Comparison between catheter ablation versus permanent pacemaker implantation as an initial treatment for tachycardia-bradycardia syndrome patients: a prospective, randomized trial.

BACKGROUND: Clinical outcomes after catheter ablation (CA) or pacemaker (PM) implantation for the tachycardia-bradycardia syndrome (TBS) has not been evaluated adequately. We tried to compare the efficacy and safety outcomes of CA and PM implantation as an initial treatment option for TBS in paroxysmal atrial fibrillation (AF) patients. METHODS: Sixty-eight patients with paroxysmal AF and TBS (mean 63.7 years, 63.2% male) were randomized, and received CA (n = 35) or PM (n = 33) as initial treatments. The primary outcomes were unexpected emergency room visits or hospitalizations attributed to cardiovascular causes. RESULTS: In the intention-to-treatment analysis, the rates of primary outcomes were not significantly different between the two groups at the 2-year follow-up (19.8% vs. 25.9%; hazard ratio (HR) 0.73, 95% confidence interval (CI) 0.25-2.20, P = 0.584), irrespective of whether the results were adjusted for age (HR 1.12, 95% CI 0.34-3.64, P = 0.852). The 2-year rate of recurrent AF was significantly lower in the CA group compared to the PM group (33.9% vs. 56.8%, P = 0.038). Four patients (11.4%) in the CA group finally received PMs after CA owing to recurrent syncope episodes. The rate of major or minor procedure related complications was not significantly different between the two groups. CONCLUSION: CA had a similar efficacy and safety profile with that of PM and a higher sinus rhythm maintenance rate. CA could be considered as a preferable initial treatment option over PM implantation in patients with paroxysmal AF and TBS. TRIAL REGISTRATION: KCT0000155.

Fatores Associados aos Custos do Tratamento no Primeiro Ano após Implantes Iniciais ou Trocas de Geradores de Pulsos de Marca-passos Cardíacos / Factors Associated with the Treatment Costs within the First Year after Pacemaker Implantation or Pulse Generator Replacement

Resumo Fundamento O uso de marca-passos cardíacos artificiais tem crescido constantemente, acompanhando o envelhecimento populacional. Objetivos Determinar as taxas de readmissões hospitalares e complicações após implante de marca-passo ou troca de gerador de pulsos e avaliar o impacto desses eventos nos custos anuais do tratamento sob a perspectiva do Sistema Único de Saúde (SUS). Métodos Registro prospectivo, com dados derivados da prática clínica assistencial, coletados na hospitalização índice e durante os primeiros 12 meses após o procedimento cirúrgico. O custo da hospitalização índice, do procedimento e do seguimento clínico foram estimados de acordo com os valores reembolsados pelo SUS e analisados ao nível do paciente. Modelos lineares generalizados foram utilizados para estudar fatores associados ao custo total anual do tratamento, adotando-se um nível de significância de 5%. Resultados No total, 1.223 pacientes consecutivos foram submetidos a implante inicial (n= 634) ou troca do gerador de pulsos (n= 589). Foram observados 70 episódios de complicação em 63 pacientes (5,1%). A incidência de readmissões hospitalares em um ano foi de 16,4% (IC 95% 13,7% - 19,6%) após implantes iniciais e 10,6% (IC 95% 8,3% - 13,4%) após trocas de geradores. Doença renal crônica, histórico de acidente vascular encefálico, tempo de permanência hospitalar, necessidade de cuidados intensivos pós-operatórios, complicações e readmissões hospitalares mostraram um impacto significativo sobre o custo anual total do tratamento. Conclusões Os resultados confirmam a influência da idade, comorbidades, complicações pós-operatórias e readmissões hospitalares como fatores associados ao incremento do custo total anual do tratamento de pacientes com marca-passo.

Abstract Background The use of artificial cardiac pacemakers has grown steadily in line with the aging population. Objectives To determine the rates of hospital readmissions and complications after pacemaker implantation or pulse generator replacement and to assess the impact of these events on annual treatment costs from the perspective of the Unified Health System (SUS). Methods A prospective registry, with data derived from clinical practice, collected during index hospitalization and during the first 12 months after the surgical procedure. The cost of index hospitalization, the procedure, and clinical follow-up were estimated according to the values reimbursed by SUS and analyzed at the patient level. Generalized linear models were used to study factors associated with the total annual treatment cost, adopting a significance level of 5%. Results A total of 1,223 consecutive patients underwent initial implantation (n=634) or pulse generator replacement (n=589). Seventy episodes of complication were observed in 63 patients (5.1%). The incidence of hospital readmissions within one year was 16.4% (95% CI 13.7% - 19.6%) after initial implants and 10.6% (95% CI 8.3% - 13.4%) after generator replacements. Chronic kidney disease, history of stroke, length of hospital stays, need for postoperative intensive care, complications, and hospital readmissions showed a significant impact on the total annual treatment cost. Conclusions The results confirm the influence of age, comorbidities, postoperative complications, and hospital readmissions as factors associated with increased total annual treatment cost for patients with pacemakers.

