 ± 0.16 cm, respectively and 5.2 × 0.4 cm in one patient in the abbreviated group. Between patients with and without BRT in the standard group, balloon dwell times were similar (113 ± 64 vs. 156 ± 88 min, P = 0.21). One patient in the standard group had a pulmonary embolism on post-operative Day 3 and was initiated on oral anticoagulation. CONCLUSION Prophylactic balloon placement for the entirety of the case is associated with a high incidence of BRT; a finding that is decreased when an abbreviated workflow is utilized.

Abstract
Background Transvenous lead extraction (TLE) plays a critical role in managing patients with cardiovascular implantable electronic devices. Mechanical TLE tools, including rotational sheaths, are used to overcome fibrosis and calcification surrounding leads. Prospective clinical data are limited regarding the safety and effectiveness of use of mechanical TLE devices, especially rotational tools. Objective To prospectively investigate the safety and effectiveness of mechanical TLE in real-world usage. Methods Patients were enrolled at 10 sites in the United States and Europe to evaluate the use of mechanical TLE devices. Clinical success, complete procedural success, and complications were evaluated through follow-up (median, 29 days). Patient data were source verified and complications were adjudicated by an independent clinical events committee (CEC). Results Between October 2018 and January 2020, mechanical TLE tools, including rotational sheaths, were used to extract 460 leads with a median indwell time of 7.4 years from 230 patients (mean age 64.3 ± 14.4 years). Noninfectious indications for TLE were more common than infectious indications (61.5% vs 38.5%, respectively). The extracted leads included 305 pacemaker leads (66.3%) and 155 implantable cardioverter-defibrillator leads (33.7%), including 85 leads with passive fixation (18.5%). A bidirectional rotational sheath was needed for 368 leads (88.0%). Clinical success was obtained in 98.7% of procedures; complete procedural success was achieved for 96.3% of leads. CEC-adjudicated device-related major complications occurred in 6 of 230 (2.6%) procedures. No isolated superior vena cava injury or procedural death occurred. Conclusion This prospective clinical study demonstrates that use of mechanical TLE tools, especially bidirectional rotational sheaths, are effective and safe.

Benefits of routine prophylactic femoral access during transvenous lead extraction. Heart Rhythm 2021; 18:970-976. [PMID: 33577972 DOI: 10.1016/j.hrthm.2021.02.004] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/01/2021] [Revised: 01/26/2021] [Accepted: 02/04/2021] [Indexed: 11/17/2022]
Abstract
BACKGROUND The number of patients requiring lead extraction has been increasing in recent years. Despite significant advances in operator experience and technique, unexpected complications may occur. Prophylactic placement of femoral sheaths allows for immediate endovascular access for emergency procedures and may shorten response time in the event of complications. OBJECTIVE The purpose of this study was to assess the benefits of routine prophylactic femoral access in patients undergoing transvenous lead extraction (TLE) and to evaluate the methods, frequency, and efficacy of the emergency measures used in those patients. METHODS We conducted a retrospective analysis of patients who underwent TLE from January 2012 to February 2019. The data were analyzed with regard to procedural complications and deployment of emergency measures via femoral access. RESULTS Two hundred eighty-five patients (mean age 65.3 ± 15.5 years) were included in the study. Median lead dwell time was 84 months (interquartile range 58-144). Overall complication rate was 4.2% (n = 12), with 1.8% major complications (n = 5). Clinical success rate was 97.2%. Procedure-related mortality was 1.1% (n = 3). Femoral sheaths were actively engaged in 9.1% (n = 26) of cases. Deployment of snares was the most common intervention (n = 10), followed by prophylactic (n = 6) or emergency placement (n = 1) of occlusion balloons, temporary pacing (n = 3), venous angioplasty (n = 3), diagnostic venography (n = 3), and extracorporeal membrane oxygenation (n = 1). We did not observe any femoral vascular complications due to prophylactic sheath placement. CONCLUSION Routine prophylactic placement of femoral sheaths shortens response time and quickly establishes control in the event of various complications that may occur during TLE procedures.

