Multicenter Study Clinical Trial
Performance of a novel left ventricular lead with short bipolar spacing for cardiac resynchronization therapy: primary results of the Attain Performa quadripolar left ventricular lead study.
The Medtronic Attain Performa quadripolar leads provide 16 pacing vectors with steroid on every electrode. This includes a short bipolar configuration between the middle 2 electrodes. ⋯ This large multicenter study demonstrated a high success rate for the implantation of Attain Performa quadripolar LV leads with a low complication rate. The PCT was low and stable over time. A low rate of postimplantation PNS was observed, and cases of PNS were readily resolved with reprogramming. Nonstandard vectors were often used for LV pacing.

Randomized Controlled Trial Multicenter Study
MRI scanning in patients with new and existing CapSureFix Novus 5076 pacemaker leads: randomized trial results.
Magnetic resonance imaging (MRI) can be safely performed in patients with magnetic resonance (MR)-conditional pacemaker systems but remains relatively contraindicated with non-MR-conditional pacemaker systems. ⋯ MRI scans can be performed safely without positioning restrictions in patients with Medtronic CapSureFix Novus 5076 leads connected to an MR-conditional pacemaker.
