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.A prospective clinical study was conducted to investigate the safety and effectiveness of these new leads in 27 countries.Cardiac resynchronization therapy with defibrillator candidates were enrolled (mean age 68 years; 71% men). All implanted subjects were followed...