Transvenous lead extraction in a patient with polysplenia and inferior vena cava defect. J Cardiol Cases 2020; 23:41-44. [PMID: 33437340 PMCID: PMC7783646 DOI: 10.1016/j.jccase.2020.09.004] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2020] [Revised: 08/26/2020] [Accepted: 08/30/2020] [Indexed: 11/29/2022] Open
Abstract
A 28-year-old woman with polysplenia was referred to our hospital for atrial lead failure. She had undergone an intracardiac repair (ICR) for incomplete atrioventricular septal defect and the implantation of epicardial pacing leads due to complete atrioventricular block at the age of 1 year. When she was 13 years old, an endocardial dual-chamber pacemaker was implanted via the right subclavian vein because of epicardial lead failure. The contrast-enhanced computed tomography scan revealed an inferior vena cava defect with an azygos vein connection to the superior vena cava, occlusion of the right brachiocephalic vein, a defect of the left brachiocephalic vein, and a persistent left superior vena cava ligated at the ICR. Therefore, lead exchange was indicated. During the operation, the temporary pacing lead and the guidewire for emergent deployment of the Bridge Occlusion Balloon® were advanced through the azygos vein and placed at the right ventricle and the hepatic vein, respectively. Both 11-Fr and 13-Fr mechanical rotational dilator sheaths were needed for the lead extraction owing to dense calcification and tight adhesions. The atrial lead was successfully extracted without any complications despite extremely restricted venous access. A new atrial lead was inserted through the space created by the 13-Fr sheath. <Learning objective: Transvenous lead extraction in patients with polysplenia is technically challenging. These patients often undergo pacemaker implantation in childhood, which results in tight adhesions and dense calcifications on the leads, and venous access is extremely restricted. It may be impossible to use a snare and deploy the endovascular balloon to prevent a catastrophic complication from the right femoral vein to the superior vena cava in cases of the inferior vena cava defect.>

Major cardiac and vascular complications after transvenous lead extraction: acute outcome and predictive factors from the ESC-EHRA ELECTRa (European Lead Extraction ConTRolled) registry. Europace 2020; 21:771-780.

Abstract
AIMS We aimed at describing outcomes and predictors of cardiac avulsion or tear (CA/T) with tamponade and vascular avulsion or tear (VA/T) after transvenous lead extraction (TLE) in the ESC-EHRA European Lead Extraction ConTRolled (ELECTRa) registry. METHODS AND RESULTS A total of 3555 consecutive patients of whom 3510 underwent TLE at 73 centres in 19 European countries were enrolled. Among 58 patients (1.7%) with procedure-related major complications, 49 (84.5%) patients (30 CA/T and 19 VA/T) presented cardiovascular complications requiring pericardiocentesis, chest tube positioning and/or surgical repair. The mortality was 20% in patients with tamponade due to CA/T and 31.6% in patients with VA/T. Pericardiocentesis as first manoeuvre followed by rescue surgical repair was highly effective in case of CA/T (93.8%). At multivariate analysis, CA/T with tamponade was more common in RIATA lead extraction, female patients, leads with a mean dwelling time more than 10 years, and when ≥3 leads were extracted or multiple sheaths required. Occlusion or critical stenosis of superior venous access and the leads mean dwelling time more than 10 years were independent predictors for VA/T, while mechanical dilatation was an independent predictor of a lower incidence of this complication as compared to the use of powered sheaths. CONCLUSIONS In the ELECTRa registry, RIATA lead extraction and superior venous access occlusion/thrombosis are two new independent predictors for cardiac tamponade and major vascular complications, respectively. The use of mechanical sheaths seems to be associated with a lower incidence of VA/T. A strategy of pericardiocentesis followed by a rescue surgical approach seems to be reasonable in order to treat a CA/T with tamponade.

Abstract
BACKGROUND The number of lead extractions is growing because of the greater population and increasing age of individuals with a cardiac implantable electronic device. Lead extraction procedures can be complex undertakings with risk of significant mortality, and vascular tears in the superior vena cava are of greatest concern. OBJECTIVE The purpose of this study was to study whether a novel algorithm that analyzes pre-extraction computed tomographic (CT) images can determine the likelihood and location of lead-lead interactions and lead-vessel attachment within patients' venous vasculatures. This information can be used to identify potential case challenges in the planning stages. METHODS We developed an algorithm to estimate the presence and position of lead-lead interactions and lead-vessel adherences by tracking distance between the leads and distance between the lead and superior vena cava in a sample of 12 patients referred to the United Heart and Vascular Clinic for lead extractions due to infection (n = 5), lead failure (n = 5), and tricuspid regurgitation (n = 2). RESULTS Preliminary results indicate that the developed algorithm successfully identified lead-lead and lead-vascular attachments compared to review of CT images by medical experts. CONCLUSION With future validation and clinical implementation, this algorithm could aid physician preparedness by minimizing intraprocedural emergencies and may improve patient outcomes.