Comparison of Perioperative and Postoperative Outcomes Among 3 Left Atrial Incisions: Conventional Direct, Transseptal, and Superior Septal Left Atriotomy.

BACKGROUND: Achieving optimal exposure of the mitral valve during surgical intervention poses a significant challenge. This study aimed to compare perioperative and postoperative outcomes associated with 3 left atriotomy techniques in mitral valve surgery-the conventional direct, transseptal, and superior septal approaches-and assess differences during the surgical procedure and the postoperative period. METHODS: Inclusion criteria were patients undergoing mitral valve surgery from January 2010 to December 2020, categorized into 3 cohorts: group 1 (conventional direct; n = 115), group 2 (transseptal; n = 33), and group 3 (superior septal; n = 59). To bolster sample size, the study included patients undergoing mitral valve surgery independently or in conjunction with other procedures (eg, coronary artery bypass grafting, aortictricuspid surgery, or maze procedure). RESULTS: No substantial variance was observed in the etiology of mitral valve disease across groups, except for a higher incidence of endocarditis in group 3 (P = .01). Group 1 exhibited a higher frequency of elective surgeries and isolated mitral valve procedures (P = .008), along with reduced aortic clamping and cardiopulmonary bypass durations (P = .002). Conversely, group 3 patients represented a greater proportion of emergency procedures (P = .01) and prolonged intensive care unit and hospital stays (P = .001). No significant disparities were detected in terms of permanent pacemaker implantation, postoperative complications, or mortality among the groups. CONCLUSION: Mitral valve operations that employed these 3 atriotomy techniques demonstrated a safe profile. The conventional direct approach notably reduced aortic clamping and cardiopulmonary bypass durations. The superior septal method was primarily employed for acute pathologies, with no significant escalation in postoperative arrhythmias or permanent pacemaker implantation, although these patients had prolonged intensive care unit and hospital stays. These outcomes may be linked to the underlying pathology and nature of the surgical intervention rather than the incision method itself.

Perioperative management of patients with cardiac implantable electronic devices.

The use of cardiac implantable electronic devices (CIEDs) has increased significantly in recent years. Consequently, more patients with CIEDs will undergo surgery during their lifetime, and thus the involvement of anesthesiologists in the perioperative management of CIEDs is increasing. With ongoing advancements in technology, many types of CIEDs have been developed, including permanent pacemakers, leadless pacemakers, implantable cardioverter defibrillators, cardiac resynchronization therapy-pacemakers/defibrillators, and implantable loop recorders. The functioning of CIEDs exposed to an electromagnetic field can be affected by electromagnetic interference, potential sources of which can be found in the operating room. Thus, to prevent potential adverse events caused by electromagnetic interference in the operating room, anesthesiologists must have knowledge of CIEDs and be able to identify each type. This review focuses on the perioperative management of patients with CIEDs, including indications for CIED implantation to determine the baseline cardiovascular status of patients; concerns associated with CIEDs before and during surgery; perioperative management of CIEDs, including magnet application and device reprogramming; and additional perioperative provisions for patients with CIEDs. As issues such as variations in programming capabilities and responses to magnet application according to device can be challenging, this review provides essential information for the safe perioperative management of patients with CIEDs.

Malignant Neoplasms Arising in the Cardiac Pacemaker Cavity: A Systematic Review.

Cancer is the abnormal proliferation of physiologically inadequate cells. Studies have identified the cardiac pacemaker pocket as a site of rare neoplasms. To evaluate the clinical outcomes, treatment, prognosis, and individualized management of tumors originating in the cardiac pacemaker pocket, a systematic review was conducted using case reports and case series available in the PubMed/Medline, Science Direct, Cochrane Central, LILACS, and Scientific Electronic Library Online (Scielo) databases. Pacemaker pocket tumors affected patients with a mean age of 72.9 years, with a higher incidence in males (76.9%, n = 10). The average time for neoplasm development was 4.4 years (54.07 months). The most prevalent model was Medtronic (38.4%, n = 5), with titanium (83.3%) being the most common metal composition. Chemotherapy was the most performed procedure among patients (38.4%), followed by radiation therapy (38.4%) and surgical tumor resection (30.7%). Six analyzed cases (46.1%) resulted in death, and four patients (30.7%) achieved a cure. Patients with pacemakers should be routinely evaluated for the occurrence of malignant tumors at the site of device implantation.

