Key result
A St. Jude Medical Riata 1570 right ventricular lead exhibited premature insulation failure with inner wire protrusion, causing elevated pacing threshold without impedance change.

May warrant closer Riata lead surveillance despite normal impedance; leaves open optimal monitoring and intervention strategies.
Case Report (n=1)
This case highlights a novel mechanism of premature insulation failure in Riata defibrillator leads that can occur without typical warning signs like impedance changes or inappropriate sensing.
Krebsbach et al. (2011) conducted a case report in Defibrillator lead failure (n=1). St. Jude Medical Riata 1570 right ventricular lead was evaluated on Insulation failure. A St. Jude Medical Riata 1570 right ventricular lead exhibited premature insulation failure with inner wire protrusion, causing elevated pacing threshold without impedance change.