Abstract
BACKGROUND Approximately 105 000 cardiac electronic devices are newly implanted in Germany each year. Germany has the highest implantation rate with respect to population of any European country. Infections in cardiac implants are serious complications, with an associated in-hospital mortality of 5-15%. It is thus very important to optimize the diagnostic and therapeutic strategies by which such infections can be detected early and treated effectively. METHODS This review is based on pertinent publications retrieved by a search in PubMed, with special attention to the current recommendations of international medical specialty societies. RESULTS According to the international literature, the incidence of device-associated infection is 1.7% (in six months) for implanted defibrillators and 9.5% (in two years) for resynchronization devices. No absolute figures on infection rates are available for Germany. Infection can involve either the site where the impulse generator is implanted or the intravascular portion of the electrodes. The most important elements of the diagnostic evaluation are: assessment of the local findings; pathogen identification by culture of peripheral blood, swabs of the infected site, or material recovered at surgery; and transesophageal echocardiography to detect endocarditic deposits on the electrodes or cardiac valves. The treatment consists of appropriate antibiotic administration and the complete removal of all foreign material. These special extractions are generally performed via the transvenous route. With the aid of various sheath systems, the procedure can be carried out safely and effectively, with a success rate above 95% and a complication rate below 3%. The indications for the implantation of a new device after eradication of the infection should be critically reassessed. CONCLUSION Untreated infection carries a high mortality. Evaluation and treatment according to a standardized clinical algorithm facilitate correct and timely diagnosis and the choice of an appropriate therapeutic strategy.

Abstract
Background:
Superior vena cava (SVC) tears are one of the most lethal complications in transvenous lead extraction. An endovascular balloon can occlude the SVC in the event of a laceration, preventing blood loss and offering a more controlled surgical field for repair. An early study demonstrated that proper use of this device is associated with reduced mortality. Thereafter, high-volume extractors at the Eleventh Annual Lead Management Symposium developed a best practice protocol for the endovascular balloon.
Methods:
We collected data on adverse events in lead extraction from July 1, 2016, to July 31, 2018. Data were prospectively collected from both a US Food and Drug Administration–maintained database and physician reports of adverse events as they occurred. We gathered case details directly from extracting physicians. Confirmed SVC tears were analyzed for patient demographics, case details, and index hospitalization mortality.
Results:
From July 1, 2016, to July 31, 2018, 116 confirmed SVC events were identified, of which 44.0% involved proper balloon use and 56.0% involved no use or improper use. When an endovascular balloon was properly used, 45 of 51 patients (88.2%) survived in comparison to 37 of 65 patients (56.9%) when a balloon was not used or improperly used (
P
=0.0002). Furthermore, multivariate regression modeling found that proper balloon deployment was an independent, negative predictor of in-hospital mortality for patients who experienced an SVC laceration (odds ratio, 0.13; 95% CI, 0.04–0.40;
P
<0.001).
Conclusions:
From July 1, 2016, through July 31, 2018, patients undergoing lead extraction were more likely to survive SVC tears when treatment included an endovascular balloon.

Abstract
Abstract
Aims
Transvenous lead extraction for cardiac implantable electronic devices (CIED) is of growing importance. Nevertheless, the optimal anaesthetic approach, general anaesthesia vs. deep sedation (DS), remains unresolved. We describe our tertiary centre experience of the feasibility and safety of DS.
Methods and results
Extraction procedures were performed in the electrophysiology (EP) laboratory by two experienced electrophysiologists. We used intravenous Fentanyl, Midazolam, and Propofol for DS. A stepwise approach with locking stylets, dilator sheaths, and mechanical sheaths via subclavian, femoral, or internal jugular venous access was utilized. Patient characteristics and procedural data were collected. Logistic regression models were used to identify parameters associated with sedation-related complications. Extraction of 476 leads (dwelling time/patient 88 ± 49 months, 30% ICD leads) was performed in 220 patients (64 ± 17 years, 80% male). Deep sedation was initiated with bolus administration of Fentanyl, Midazolam, and Propofol; mean doses 0.34 ± 0.12 μg/kg, 24.3 ± 6.8 μg/kg, and 0.26 ± 0.13 mg/kg, respectively. Deep sedation was maintained with continuous Propofol infusion (initial dose 3.7 ± 1.1 mg/kg/h; subsequently increased to 4.7 ± 1.2 mg/kg/h with 3.9 ± 2.6 adjustments) and boluses of Midazolam and Fentanyl as indicated. Sedation-related episodes of hypotension, requiring vasopressors, and hypoxia, requiring additional airway management, occurred in 25 (11.4%) and 5 (2.3%) patients, respectively. These were managed without adverse consequences. Five patients (2.3%) experienced major intraprocedural complications; there were no procedure-related deaths. All of our logistic regression models indicated intraprocedural support was associated with administration higher Fentanyl doses.
Conclusion
Transvenous lead extraction under DS in the EP laboratory is a safe procedure with high success rates when performed by experienced staff.

