    Quality of life and physical capacity after long-term right ventricular pacing in young adults with congenital atrioventricular block
    (2012) SILVA, K. R.; COSTA, R.; OLIVEIRA JR., R. M.; MARTINELLI FILHO, M.; LACERDA, M. S.; HUANG, A.; ROSSI, M. B.; MATHIAS JR., W.; PIETROBON, R.; STOLF, N. A. G.
    Background: Although several studies have demonstrated the deleterious consequences of chronic right ventricular (RV) pacing on ventricular function and synchronicity, its effects on health-related quality of life (HRQL) and physical capacity remains uncertain. Objectives: To evaluate the effect of RV pacing on HRQL and physical capacity of children and young adults with congenital complete atrioventricular (AV) block. Methods: Fifty consecutive patients with permanent RV cardiac pacing due to congenital AV block and under clinical follow-up for more than one year were enrolled. Multidimensional HRQL was assessed with the Short Form-36 Health Survey (SF-36) and Child Health Questionnaire (CHQ-PF50). Physical capacity was tested by the 6-minute walk distance test (6MWD). The scores for each domain and the distance performed at the 6MWD test were compared with demographic and clinical characteristics of patients, using the Student’s t-test and Qui-squaretest. Results: Domains presenting lower scores were Vitality (63.0±20.6), Pain(66.5±25.1) and Mental Health (67.3±20.4) in the SF-36 questionnaire; General Health Perceptions (64.0±15.0) and Parental Impact-Emotional (69.0±30.0) in the CHQ-PF50. Female gender (P=0.026), DDD pacing mode (0.008) and normal left ventricular ejection fraction (0.002) were associated with higher quality of life scores. The average distance performed at the 6MWD test was 677,2 meters (454,5 to 852,8). The 6MWD showed significant association with age (P=0.004), normal ventricular function (P= 0.031) and the absence of cardiovascular drugs use (P= 0.018). Conclusions: The results of this analysis indicated that chronic RV pacing did not affect the HRQL and physical capacity of young patients. Female gender, DDD pacing, normal ventricular function and the absence of cardiovascular medications were associated with better HRQL scores and with better results at 6MWD test.

    Pacemakers, implantable cardiac defibrillators, and cardiac resynchronization therapy devices are potentially lifesaving treatments for a number of cardiac conditions but are not without risk. Most concerning is the risk of a cardiac implantable electronic device (CIED) infection, which is associated with significant morbidity, increased hospitalizations, reduced survival, and increased health care costs. Recommended preventive strategies such as administration of intravenous antibiotics before implantation are well-recognized. Uncertainties have remained about the role of various preventive, diagnostic, and treatment measures such as skin antiseptics, pocket antibiotic solutions, antibacterial envelopes, prolonged antibiotics post-implantation, and others. When compared with previous guidelines or consensus statements, the present consensus document gives guidance on the use of novel device alternatives, novel oral anticoagulants, antibacterial envelopes, prolonged antibiotics post-implantation, as well as definitions on minimum quality requirements for centres and operators and volumes. The recognition that an international consensus document focused on management of CIED infections is lacking, the dissemination of results from new important randomized trials focusing on prevention of CIED infections, and observed divergences in managing device-related infections as found in an European Heart Rhythm Association worldwide survey, provided a strong incentive for a Novel 2019 International State-of-the-art Consensus document on risk assessment, prevention, diagnosis, and treatment of CIED infections.

    Effectiveness and Safety of Transvenous Removal of Cardiac Pacing and Implantable Cardioverter-defibrillator Leads in the Real Clinical Scenario
    (2020) COSTA, Roberto; SILVA, Katia Regina da; CREVELARI, Elizabeth Sartori; NASCIMENTO, Wagner Tadeu Jurevicius; NAGUMO, Marcia Mitie; MARTINELLI FILHO, Martino; JATENE, Fabio Biscegli
    Background: Transvenous lead extraction (TLE) of cardiac implantable electronic devices (CIED) is an uncommon procedure and requires specialized personnel and adequate facilities. Objectives: To evaluate the effectiveness and safety of the removal of CIED leads and to determine risk factors for surgical complications and mortality in 30 days. Methods: Prospective study with data derived from clinical practice. From January 2014 to April 2020, we included 365 consecutive patients who underwent TLE, regardless of the indication and surgical technique used. The primary outcomes were: success rate of the procedure, combined rate of major complications and intraoperative death. Secondary outcomes were: risk factors for major intraoperative complications and death within 30 days. Univariate and multivariate analysis were used, with a significance level of 5%. Results: Procedure success rate was 96.7%, with 90.1% of complete success and 6.6% of clinical success. Major intraoperative complications occurred in 15 (4.1%) patients. Predictors of major complications were: lead dwelling time >= 7 years (OR = 3.78, p = 0.046) and change in surgical strategy (OR = 5.30, p = 0.023). Functional class III-IV (OR = 6.98, p <0.001), renal failure (OR = 5.75, p = 0.001), CIED infection (OR = 13.30, p <0.001), number of procedures performed (OR = 77.32, p <0.001) and major intraoperative complications (OR = 38.84, p <0.001) were predictors of 30-day mortality. Conclusions: The results of this study, which is the largest prospective registry of consecutive TLE procedures in Latin America, confirm the safety and effectiveness of this procedure in the context of real clinical practice.

