A Better Method for Preventing Adverse Clinical Events Caused by Implantable Cardioverter-Defibrillator Lead Fractures? |...
Fracture of a transvenous high-voltage ICD lead was first observed in the original CPI Endotak model in 1988.8 Patients who had this lead suffered multiple inappropriate shocks, and it was withdrawn from clinical trial. Since then, conductor fractures and insulation disruption have challenged engineers and physicians to develop improved designs and implant techniques. Progress has been made, but not without setbacks. The Medtronic Transvene lead, a coaxial polyurethane design introduced in 1993 and implanted in ,24 000 patients, exhibited both insulation degradation and conductor fractures; these failures typically appeared ≥4 years after implant and most commonly presented as inappropriate shocks.9 A mismatch between the terminal pin of the Boston Scientific Endotak DSP and the pulse generator connector header resulted in insulation and conductor defects when the pin punctured the lead; again, inappropriate shocks were the usual consequence. Surgical methods have ...http://circ.ahajournals.org/content/118/21/2117
Duration of Discharge of Neuromuscular Incapacitating Device and Inappropriate Implantable Cardioverter-Defibrillator...
Neuromuscular-incapacitating devices (NID) are being used increasingly worldwide by law-enforcement authorities to restrain violent behavior.1 Electrical noise-related, inappropriate detection by implantable cardioverter-defibrillator (ICD) has been documented.2,3 Detection of NID discharge by ICD has been described,4,5 but the effects of duration of NID discharge and ICD detection and therapy have not been established. The authors hypothesized that a longer duration of NID energy might lead to shocks from the defibrillator.4. With the approval of the animal care committee of our institution, we tested this hypothesis in a pig implanted with Medtronic 7275 GEM III DR ICD. The method used for performing the experiment in a pig model has been described previously.6 In the present study, we used subcutaneous insertion of the darts. Particular attention was given to ensure that the darts were in the subcutaneous tissue and not any deeper, to avoid any possibility of direct stimulation through the ...http://circ.ahajournals.org/content/115/20/e472
Abstract 2140: Infrequent Need for Pacing Following Implantable Cardioverter-Defibrillator Shocks: Analysis of the Sudden...
Background: Implantable cardioverter-defibrillators (ICD) are routinely programmed to pace after a shock to prevent possible asystole. In those with no prior history of bradycardia, there is little data regarding the prevalence and characteristics of those who use post-shock pacing (PSP).. Methods: We analyzed the occurrence of pacing within the first nine beats after the first successful ICD shock for ventricular tachycardia (VT) or ventricular fibrillation (VF) in the Sudden Cardiac Death in Heart Failure Trial (SCD-HeFT). All ICDs were single lead with the first PSP delivered at 1400msec and all subsequent stimuli delivered at 1200msec. We excluded patients with pacing during pre-shock rhythms and those who had pacing rates different than the protocol default rate of 50bpm (1200 msec).. Results: There were 2521 patients enrolled in SCD-HeFT, of which 811 received an ICD. A total of 153 shock events were examined; 36 (23.5%) had at least one of the first ...http://circ.ahajournals.org/content/118/Suppl_18/S_674.1

Postoperative lead-related complications in patients with nonthoracotomy defibrillation lead systems | JACC: Journal of the...
Results Twenty-seven patients (15.9%) were diagnosed with a lead-related complication that either extended the initial hospital period or led to a second hospital admission. Complications included endocardial lead or subcutaneous defibrillation patch dislodgment in eight patients (4.7%), which was diagnosed between 2 and 345 days after implantation; endocardial or subcutaneous patch lead fracture in six (3.5%), which was diagnosed between 53 and 600 days after implantation; subcutaneous patch mesh fracture in one, which was diagnosed at 150 days after implantation; subclavian vein thrombosis in three (1.8%), which was diagnosed at 2 to 50 days after implantation; and unacceptably elevated defibrillation threshold (within 5 J of maximal device output) in nine (5.3%), which was documented at one of the two postimplantation evaluations in eight patients or at the time of failure to terminate a spontaneous ventricular tachycardia in one. Seventeen of the 27 patients required reoperation for ...http://www.onlinejacc.org/content/26/3/776
Abstract 19495: Extraction of St. Jude Riata Leads: Clinical Experience and Outcomes at a High Volume Extraction Center |...
Objectives: St. Jude Riata leads were recalled December 2011. We sought to compare our procedural experience and outcomes extracting the Riata defibrillator lead with extraction of non-Riata leads.. Methods: Data was obtained from 2008-2012 from a prospective lead extraction registry established at a single tertiary referral high volume extraction center. The experience with Riata extraction was analyzed and compared with extractions performed on non-Riata leads in a cohort of patients matched for comorbidities using the Charlson comorbidity index.. Results: A total of seventy-two patients had Riata lead extractions, 35 for electrical malfunction and 37 for infections. There were 53 males (73.6%) and 19 females (26.4%). Flouroscopy before extraction revealed exteriorized cables on 15 patients (20.8%). Of patients with infections, 20 (54.1%) had vegetations ranging in size from 3-32 mm. Average age for Riata lead was 60 years old, and average ejection fraction (EF) was 42% +/- 8%. All leads were ...http://circ.ahajournals.org/content/126/Suppl_21/A19495

