The industry’s only quadripolar LV lead family that offers dual fixation through .
The Quartet 1458Q left ventricular (LV) heart lead with the Quadra Assura CRT-defibrillator (CRT-D) or any market-approved CRT-D device with quadripolar pacing capabilities (referred to as quadripolar CRT-D device system) provides vector selection from 4 pacing electrodes on the LV lead, thereby providing up to 10 different pacing configurations using the .Quartet ™ left ventricular lead is a quadripolar pacing lead with three Titanium Nitride (TiN) coated platinum/iridium ring electrodes and one tip electrode. The Quartet lead provides bipolar sensing and pacing using any two of the four electrodes, cross-chamber pacing and sensing using any one of the four LV BackgroundIn cardiac resynchronization therapy (CRT), quadripolar (QUAD) left ventricular (LV) leads are less prone to postoperative complications than non‐QUAD leads. Some studies have suggested better clinical outcomes. Methods and ResultsClinical events were assessed in 847 patients after CRT‐pacing or CRT‐defibrillation using either QUAD (n=287) or . The introduction of quadripolar leads with additional pacing vectors has reduced lead‐related complications and improved clinical outcomes for patients compared with bipolar LV leads and have now become the lead of choice for most operators. 5 Despite this, LV lead displacement is a common postprocedure complication with estimated rates .
The quadripolar LV lead (Quartet 1458Q; St. Jude Medical, Saint Paul, MN) was placed in one of the coronary veins overlying the LV free wall. A site in the lateral, anterolateral, or posterolateral position was preferred. After electrophysiological measurements, theMoreover, the CRT response rate (using the CCS) at 3 months during standard Bi-V pacing with the Quartet quadripolar LV lead in this trial was marginally superior, at 77%, than the 6-month response rate of 74% (using the same .
The differences between the QLV intervals of the St. Jude Medical Quartet lead (D to F) are notably larger (152, 162, 175, and 179 ms). LAO = left anterior oblique; LV = left ventricular; RAO = right anterior oblique; RV = right ventricular. .