    Effectiveness of epicardial atrial pacing using a bipolar steroid-eluting endocardial lead with active fixation in an experimental model
    (2013) BUENO, Savia Christina Pereira; TAMAKI, Wagner Tetsuji; SILVA, Marcelo Fiorelli Alexandrino da; ZAMBOLIM, Cristiane Maciel; SILVA, Katia Regina da; MARTINELLI FILHO, Martino; COSTA, Roberto
    PURPOSE: To assess the effectiveness of bipolar epicardial atrial pacing using an active fixation bipolar endocardial lead implanted on the atrial surface in an experimental model. METHODS: A total of ten Large White adult pigs underwent pacemaker implantation under general anesthesia. Atrial pacing and sensing parameters were obtained at the procedure, immediate postoperative period and on the 7th and the 30th postoperative in unipolar and bipolar configurations. RESULTS: All procedures were successfully performed. There were no perioperative complications and no early deaths. Atrial pacing and sensing parameters for both unipolar and bipolar modes remained stable throughout the study. We observed a progressive increase in atrial thresholds, ranging from 0.49 +/- 0.35 (at implantation) to 1.86 +/- 1.31 volts (30th postoperative day), in unipolar mode. Atrial impedance measurements decreased slightly over time, ranging from 486.80 +/- 126.35 Ohms (at implantation) to 385.0 +/- 80.52 Ohms (30th postoperative day). Atrial sensing measures remained stable from the immediate postoperative period until the end of the study. CONCLUSION: The bipolar active fixation endocardial lead implanted epicardially can provide stable conditions of pacing and sensing parameters throughout the postoperative follow-up.

    Long-Term Follow-Up of Implantable Cardioverter-Defibrillator for Secondary Prevention in Chagas' Heart Disease
    (2012) MARTINELLI, Martino; SIQUEIRA, Sergio Freitas de; STERNICK, Eduardo Back; RASSI JR., Anis; COSTA, Roberto; RAMIRES, Jose Antonio Franchini; KALIL FILHO, Roberto
    Assessing the efficacy of implantable cardioverter-defibrillators (ICD) in patients with Chagas' heart disease (ChHD) and identifying the clinical predictors of mortality and ICD shock during long-term follow-up. ChHD is associated with ventricular tachyarrhythmias and an increased risk of sudden cardiac death. Although ChHD is a common form of cardiomyopathy in Latin American ICD users, little is known about its efficacy in the treatment of this population. The study cohort included 116 consecutive patients with ChHD and an ICD implanted for secondary prevention. Of the 116 patients, 83 (72%) were men; the mean age was 54 +/- 10.7 years. Several clinical variables were tested in a multivariate Cox model for predicting long-term mortality. The average follow-up was 45 +/- 32 months. New York Heart Association class I-II developed in 83% of patients. The mean left ventricular ejection fraction was 42 +/- 16% at implantation. Of the 116 patients, 58 (50%) had appropriate shocks and 13 (11%) had inappropriate therapy. A total of 31 patients died (7.1% annual mortality rate). New York Heart Association class III (hazard ratio [HR] 3.09, 95% confidence interval 1.37 to 6.96, p = 0.0064) was a predictor of a worse prognosis. The left ventricular ejection fraction (HR 0.972, 95% confidence interval 0.94 to 0.99, p = 0.0442) and low cumulative right ventricular pacing (HR 0.23, 95% confidence interval 0.11 to 0.49, p = 0.0001) were predictors of better survival. The left ventricular diastolic diameter was an independent predictor of appropriate shock (I-ER 1.032, 95% confidence interval 1.004 to 1.060, p = 0.025). In conclusion, in a long-term follow-up, ICD efficacy for secondary sudden cardiac death prevention in patients with ChHD was marked by a favorable annual rate of all-cause mortality (7.1%); 50% of the cohort received appropriate shock therapy. New York Heart Association class III and left ventricular ejection fraction were independent predictors of worse prognosis, and low cumulative right ventricular pacing defined better survival.

