May inform surveillance for long-dwell Riata leads; leaves open whether routine fluoroscopic screening improves outcomes.

Fluoroscopic screening of asymptomatic patients with recalled Riata leads reveals a high, time-dependent rate of cable externalization (>20% at >5 years) that is associated with decreased R-wave amplitude.
Liu et al. (2012) conducted a cross-sectional in Asymptomatic patients implanted with the Riata lead (n=245). Riata lead was evaluated on Lead separation (inside-out abrasion). Fluoroscopic screening of asymptomatic patients with the Riata lead revealed a 21.6% incidence of lead separation, with rates increasing to 26% at >5 years of dwell time.
