Heart (British Cardiac Society), Volume 99, Issue 10, 12 2 2013, Pages 722-728 Right ventricular function and survival following cardiac resynchronisation therapy. Leong DP, Höke U, Delgado V, Auger D, Witkowski T, Thijssen J, van Erven L, Bax JJ, Schalij MJ, Marsan NA
Objectives: Right ventricular (RV) function is an important prognostic marker in heart failure. However, its impact on all-cause mortality following cardiac resynchronisation therapy (CRT) independent of confounding factors has not been evaluated. Furthermore, evidence concerning the effect of CRT on RV function is limited. The study's aims were to: (1) assess the prognostic importance of RV function among CRT recipients, and (2) characterise RV functional change following CRT and its deter... Abstract

Radiation oncology (London, England), Volume 7, 24 4 2012, Pages 198 Management of radiation oncology patients with a pacemaker or ICD: a new comprehensive practical guideline in The Netherlands. Dutch Society of Radiotherapy and Oncology (NVRO). Hurkmans CW, Knegjens JL, Oei BS, Maas AJ, Uiterwaal GJ, van der Borden AJ, Ploegmakers MM, van Erven L, Dutch Society of Radiotherapy and Oncology (NVRO)
Current clinical guidelines for the management of radiotherapy patients having either a pacemaker or implantable cardioverter defibrillator (both CIEDs: Cardiac Implantable Electronic Devices) do not cover modern radiotherapy techniques and do not take the patient's perspective into account. Available data on the frequency and cause of CIED failure during radiation therapy are limited and do not converge. The Dutch Society of Radiotherapy and Oncology (NVRO) initiated a multidisciplinary ta... Abstract

American heart journal, Volume 164, Issue 2, 1 1 2012, Pages 146-152 The rationale and design of the Shockless IMPLant Evaluation (SIMPLE) trial: a randomized, controlled trial of defibrillation testing at the time of defibrillator implantation. Healey JS, Hohnloser SH, Glikson M, Neuzner J, Viñolas X, Mabo P, Kautzner J, O'Hara G, Van Erven L, Gadler F, Appl U, Connolly SJ
Defibrillation testing (DT) has been an integral part of defibrillator (implantable cardioverter defibrillator [ICD]) implantation; however, there is little evidence that it improves outcomes. Surveys show a trend toward ICD implantation without DT, which now exceeds 30% to 60% in some regions. Because there is no evidence to support dramatic shift in practice, a randomized trial is urgently needed. The SIMPLE trial will determine if ICD implantation without any DT is noninferior to implantation... Abstract

Marinskis G, van Erven L, Bongiorni MG, Lip GY, Pison L, Blomström-Lundqvist C, Scientific Initiative Committee, European Heart Rhythm Association
This survey analyses some details of follow-up of patients with cardiac implantable electronic devices (CIEDs) in 40 centres-the members of the European Heart Rhythm Association (EHRA) research network. Results of this survey show that practices of CIED follow-up are not homogeneous between EHRA research network centres, and recommended clinical evaluation of the patients regarding possible device up-grade is not always performed. Remote device monitoring appears to be an evolving practice, most... Abstract

In this case report we describe a short circuit in the Riata 1570 defibrillator lead (Riata 1570, St. Jude Medical, St. Paul, MN, USA) that was unsuspected owing to normal lead parameters until defibrillator threshold testing at the time of elective generator change. On this occasion, the short circuit manifested as unsuccessful defibrillation of ventricular fibrillation with immediate battery depletion. This report adds weight to existing concerns over narrow caliber leads, it draws attention t... Abstract

Remote monitoring of cardiac implanted electronic devices (CIED: pacemaker, cardiac resynchronisation therapy device and implantable cardioverter defibrillator) has been developed for technical control and follow-up using transtelephonic data transmission. In addition, automatic or patient-triggered alerts are sent to the cardiologist or allied professional who can respond if necessary with various interventions. The advantage of remote monitoring appears obvious in impending CIED failures and s... Abstract

Remote follow-up of implanted ICDs may offer a solution to the problem of overcrowded outpatient clinics. All major device companies have developed a remote follow-up solution. Data obtained from the remote follow-up systems are stored in a central database system, operated and owned by the device company and accessible for the physician or technician. However, the problem now arises that part of the patient's clinical information is stored in the local electronic health record (EHR) system... Abstract