Ed Metzger from Southwest Ontario Veterinary Service, Does Prolonged Nursery Downtime Affect Bacterial Loads? - Swineweb.com -...
Sanitation measures such as cleaning, disinfection and downtime between production batches on pig farms are essential in preventing disease outbreaks. These measures may not eliminate all of the bacteria but a significant reduction in "infective pressure" can reduce the probability of disease. One of the questions that comes up from time to time is the potential benefit of longer downtime between batches. While we do know that downtime is an important factor for diseases such as PRRS and PED there a relatively few studies that have examined the effect of longer downtimes on bacteria in nursery units.. These Belgian researchers wanted to evaluated the potential benefit of a 10-day downtime period in pig nursery units on total aerobic flora, Enterococcus spp., Escherichia coli, fecal coliforms and methicillin resistant Staphylococcus aureus (MRSA). Three downtime periods of 10 days were monitored in each of 3 units. The microbiological load was measured before disinfection and at 1, 4, 7 and ...http://www.swineweb.com/ed-metzger-southwest-ontario-veterinary-service-prolonged-nursery-downtime-affect-bacterial-loads/
Pediatric Lead Extractability and Survival Evaluation (PLEASE) - Full Text View - ClinicalTrials.gov
The recognition that ICD therapy in children can be life-saving, as well as the development of smaller devices and leads, are resulting in increased ICD implantation in the pediatric and young adult populations. However, ICD lead survival in this patient group is suboptimal. Lead extraction is technically difficult and has substantial morbidity. Recently, improved ICD lead designs have been released and are currently being utilized. While the development of transvenous ICD leads has allowed for less invasive implantation, the long-term presence of these leads carries some risks. When a lead becomes infected or causes patient morbidity, it must be removed. Because of the larger caliber of ICD leads and the presence of uninsulated shocking coils, non-functional ICD leads usually warrant removal to avoid future mechanical or electrical lead interactions. The larger size of ICD leads is of concern in this younger population, particularly with regard to avoiding the accumulation of implanted ...https://clinicaltrials.gov/ct2/show/NCT00335036?cond=%22Romano-Ward+syndrome%22+OR+%22Long+QT+Syndrome%22&rank=14

Hiccups and Dysphonic Metallic Voice | Circulation
Twiddler syndrome refers to a rare complication observed in patients with implanted pacemakers or defibrillators that causes device malfunction. The condition arises as a result of the patient's conscious or unconscious manipulation of the device, causing its rotation in the pocket, resulting in torsion and dislodgment of the implanted lead(s).. A 65-year-old obese woman with idiopathic dilated cardiomyopathy and diabetes mellitus had undergone implantation of a biventricular implantable cardioverter-defibrillator (CRT-D, Medtronic Insync Maximo 7304) with the positioning of 3 leads: a passive bipolar lead in the auricula of the right atrium (Medtronic Capsure Z Novus 5554), a bipolar, single-coil, screw-in lead (Medtronic Sprint 6931) in the apex of the right ventricle (RV), and a unipolar left-ventricular (LV) pacing lead (Medtronic Attain 4193) in an anterolateral tributary of the coronary sinus..

Summary of Medical device failure expertise
Catheters and sutures are examples of simple devices that help patients but where failure can imperil them. Catheters are simply tubes providing sustenance or drugs, and are often intravenous. However, they bypass the body's normal defences to external threats such as bacteria and viruses. Should they fracture, then bacteria present on the tube have direct access to the body and can cause life-threatening infections. Air bubbles can also form and enter the body with possible fatal results.. New polymers have been introduced for catheters, but these may be sensitive to common hospital fluids such as cleaning agents used to reduce the infection problem. Environmental stress cracking and stress corrosion cracking are two problems manufacturers should test against when developing new products. But testing is not always done.. Much information is available in the literature. But even with the ready availability of the internet, careful literature searches have not always been performed by the ...http://www.jspubs.com/experts/bae/sample.cfm?id=44
Potential benefits of remote follow-up of ICD patients: the EVATEL trial - Healthcanal.com : Healthcanal.com
Currently," explains investigator Dr Philippe Mabo form the University Hospital of Rennes, France, "regular in-clinic follow-up must be performed every three months, according to manufacturer guidelines. But there are two drawbacks to the in-clinic follow-up - they're time-constrained for both the patient and the clinic, and there's no link between the time of the appointment and the clinical event or device malfunction. So there's a clinical need to consider new follow-up strategy.". In response, several manufacturers have developed new technologies which allow the remote transmission of information from the device and on its therapeutic effect. Critical data can be transmitted at any time on system integrity or unexpected events - for example, lead integrity, battery status or ineffectively delivered therapy. Data stored in the device are transmitted by phone from the patient's home to the implant centre, with website access to the data.. "In this context," said Dr Mabo, "remote device ...https://www.healthcanal.com/blood-heart-circulation/20105-potential-benefits-of-remote-follow-up-of-icd-patients-the-evatel-trial.html
Brody Davis - Wikipedia
Brody Davis is a fictional character created by Jason Katims for the 1999-2002 American science fiction television series Roswell. He is portrayed by actor Desmond Askew. Davis is a millionaire who takes over ownership of the UFO Center where Max Evans works. On a number of occasions, he claims to have been abducted by aliens. He tells Maria DeLuca that, in essence, his mind would go blank and he would awaken a few days later lacking knowledge of where he had been or what he had been doing. In reality, his body was being used as a vessel by aliens to come to Earth. He later tries to develop a device that will "open a part of his brain" that he believes contains memories of where he had been taken. This device malfunctions and the resulting shock reveals previously unknown memories to him, which leaves him confused and afraid. After this happens, he takes Max Evans, Tess Harding, Liz Parker, Maria, her mother and her cousin hostage. Max is able to heal the damage to part of Brody's brain using ...https://en.wikipedia.org/wiki/Brody_Davis
