- The Medtronic Sprint Fidelis lead family has a concerning rate of premature lead failure, prompting an investigation into potential risk factors related to the implantation technique.
- A study reviewed the implantation data of 176 patients, finding that 5.7% experienced lead malfunctions, primarily characterized by inappropriate shocks or high impedance readings.
- The analysis identified right-sided implantation and subpectoral generator positioning as significant predictors of lead failure, suggesting that these factors should be considered in clinical decision-making for at-risk patients.
