• New Leadless Pacemaker Promising in Safety, Efficacy - Medscape, 12/3/21
• Medtronic Recall of Almost 240,000 ICDs Is Class I, FDA Says - Medscape, 4/12/21 - "Physicians were notified of the company's recall in early February. It covered implantable cardioverter defibrillator (ICD) and cardiac resynchronization therapy-defibrillator (CRT-D) models Evera, Viva, Brava, Claria, Amplia, Compia, and Visia distributed from August 31, 2012 to May 9, 2018 ... The devices could be subject to "an unexpected and rapid decrease in battery life" due to a possible short circuit that could lead to a device-replacement alert "earlier than expected." Some devices may experience full battery depletion "within as little as one day" after such an alert."
• Newer iPhones Disable Implanted Defibrillators - Medscape, 2/1/21 - "Tests were performed on a patient wearing a Medtronic ICD ... "Once the iPhone was brought close to the ICD over the left chest area, immediate suspension of ICD therapies was noted," according to the authors of the study. The functional loss of the ICS persisted for the duration of proximity. It was reproduced multiple times and with multiple phone positions."
• The Benefit of Prophylactic Implantable Cardioverter Defibrillator Implantation in Asymptomatic Heart Failure Patients With a Reduced Ejection Fraction - Am J Cardiol. 2019 May 29 - "Recommendations for prophylactic implantable cardioverter defibrillator (ICD) implantation in asymptomatic heart failure patients with a reduced left ventricular ejection fraction (LVEF) differ between guidelines. Evidence on the risk of appropriate device therapy (ADT) and death in New York Heart Association (NYHA) class I patients is scarce ... To evaluate the incidence of ADT and mortality, NYHA-I was compared with NYHA-II-III using Cox regression analysis. During a follow-up of 4.1 ± 2.4 years, 33% of the NYHA-I patients received ADT compared with 20% of the NYHA-II-III patients (hazard ratio 1.5, 95% confidence interval 1.04 to 2.31, p = 0.03). No differences in mortality were observed (hazard ratio 0.70, 95% confidence interval 0.49 to 1.07, p = 0.10). Additional analyses showed no difference in time to ADT excluding CRT patients (ICD-NYHA-I patients vs ICD-NYHA-II-III patients, p = 0.17) and comparing ischemic and nonischemic cardiomyopathy NYHA-I patients (p = 0.13). Multivariable Cox regression analyses showed that NYHA class was the strongest independent predictor of ADT. In conclusion, primary prevention NYHA-I ICD patients showed a higher incidence of ADT compared with NYHA-II-III ICD patients. These results strongly suggest that primary prevention NYHA-I patients with a LVEF ≤35% are likely to benefit from ICD therapy and should not be excluded from a potentially life-saving therapy"