Monocyte/High-Density Lipoprotein Ratio Is Associated with Atrial High-Rate Episodes within One Year Detected by Cardiac Implantable Electronic Devices.

OBJECTIVE: To investigate the risk factors for predicting atrial high-rate episodes (AHREs) detected by cardiac implantable electronic devices (CIEDs). METHODS: A total of 140 patients with CIED in our hospital from June 2013 to June 2018 were included and were followed up to observe whether they had AHREs. AHRE are defined as atrial rate ≥ 175 times/minute, lasting > 5 minutes, and reviewed by an experienced electrophysiologist with unclear clinical diagnosis. The patients fasted for 12 hours after implantation, and blood samples were collected for biochemical, lipid, and whole blood count detection. Follow-up was regular after discharge to record follow-up data of each patient and conduct statistical analysis. RESULTS: One hundred and forty patients were implanted with dual-chamber pacemakers, their median age was 70 years old, 44.29% were male, 27 patients had AHRE within one year, and AHRE incidence rate was 19.29%. The microcytic to hypochromic (M/H) ratio was calculated for all AHRE patients and compared with the patients without AHRE; the M/H value of AHRE patients was significantly higher. Throughout the entire follow-up period, a total of 44 patients developed AHRE; when adjusted by multivariate analysis, only M/H ratio ≥ 4.5 vs. < 4.5 had statistical significance, and the adjusted hazard ratio value was 4.313 (1.675-11.105). CONCLUSION: As an indicator, M/H ratio may play an important role in the occurrence and development of atrial fibrillation and can be used as a predictor of AHRE in patients with CIED.

Riesgo arrítmico en episodios únicos o recurrentes de síncope inexplicado con bloqueo completo de rama / Arrhythmic risk in single or recurrent episodes of unexplained syncope with complete bundle branch block

Introducción y objetivos: Los pacientes con un episodio sincopal inexplicable único (ESU) y bloqueo completo de rama del haz de His (BcR) con frecuencia se tratan de manera más conservadora que aquellos con episodios recurrentes (ESR). El objetivo fue analizar si existen diferencias entre pacientes con ESU o ESR y BcR en cuanto al riesgo arrítmico, el rendimiento diagnóstico de las pruebas y los resultados clínicos. Métodos: Estudio de cohorte de pacientes consecutivos con seguimiento medio de 3 años. Fueron estudiados mediante un protocolo escalonado basado en un estudio electrofisiológico y seguimiento con un monitor cardiaco implantable (MCI). Resultados: De los 503 pacientes incluidos en el estudio, 238 (47,3%) referían un ESU. El riesgo de síncope arrítmico fue similar en ambos grupos (58,8% ESU frente a 57,0% ESR; p=0,68), también tras ajustar por variables de confusión (HR=1,06; IC95%, 0,81-1,38; p=0,674). No se encontraron diferencias significativas en cuanto a los resultados del estudio electrofisiológico y la rentabilidad diagnóstica del monitor cardiaco implantable. Un total de 141 (59,2%) pacientes con ESU y 154 (58,1%) con ESR requirieron el implante de un dispositivo cardiaco (p=0,797). Tras el tratamiento adecuado, 35 (7%) pacientes presentaron recurrencia del síncope. La tasa de recurrencia y la mortalidad también fueron similares. Conclusiones: Los pacientes con BcR y síncope tienen un alto riesgo de tener una etiología arrítmica, aunque solo hayan presentado un episodio aislado. Los pacientes con ESU y ESR tienen un riesgo arrítmico similar y presentan un pronóstico similar, por lo que no existe una justificación clínica para no tratarlos de la misma manera.(AU)

