conferenceObject Prospective study of thromboembolic events after reoperation in permanent artificial cardiac pacing(2018) ALBERTINI, C. M.; SILVA, K. R.; LEAL FILHO, J. M.; MARTINELLI FILHO, M.; COSTA, R.bookPart Infecçoes de dispositivos cardiacos eletrónicos implantáveis(2018) COSTA, Roberto; ALBERTINI, Caio Marcos de Moraes; NASSIF JR., Miguel; CREVELARI, Elizabeth Sartori; SILVA, Kátia Regina da- Quality of life in patients with implantable cardioverter-defibrillator: systematic review of randomized controlled trials(2018) SILVA, Katia Regina da; COSTA, Roberto; RODRIGUES, Clarissa Garcia; SCHASECHTER, Andi; NOBRE, Moacyr Cuce; PASSMAN, Rod; MARK, Daniel B.Background: Implantable cardioverter-defibrillator (ICD) therapy significantly improves the survival of patients who are at high risk for sudden cardiac death. However, it is unclear whether this survival is accompanied by impairment on quality of life (QoL). Objectives: This systematic review sought to describe whether ICD therapy, as compared with standard treatment, can have an impact on QoL outcomes. Methods: Extensive literature searches were carried out in PubMed, EMBASE, LILACS and Cochrane Library. Eligible studies were randomized controlled trials (RCTs) of ICD versus medical therapy that reported valid and reliable measures of QoL. Included studies were reviewed to determine baseline patient characteristics, mean duration of follow-up, questionnaires used to assess QoL and association between QoL scores and ICD shock therapy. Results: Seven studies, enrolling a total of 5,701 patients, were included in this review. The analyzed trials showed conflicting results about the impact of ICD on QoL outcomes. Among the secondary prevention studies, CIDS reported a clear benefit from ICD and AVID showed no difference between ICD and amiodarone groups. Of the primary prevention trials, AMIOVIRT, MADIT II, DEFINITE, and SCD-HeFT found no evidence of impaired QoL in patients with an ICD. Evidence for an association between ICD shocks and QoL was mixed and seemed to depend on the interval between shocks and QoL assessment. Conclusion: There was no evidence of impaired QoL in patients with an ICD. However, ICD patients must be educated of all possible risks and benefits, including transitory declines in QoL after ICD shocks.

The main consequence of these lesions is the difficulty in obtaining venous access for additional leads implantation. Objectives: We aimed to assess the prevalence and predictor factors of venous lesions in patients referred to lead reoperations, and to define the role of preoperative venography in the planning of these procedures. Methods: From April 2013 to July 2016, contrast venography was performed in 100 patients referred to device upgrade, revision and lead extraction. Venous lesions were classified as non-significant (< 50%), moderate stenosis (51-70%), severe stenosis (71-99%) or occlusion (100%). Collateral circulation was classified as absent, discrete, moderate or accentuated. The surgical strategy was defined according to the result of the preoperative venography. Univariate analysis was used to investigate predictor factors related to the occurrence of these lesions, with 5% of significance level. Results: Moderate venous stenosis was observed in 23%, severe in 13% and occlusions in 11%. There were no significant differences in relation to the device side or the venous segment. The usefulness of the preoperative venography to define the operative tactic was proven, and in 99% of the cases, the established surgical strategy could be performed according to plan. Conclusions: The prevalence of venous obstruction is high in CIED recipients referred to reoperations. Venography is highly indicated as a preoperative examination for allowing the adequate surgical planning of procedures involving previous transvenous leads.
