  • Notes supplémentaires dans les données
    According to the holder of the product registration in Brazil (St. Jude Medical Brazil Ltda.), The silicone coating, which represents the most commonly used defibrillation electrode insulation material in the industry in the last 20 years, has been found to be vulnerable to abrasion. Due to this fact, the company began to discontinue the commercialization of Riata and Riata ST electrodes. For more information on the problem and the evaluations made by the manufacturer of the product, consult Anvisa's Technovigilance Unit is monitoring this case.
  • Cause
    Electrode cables may present loss of insulation over time at a higher rate than normal.
  • Action
    The company is discontinuing the commercialization of all models of silicone electrodes Riata and Riata ST. With regard to health professionals who are accompanying patients implanted with Riata and Riata ST silicone electrodes, it is recommended: (1) To continue to monitor the system implanted in their patient at regularly scheduled intervals, paying particular attention to diagnostic information related to the defibrillation electrodes. The frequency of personal and remote monitoring is a follow-up period of 3-6 months for CDI / CRT-D devices; (2) Review electrode measurements, including pace and impedance of high-voltage electrodes, according to their standard follow-up procedures, in particular by looking for significant changes from the last follow-up visits of the patient; (3) If electrode failure is suspected, consider using provocative tests - such as arm and shoulder movements and deep breathing during observation of surface ECG and intracardiac electrocardiograms with the programmer, which tests may reveal a problem (if any). Also consider additional evaluation of the system (eg x-ray or fluoroscopy); (4) Consider remote monitoring and advise their patients on the importance of contacting them if they experience any adverse events; (5) Prophylactic electrode explant is not recommended.

    “We are in constant communication with regulatory agencies and competent authorities worldwide which allows us to implement global recalls or in-country communication quickly and effectively,” Abbott, which now owns St. Jude Medical told ICIJ in a statement. In addition to sending global notices to physicians worldwide, we also make sure that product advisories are available online and classification of product recalls and product advisories are determined by global regulatory bodies which can impact the timing in any given country. MD companies follow varying regulations in different countries. In come countries software is not regulated so a recall in one country related to software would not be classified as a recall or field action in another. In addition, review cycles within the regulatory process can be different in each country which can impact communication and recall timing.