Introduction and objectives: Patients with a single syncopal episode (SSE) and complete bundle branch block (cBBB) are frequently managed more conservatively than patients with recurrent episodes (RSE). The objective of this study was to analyze if there are differences between patients with single or recurrent unexplained syncope and cBBB in arrhythmic risk, the diagnostic yield of tests, and clinical outcomes. Methods: Cohort study of consecutive patients with unexplained syncope and cBBB with a median follow-up time of 3 years. The patients were evaluated via a stepwise workup protocol based on electrophysiological study (EPS) and long-term follow-up with an implantable cardiac monitor. Results: Of the 503 patients included in the study, 238 (47.3%) had had only 1 syncopal episode. The risk of an arrhythmic syncope was similar in both groups (58.8% in SSE vs 57.0% in RSE; P=.68), also after adjustment for possible confounding variables (HR, 1.06; 95%CI, 0.81-1.38; P=.674). No significant differences between the groups were found in the EPS results and implantable cardiac monitor diagnostic yield. A total of 141 (59.2%) patients with SSE and 154 (58.1%) patients with RSE required cardiac device implantation (P=.797). After appropriate treatment, 35 (7%) patients had recurrence of syncope. The recurrence rate and mortality were also similar in both groups. Conclusions: Patients with cBBB and unexplained syncope are at high risk of an arrhythmic etiology, even after the first syncopal episode. Patients with SSE and RSE have a similar arrhythmic risk and similar outcomes, and therefore there is no clinical justification for not managing them in the same manner.(AU)

Unusual presentation of asymptomatic subacute lead-related ventricular perforation beyond the pericardium without pericardial effusion: a case report.

The clinical manifestations of subacute pacemaker lead-related cardiac perforations are highly variable. Patients with subacute perforations can present with a variety of symptoms, whereas those with acute perforations usually present with cardiac tamponade that necessitates emergent pericardiocentesis. A 32-year-old woman underwent pacemaker implantation for sick sinus syndrome. An active-fixation atrial lead was fixed to the right atrial appendage, and a ventricular lead was fixed to the right ventricle (RV) apex, with acceptable parameters. Two weeks postoperative, the patient visited the clinic for routine examination of the pacemaker parameters. Chest X-ray showed migration of the RV lead beyond the cardiac silhouette. Echocardiography revealed no evidence of pericardial effusion or tamponade. Computed tomography revealed that the RV lead was positioned beyond the RV and pericardium and into the anterior chest wall. Procedural lead revision was performed with cardiothoracic surgery backup. The lead was retracted after loosening the active-fixation screw and inserting the stylet. The lead was placed in the RV septum with active fixation. The procedure was completed without complications, and the patient was discharged after 3 days. Subacute lead perforations can present with various symptoms, and some patients may be asymptomatic without pericardial effusion. Altered lead parameters frequently provide the first indication for the diagnosis of cardiac perforation. Transvenous lead revision with surgical backup is an alternative to surgical extraction.

Concomitant Coronary Artery Disease and Persistent Left Superior Vena Cava in a Patient Presenting With Symptomatic Sinus Bradycardia: A Case Report.

Persistent left superior vena cava (PLSVC) is a congenital venous anomaly. It is frequently associated with other cardiac anomalies. The presence of dual superior vena cava is due to the lack of development of the left cardinal vein in utero. The coronary sinus gets dilated as a result of increased blood flow to the right heart and may be seen on echocardiography. This case describes a 50-year-old lady who presented to the emergency department with lightheadedness, nausea, and vomiting for one day, and her electrocardiogram showed a heart rate of 30 beats per minute. A temporary pacemaker was placed. She had a history of asymptomatic PLSVC diagnosed six months ago through percutaneous coronary intervention. A permanent pacemaker was passed through PLSVC to access the right ventricle and she was discharged home after five days of an uneventful hospital course. Clinicians should be aware of this rare congenital anomaly and its potential complications, particularly in patients with unexplained syncope or bradycardia. Further research is needed to better comprehend the clinical presentation, diagnostic evaluation, and management of PLSVC-related cardiac abnormalities.

[The ECG in cardiac rehabilitation]. / Das EKG in der Rehabilitation.

The concept and the benefits of cardiac rehabilitation are well established and scientifically proven. In the context of shortened in-hospital stays and older patients receiving more complex interventions, complications of those procedures might occur during cardiac rehabilitation. This article discusses guideline-directed diagnosis and treatment of complications after transcatheter aortic valve replacement, especially delayed-onset heart block, post-operative atrial fibrillation, and acute coronary ischemia in the setting of pre-existent bundle branch block.

Pectoral nerve blocks for transvenous subpectoral pacemaker insertion in children: a randomized controlled study.

