Dr. Francesco Zanon of Italy and Dr. Pugashendhi Vijayaramen of the Geisinger Clinic in Pennsylvania report on the long term performance and safety of 884 patients implanted between 2004 and 2016.
The first 368 were implanted using a deflectable delivery system while for the next 476 patients a fixed curve delivery system was used.There was a significant difference in both the capture threshold and in the complication rate between the two groups,with the data strongly favoring the fixed curve system.
Complications were fewer in the fixed curve group (11.9 % and 4.2%) and the capture threshold was lower (2.4 volts versus 1.7 volts)The complication rate difference could at least in part been due to the learning curve as the fixed curve system was used later.
