INTRODUCTION: The use of steroid elution (SE) electrode in a cardiac pacing lead is known to suppress myocardial inflammation to lower pacing thresholds (PTs). SE has been widely utilized on the distal electrode of left ventricular cardiac vein (LVCV) leads used in cardiac resynchronization therapy (CRT). However, no paired comparison in effect of SE has been studied in proximal electrodes of quadripolar LVCV leads. METHODS: We evaluated electrical performance and tissue responses of quadripolar LVCV lead electrodes with and without SE in two canine studies with a total of 14 canines...

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