Abstract
Abstract
Clinicians accept that there are many unknowns when we make diagnostic and therapeutic decisions. Acceptance of uncertainty is essential for the pursuit of the profession: bedside decisions must often be made on the basis of incomplete evidence. Over the years, physicians sometimes even do not realize anymore which the fundamental gaps in our knowledge are. As clinical scientists, however, we have to halt and consider what we do not know yet, and how we can move forward addressing those unknowns. The European Heart Rhythm Association (EHRA) believes that scanning the field of arrhythmia / cardiac electrophysiology to identify knowledge gaps which are not yet the subject of organized research, should be undertaken on a regular basis. Such a review (White Paper) should concentrate on research which is feasible, realistic, and clinically relevant, and should not deal with futuristic aspirations. It fits with the EHRA mission that these White Papers should be shared on a global basis in order to foster collaborative and needed research which will ultimately lead to better care for our patients. The present EHRA White Paper summarizes knowledge gaps in the management of atrial fibrillation, ventricular tachycardia/sudden death and heart failure.

Abstract
The rise in indications for cardiac implantable electronic devices has necessitated the development of tools for removal of the electrodes that connect the heart to these externally located pacemakers and defibrillators. After implant of a cardiac electrode, variable but progressive fibrous adhesion occurs. Removal of these adhesions can cause devastating complications with high risk of mortality if not treated surgically in a highly expeditious and appropriate manner. This article describes the incidence, risk factors, and diagnosis of these injuries followed by discussion of recent evidence for use of superior vena cava balloon occlusion, and conventional surgical repair of these injuries.

Abstract
The role of the anesthesiologist in lead extraction procedures is multifaceted and highlights the collaborative, multidisciplinary teamwork needed to ensure patient safety and procedural success in these complex cases. Thorough preoperative evaluation and identification of high-risk characteristics enable the anesthesiologist to tailor a comprehensive intraoperative and postoperative care plan for each case. Institutional practices may vary but anesthetic management typically includes general anesthesia with an endotracheal tube, invasive measurement of arterial blood pressure, vascular access for rapid volume expansion, echocardiographic monitoring, preparation for blood transfusion, and initiation of cardiopulmonary bypass in the event of an emergency.

Abstract
The use of cardiac implantable electronic devices (CIEDs) has continued to rise along with indications for their removal. When confronted with challenging clinical scenarios such as device infection, malfunction or vessel occlusion, patients often require the prompt removal of CIED hardware, including associated leads. Recent advancements in percutaneous methods have enabled physicians to face a myriad of complex lead extractions with efficiency and safety. Looking ahead, emerging technologies hold great promise in making extractions safer and more accessible for patients worldwide. This review will provide the most up-to-date indications and procedural approaches for lead extractions and insight on the future trends in this novel field.

Abstract
INTRODUCTION To evaluate the outcomes of video-assisted thoracoscopic surgery (VATS) during transvenous lead extractions (TLEs). METHODS AND RESULTS Ninety-one high-risk patients who underwent TLE in the operating room from January 1, 2015, to March 31, 2017, were included in the study. Of these, 9 patients underwent VATS during TLE. Their clinical characteristics, indications for lead extraction, and complications associated with TLE in the 9 patients who had VATS were compared with those for the 82 patients who did not have VATS. The mean (SD) age of the study patients was 61 (17) years (64.8% were male). The lead dwell time, number of leads extracted, and clinical comorbidities were similar between the 2 groups. Superior vena cava (SVC) tear occurred in 2 of the 9 patients in VATS group and in 1 of the 82 in the non-VATS group (22.2% vs. 1.2%, P = 0.03). Of the 2 patients in the VATS group who had SVC tears, in 1 the tear was visualized immediately and there was no hemodynamic compromise. In the other patient, the SVC tear was within the pericardium; the blood pressure recovered quickly after sternotomy and repair. Both patients had complete lead extraction and survived hospitalization. The patient in the non-VATS group who had an SVC tear had a successful repair but died of postoperative complications. CONCLUSIONS Utilization of VATS to facilitate TLE is beneficial for early recognition of SVC tear and timely surgical repair in select high-risk patients.

