Long-Term Technical Performance of the Osypka QT-5 Ventricular Pacemaker Lead.

Background: Lead-associated complications and technical issues in patients with cardiac implantable electronic devices are common but underreported in the literature.

Methods: All patients undergoing implantation of the Osypka QT-5 ventricular lead at the University Clinic St. Pölten between 1 January 2006 and 31 December 2012 were retrospectively analyzed ( = 211).

Safe performance of magnetic resonance of the heart in patients with magnetic resonance conditional pacemaker systems: the safety issue of the ESTIMATE study.

Background: No published data exist about the safety of diagnostic magnetic resonance (MR) of the heart performed in a larger series of patients implanted with MR conditional pacemakers (PM). The purpose of our study is to analyse safety and potential alterations of electrical lead parameters in patients implanted with the EnRhythm/Advisa MRI SureScan PM with 5086MRI leads (Medtronic Inc.) during and after MR of the heart at 1.
