Systematic chest X-ray screening reveals a high incidence (24.3%) of insulation breaches in Riata defibrillation leads, highlighting the need for careful monitoring of these devices.
Steinberg et al. (2012) conducted an observational in Patients with St-Jude Medical Riata defibrillation leads (n=284). 8F Riata defibrillation leads vs. Non-8F Riata leads was evaluated on Radiological lead defects (insulation breaches) (p=<0.001). Systematic chest X-ray screening revealed a 24.3% incidence of insulation breaches in Riata defibrillation leads, with defects occurring more frequently in 8F leads than others (31.4% vs 6.3%; P<0.001).