Abstract
BACKGROUND Superior vena cava (SVC) injury is a rare but dreaded complication during percutaneous transvenous lead extraction (TLE) that carries high morbidity and mortality. Despite technological advances and improved efficacy, complication rates remain unchanged. OBJECTIVE We sought to develop and test a novel technique that could reduce the risk of SVC injury during TLE. METHODS Fifteen patients referred for TLE of an implantable cardioverter-defibrillator lead were included. Patients underwent fluoroscopic and intracardiac echocardiographic (ICE) imaging of the lead-SVC interface with traction from above, below, and simultaneously. Clinical characteristics, fluoroscopic and ICE findings, and procedural outcomes were collected and analyzed. RESULTS Fourteen of 15 patients were men (93%) with a mean age of 58 years. The mean lead dwell time was 8.09 ± 3.97 years (range 1.08-16.25 years), and 12 of 15 leads (80%) were dual-coil. Acceptable ICE imaging was not possible in 3 of 15 patients (20%). Simultaneous traction showed greater leftward fluoroscopic shift compared with traction from above (24.96 ± 8.82 mm vs 13.68 ± 6.86 mm; P < .01), created greater separation between the lead and the SVC wall upon ICE imaging (2.0 ± 0.52 mm vs 1.24 ± 0.38 mm; P < .01), and maintained a more parallel relationship of the lead with the SVC wall (24.41° ± 4.14° vs 27.91° ± 4.92°; P < .05). CONCLUSION In patients presenting for TLE, simultaneous traction results in increased separation and a more parallel alignment of the lead and SVC wall, allowing the sheath to be better oriented in the desired cleavage plane. This improved sheath alignment is particularly critical when powered sheaths are to be used.

Abstract
With increasing use of cardiovascular implantable electronic devices, the need for lead extractions has increased to an annual volume of more than 10,000 extractions worldwide. This article provides a focused clinical commentary on the perioperative management, identification, and treatment of life-threatening complications associated with lead extractions. In addition, a summary of indications, techniques, and lead extraction complications is provided. Although uncommon, lead extractions are associated with a consistent rate of major procedure-related complications and mortality. Major life-threatening complications include vascular laceration, cardiac avulsion, hemothorax, pericardial effusion, and cardiac arrest. Comprehensive preoperative risk assessment and adequate planning and preparedness are crucial to decreasing all procedure-related adverse events. The location of the procedure (electrophysiology suite v hybrid operating room) and the nature of cardiac surgical backup are determined after meticulous risk stratification. In addition to decisions on vascular access, invasive monitoring, and modality of rhythm support, transesophageal echocardiography plays a crucial role in early diagnosis, timely management, and potential prevention of these complications.

Abstract
Due to new indications and improved technology, the incidence of laser lead extraction (LLE) has significantly increased over the past years. While LLE has been well studied and proven to be safe and effective, only few studies are geared toward the anesthesiologist's role during high-risk LLEs. This article utilized both a focused review and authors' experience to investigate anesthetic protocols during LLEs. Through this review, we recommend best practices for the anesthesiologist including appropriate procedure location, onsite availability of a cardiac surgeon, availability of a cardiopulmonary bypass machine, and intraoperative use of echocardiography to detect and address potential complications during high-risk LLEs.

Abstract
BACKGROUND Many clinicians use the strategy of prophylactically placing an endovascular balloon before transvenous lead extraction, yet there are no data regarding this practice. OBJECTIVE This study assesses long-term outcomes of prophylactic placement of an endovascular balloon in the venae cavae of patients during transvenous lead extraction. METHODS From April 1, 2016 to March 31, 2017 data were prospectively collected at 2 international cardiovascular centers on patients who had the balloon prophylactically placed in the venae cavae. Patients were monitored for a minimum of 3 months to capture any associated adverse events. RESULTS Twenty-one patients had the balloon prophylactically placed in the venae cavae during lead extraction. Sixteen patients were male (76%); the mean age was 57.6 ± 18.7 years; and the mean body mass index was 26.1 ± 4.4 kg/m2. The mean lead dwell time was 11.2 ± 8.3 years, with an average of 2.2 ± 1.1 leads per case, and most indications for extraction were noninfectious (62%). Two minor complications (10%, pocket hematomas) and 1 major complication (5%, cardiac tamponade) occurred during the procedure. All cases (100%) were procedural successes, and all patients (100%) were discharged alive. On follow-up (6.8 ± 3.7 months), all patients were alive and reported no adverse events related to prophylactic balloon placement, such as pulmonary emboli or deep venous thrombi. CONCLUSION During the study period, we observed no acute or long-term adverse outcomes associated with prophylactic placement of an endovascular balloon in the venae cavae of patients undergoing transvenous lead extraction.
