Surgical LV lead placement offers the advantage of direct access to the lateral left ventricular wall. Direct visualisation provides an almost unrestricted opportunity to implant the leads at the optimal target site, so that the pre-determined lead position was achieved in . To facilitate stable left ventricular (LV) lead placement, it is practical first to place the right ventricular (RV) pacing lead and then to advance the LV lead into the coronary sinus (CS) branch, leaving the sheath in place. After the right atrial (RA) lead is positioned, the LV lead guiding sheath is removed, and the LV lead is sutured in place.
The LV lead position was assessed in 799 patients by means of coronary venograms and chest x-rays recorded at the time of device implantation. The LV lead location was classified along the short axis into an anterior, . Purpose of Review Cardiac resynchronization therapy (CRT) represents a well-established and effective non-pharmaceutical heart failure (HF) treatment in selected patients. Still, a significant number of patients remain CRT non-responders. An optimal placement of the left ventricular (LV) lead appears crucial for the intended hemodynamic and hence clinical .ACUITY™ X4 Quadripolar LV Leads. New Solutions. Meaningful Outcomes. ACUITY™ X4 Quadripolar LV leads are the first and only LV leads uniquely designed to promote non-apical pacing options, helping physicians to pace from an optimal site for improved CRT response. Cardiac resynchronization therapy (CRT) is a modality of cardiac pacing that provides simultaneous or nearly simultaneous electrical activation of the LV and right ventricle (RV) via stimulation of the LV and RV (biventricular pacing) or LV alone. CRT devices pace the LV via a lead placed in a branch of the coronary sinus or, less commonly, via .
CRT Leads Overview. Our broad choices of leads to navigate diverse anatomies enhance the chance of success during the implant procedure. Designs are available for stability in different vein sizes and programming options to avoid phrenic nerve stimulation. Attain Stability Quad; Attain Performa; Attain Ability The LV lead location was classified in 797 patients with CRT-D: 569 patients with left bundle branch block (LBBB) and 228 with non-LBBB. Leads were classified into apical (n = 83) and nonapical (n = 486), with the nonapical LV leads further categorized into anterior (n = 99) and posterior/lateral (n = 387) within LBBB. .
ABSTRACT. Expanding indications for cardiac resynchronization therapy (CRT) and emerging data on the importance of targeted left ventricular (LV) lead placement have resulted in renewed focus on refining implantation technique. Many implanting physicians use an “over-the-wire” approach to LV lead placement that may not provide enough support for lead .
ACUITY™ X4 Quadripolar LV Leads - Indications, Safety and Warnings. The Boston Scientific ACUITY X4 lead is a steroid-eluting (dexamethasone acetate) IS4 quadripolar lead.
Markedly increased LV voltages: huge precordial R and S waves that overlap with the adjacent leads (SV2 + RV6 >> 35 mm). R-wave peak time > 50 ms in V5-6 with associated QRS broadening. LV strain pattern with ST depression and T-wave inversions in I, aVL and V5-6. Inadvertent placement of a ventricular lead into the left ventricle (LV) is a rare complication during cardiovascular implantable electronic device (CIED) implantation. In a retrospective study of 2579 patients undergoing CIED implantation, 6 patients (0.34%) had inadvertent lead malposition in the left heart—4 in the LV and 1 each in left atrium and .

In-patient heart failure hospitalization rates and LV lead surgical revisions were 54% lower for the quadripolar group (0.15/patient-year than for the bipolar LV group (0.32/patient-year) (p = 0.04). 5; The hospitalization rate reduction was accompanied with statistically significant cost savings of 62% (p = 0.016). 5 LV lead threshold management according to manufacturer. Fig. 1 Legend: Panel A: LV automatic threshold test for Medtronic devices (Vector Express), displaying loss of capture with intrinsic RV conduction. The channels displayed are: EGM 1 = atrial channel; ECG = the “large” RV dipole (coil to can) with A-V markers; EGM 3 = the “LV cathode .
Optimal LV lead positioning within the coronary sinus tributaries is an important determinant of CRT response. Randomized trials have demonstrated superior CRT response and lower mortality and hospitalizations for heart failure when an echo-guided approach is used to target the LV lead to the site of the latest mechanical activation [6, 7].The stimulation polarity is programmable in the left ventricle by choosing a quadripolar (4 electrodes) or non-quadripolar (1 or 2 electrodes) lead. If a unipolar LV lead is implanted, a single configuration (LV tip à RV ring or RV coil) might .INSERTION OF LEAD(S) 33216 Insertion of single lead 5.62 7 NA 33217 Insertion of two leads 5.59 0 NA 33224 Insertion of pacing LV lead, with attachment to previously placed pacemaker or ICD generator including revision of pocket, removal, insertion and/or replacement of existing generator 9.04 9 NA +33225Quartet™ LEFTfiHEART LEADS Family of LV Leads Physical Specifications MODELS 1458Q 1456Q 1457Q 1458QL Parameter Description Description Description Description Connector IS4-LLLL IS4-LLLL IS4-LLLL IS4-LLLL Lead Length 75; 86; 92 cm 75; 86 75; 86 cm 75; 86 Maximum Lead Size 5.1 F (1.70 mm/0.067”) at the ring electrode

A variety of imaging and mapping methods have been used by several groups to investigate the effectiveness of targeted LV lead placement in CRT, as documented in Online Supplemental Table A and Figure 1.This article aims to provide a comprehensive overview of the different techniques used for LV lead placement and evaluate the scientific evidence .The ECG leads. Before discussing the ECG leads and various lead systems, we need to clarify the difference between ECG leads and ECG electrodes.An electrode is a conductive pad that is attached to the skin and enables the recording of electrical currents. An ECG lead is a graphical description of the electrical activity of the heart and it is created by analyzing several electrodes.

Cardiac resynchronization therapy (CRT) reduces both morbidity and mortality in selected patients with heart failure who remain symptomatic despite optimal medical therapy, exhibit intraventricular conduction delay, and have left ventricular (LV) dysfunction ().However, a significant proportion of patients fail to achieve benefit from CRT (). Aims: to study the technical performance of epicardial left ventricular (LV) leads placed via video assisted thoracic surgery (VATS), compared to transvenously placed leads for cardiac resynchronization therapy (CRT). Methods: From 2001 until 2013, a total of 644 lead placement procedures were performed for CRT. In the case of unsuccessful transvenous LV .