BACKGROUND: Postoperative pain management after pacemaker insertion routinely requires opioid agents, nonsteroidal anti-inflammatory drugs, or paracetamol. However, interest in opioid-sparing multimodal pain management to minimize postoperative narcotic use has increased recently. This study aimed to assess the pectoral nerve (PECS) block versus standard treatment on postoperative pain control and opioid consumption in pediatric patients after transvenous subpectoral pacemaker insertion. METHODS: In this randomized controlled study, 40 pediatric patients underwent transvenous subpectoral pacemaker insertion with either congenital or postoperative complete heart block. Patients were randomly assigned to two groups: Group C (control) received conventional analgesic care without any block and Group P (pectoral) received a PECS block. Demographics, procedural variables, postoperative pain, and postoperative opioid consumption were compared between the two groups. RESULTS: In children undergoing transvenous subpectoral pacemaker insertion, the PECS block was associated with a longer procedure time; however, the cumulative dose of fentanyl and atracurium was reduced and the hemodynamic profile was superior in Group P compared with Group C intraoperatively. Postoperatively, the PECS block was associated with lower postprocedural pain scores, which was reflected by the longer interval before the first call for rescue analgesia and lower postoperative morphine consumption, without an increase in the rate of complications. CONCLUSION: Ultrasound-guided PECS blocks are associated with a good intraoperative hemodynamic profile, reduced postoperative pain scores, and lower total opioid consumption in children undergoing transvenous subpectoral pacemaker placement.

Arrhythmic risk in single or recurrent episodes of unexplained syncope with complete bundle branch block.

INTRODUCTION AND OBJECTIVES: Patients with a single syncopal episode (SSE) and complete bundle branch block (cBBB) are frequently managed more conservatively than patients with recurrent episodes (RSE). The objective of this study was to analyze if there are differences between patients with single or recurrent unexplained syncope and cBBB in arrhythmic risk, the diagnostic yield of tests, and clinical outcomes. METHODS: Cohort study of consecutive patients with unexplained syncope and cBBB with a median follow-up time of 3 years. The patients were evaluated via a stepwise workup protocol based on electrophysiological study (EPS) and long-term follow-up with an implantable cardiac monitor. RESULTS: Of the 503 patients included in the study, 238 (47.3%) had had only 1 syncopal episode. The risk of an arrhythmic syncope was similar in both groups (58.8% in SSE vs 57.0% in RSE; P=.68), also after adjustment for possible confounding variables (HR, 1.06; 95%CI, 0.81-1.38; P=.674). No significant differences between the groups were found in the EPS results and implantable cardiac monitor diagnostic yield. A total of 141 (59.2%) patients with SSE and 154 (58.1%) patients with RSE required cardiac device implantation (P=.797). After appropriate treatment, 35 (7%) patients had recurrence of syncope. The recurrence rate and mortality were also similar in both groups. CONCLUSIONS: Patients with cBBB and unexplained syncope are at high risk of an arrhythmic etiology, even after the first syncopal episode. Patients with SSE and RSE have a similar arrhythmic risk and similar outcomes, and therefore there is no clinical justification for not managing them in the same manner.

Propofol and Kearns-Sayre Syndrome: An idiographic approach.

With the focus on an idiographic approach whereby the observations incorporated the various dimensions of individual functioning 'top-down' to 'bottom-up', this case report describes the successful management of a 14-year-old girl with Kearns-Sayre syndrome and Dyggve-Melchior-Clausen disease requiring a transvenous permanent pacemaker implantation for complete heart block. The patient presented to a tertiary care centre in Muscat, Oman, in 2023 seeking consultation. The current idiographic approach appears to have a heuristic value for 2 interrelated reasons. Firstly, it is unlikely that even tertiary care units can accrue such rare presentations and scrutinise them under nomothetic approach. Secondly, by employing the idiographic approach that is capable of examining each case in-depth, the aspiration for good health and well-being may come to the forefront. To the best of the authors' knowledge this is the first published idiographic report in anaesthesia care.

Troubleshooting During Temporary Epicardial Lead Implantation in a Child with an Erosive Twiddler's Syndrome and Multiple Sternotomies: A case report.

Temporary epicardial cardiac pacing in patients with bradyarrhythmias may be used as a bridge to implantation of a permanent pacemaker. The temporary epicardial lead placement may sometimes necessitate a sternotomy that may pose a challenge in patients who have had multiple earlier sternotomies. The difficulty in accessing the epicardium for urgent implantation of temporary epicardial pacing leads depends on the extent of adhesions in such patients. We report an 8-year-8-month-old girl with a pacemaker with an extruded pulse generator and difficult myocardial access due to 5 prior transsternal procedures. The child presented to a tertiary care hospital in Muscat, Oman, in 2021. A trouble-shooting technique was adopted to achieve temporary epicardial pacing to provide time for a course of antibiotic therapy administration. A permanent transvenous pulse generator system was implanted after 7 days of temporary pacing.