    Upper extremity deep venous thrombosis and pulmonary embolism after transvenous lead replacement or upgrade procedures
    (2020) ALBERTINI, Caio Marcos de Moraes; SILVA, Katia Regina da; LIMA, Marta Fernandes; LEAL FILHO, Joaquim Mauricio da Motta; MARTINELLI FILHO, Martino; COSTA, Roberto
    Background Venous obstructions are frequent in patients with transvenous leads, although related clinical findings are rarely reported. After lead replacement or upgrade procedures, these lesions are even more frequent, but there is still no evidence to support this observation. Aim To investigate the incidence and possible risk factors for upper extremity deep venous thrombosis (UEDVT) and pulmonary embolism (PE) after lead replacement or upgrade procedures. Methods Prospective cohort carried out between April 2013 and July 2016. Preoperative evaluation included venous ultrasound and pulmonary angiotomography. Diagnostic exams were repeated postoperatively to detect the study outcomes. Multivariate logistic regression models were used to identify prognostic factors. Results Among the 84 patients included, 44 (52.4%) were female and mean age was 59.3 +/- 15.2 years. Lead malfunctioning (75.0%) was the main surgical procedure indication. Lead removal was performed in 44 (52.4%) cases. The rate of postoperative combined events was 32.6%, with 24 (28.6%) cases of UEDVT and six (7.1%) cases of PE. Clinical manifestations of deep venous thrombosis occurred in 10 (11.9%) patients. Independent prognostic factors for UEDVT were severe collateral circulation in the preoperative venography (odds ratio [OR] 4.7; 95% confidence interval [CI] 1.1-19.8; P = .037) and transvenous lead extraction (OR 27.4; 95% CI 5.8-128.8; P < .0001). Conclusion Reoperations involving previously implanted transvenous leads present high rates of thromboembolic complications. Transvenous lead extraction had a significant impact on the development of UEDVT. These results show the need of further studies to evaluate the role of preventive strategies for this subgroup of patients.

    Glocal Clinical Registries: Pacemaker Registry Design and Implementation for Global and Local Integration - Methodology and Case Study
    (2013) SILVA, Katia Regina da; COSTA, Roberto; CREVELARI, Elizabeth Sartori; LACERDA, Marianna Sobral; ALBERTINI, Caio Marcos de Moraes; MARTINELLI FILHO, Martino; SANTANA, Jose Eduardo; VISSOCI, Joao Ricardo Nickenig; PIETROBON, Ricardo; BARROS, Jacson V.
    Background: The ability to apply standard and interoperable solutions for implementing and managing medical registries as well as aggregate, reproduce, and access data sets from legacy formats and platforms to advanced standard formats and operating systems are crucial for both clinical healthcare and biomedical research settings. Purpose: Our study describes a reproducible, highly scalable, standard framework for a device registry implementation addressing both local data quality components and global linking problems. Methods and Results: We developed a device registry framework involving the following steps: (1) Data standards definition and representation of the research workflow, (2) Development of electronic case report forms using REDCap (Research Electronic Data Capture), (3) Data collection according to the clinical research workflow and, (4) Data augmentation by enriching the registry database with local electronic health records, governmental database and linked open data collections, (5) Data quality control and (6) Data dissemination through the registry Web site. Our registry adopted all applicable standardized data elements proposed by American College Cardiology/American Heart Association Clinical Data Standards, as well as variables derived from cardiac devices randomized trials and Clinical Data Interchange Standards Consortium. Local interoperability was performed between REDCap and data derived from Electronic Health Record system. The original data set was also augmented by incorporating the reimbursed values paid by the Brazilian government during a hospitalization for pacemaker implantation. By linking our registry to the open data collection repository Linked Clinical Trials (LinkedCT) we found 130 clinical trials which are potentially correlated with our pacemaker registry. Conclusion: This study demonstrates how standard and reproducible solutions can be applied in the implementation of medical registries to constitute a re-usable framework. Such approach has the potential to facilitate data integration between healthcare and research settings, also being a useful framework to be used in other biomedical registries.
