lv pacemaker lead placement*******CRT is a mainstay in the management of heart failure patients with electrical dyssynchrony. LV lead positioning remains an important variable that predicts response .
The present article reviews the literature on image-guided cardiac resynchronization therapy (CRT) studies. Improved outcome to CRT has been . We have developed an innovative technique for intraseptal left conduction system pacing. 3 The common features of this implantation technique are shown in Figure 1 and summarized as follows: (1) .
Implantation of the left ventricular (LV) pacing lead is one of the determinants of CRT response. This procedure includes several challenging technical issues and .
Although direct lead placement with stylet-guided pacemaker leads may be feasible in some patients, most implants require intubation of the coronary sinus with a .lv pacemaker lead placement Although direct lead placement with stylet-guided pacemaker leads may be feasible in some patients, most implants require intubation of the coronary sinus with a . Get an in-depth look at the precise positioning of left ventricular leads in biventricular pacemakers. This instructional video, extracted from our Pacemaker .lv pacemaker lead placement left ventricular implantationAn optimal placement of the left ventricular (LV) lead appears crucial for the intended hemodynamic and hence clinical improvement. A well-localized target area and tools . The LV lead location was classified along the short axis into an anterior, lateral, or posterior position and along the long axis into a basal, midventricular, or apical region. The primary end point of MADIT .
However, LV epicardial lead placement is associated with increased rates of complications such as renal insufficiency and infections. 5 With the advancements made in tools and techniques for LV lead delivery, the implanting electrophysiologist now has a variety of approaches to adopt when encountering challenging LV lead implants to .
The connector of the lead was tunnelled submuscularly to the device pocket and the pacemaker. Patients were generally extubated in the operating room and observed in the cardiac surgery recovery unit. . Surgical LV lead placement offers the advantage of direct access to the lateral left ventricular wall. While uncommon, inadvertent LV lead placement is a potentially devastating complication of pacemaker implantation. Appropriate analysis of the paced QRS pattern on ECG and post-implantation chest radiograph may reduce morbidity and mortality by promoting early recognition and treatment. However, the nonapical RV lead placement was not significantly different between the various LV lead locations. LV Lead Location and Baseline Clinical Characteristics The LV lead position was assessed in 799 patients (55% patients ≥65 years of age, 26% female, 10% LVEF ≤25%, 55% ischemic cardiomyopathy, and 71% LBBB) .

This changes in cardiac hemodynamics cause left ventricular (LV) cellular abnormalities (both at a gross and ultrastructural level) may lead to ventricular remodeling which is associated with a higher risk of development of LV systolic dysfunction, heart failure, and atrial fibrillation. 1 Retrospective analysis of the Mode Selection Trial (MOST) . In the reported case, LV lead placement was recognized about 3 months after implantation and the percutaneous lead extraction was performed without complications. Consent The authors confirm that written consent for submission and publication of this case report including images and associated text has been obtained . How to: a practical guide to cardiac conduction devices on . There is increasing evidence that LV lead placement in the region of the latest activation . Medium-term effects of septal and apical pacing in pacemaker-dependent patients: a double-blind prospective randomized study. Pacing Clin Electrophysiol. 2014 Feb; 37 (2):207–14. [PMC free article] [Google Scholar] Mond has developed a specially shaped stylet (Mond’s stylet) for easier implantation of the lead into the inter-ventricular septum. 22 Mond’s stylet has firstly, a generous curve in the distal 5–6 cm of stylet (primary curve). Then the terminal 2 cm is bent with 90 ° angle to primary curve to create a swan neck shape (secondary curve) (Fig. 2 A). 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. Although placement of the LV lead to the PL position has been proposed as the first priority, AL lead location results in HF improvement comparable with that in PL lead location in our study. We found similar HF improvement regardless of whether LV leads were placed in the basal, mid, or apical left ventricle.
Later, we passed a 90-cm bipolar LV pacing lead (containing 2 silicone tines) over the wire and placed it in the RV apex for RV pacing (Fig. 1B). The LV lead was connected to a Verity™ ADx 5156 Pacemaker (St. Jude Medical) in rate-modulated ventricular-based (VVIR) mode. After device analysis, the temporary pacemaker was removed.In CRT, the sometimes the LV lead is configured to pace from its tip (Cathode) to RV ring (anode) [LVtip – RVring]. The necessity for this situation arises when there are phrenic nerve capture issues. When the LV is paced from the tip of LV electrode, the RV ring is can cause anodal stimulation at high outputs.
Transvenous placement of permanent pacemaker leads has been established as a reliable and less invasive approach for permanent pacing. However, this technique might not be suitable or possible for every patient. Those with systemic venous anomalies, functional single ventricle, and small infants/children are better served with .
Cardiac perforation due to a pacemaker or defibrillator lead occurs at a rate of 0.4–2.0%. Since first described [ 1 ], the overall incidence has decreased significantly. The reported incidence of this complication has been as low as < 1 % to as high as 15% [ 2 - . Although rare, inadvertent placement of a pacemaker or defibrillator lead in the left ventricle can have serious consequences, including arterial thromboembolism and aortic or mitral valve damage or infection. 1–4 This article discusses situations in which lead malpositioning is likely to occur, how to prevent it, how to detect and correct it .
In cases of intravenous placement failure of the left ventricular (LV) lead for cardiac resynchronisation therapy (CRT) and obliteration of the left pleural space, the alternative approach of transthoracic placement by video-assisted thoracoscopic surgery (VATS) is difficult and not commonly practiced. Here, we present a simple technique for . Although direct lead placement with stylet-guided pacemaker leads may be feasible in some patients, . LV lead placement is eventually successful in more than 95% of patients and implant failures are more often due to insufficient support by the guiding catheter than by anatomical problems involving the anatomy of the ventricular CS .A new approach for overcoming the limitations of conventional CS LV lead positioning, is wireless stimulation of the LV; Wireless Cardiac Stimulation system (WiC ® S-LV (EBR Systems Inc. USA)).58,57,145 The WiC ® S-LV system may be implanted with any pacemaker system and consists of a subcutaneous pulse generator and an .

Consideration is also given to prospectively defining placement of the LV lead including surgical epicardial lead positioning.
Cardiac conduction devices | Radiology Reference Articleleft ventricular implantationDr. Miguel Gomes performs a Robotic assisted LV lead placement to help patients with severe heart disease have pacemakers implanted: 832.260.0500. . (Epicardial Pacemaker Leads) Cardiac resynchronization therapy is used when a patient’s heart beats irregularly. However, technical limitations, owing to coronary sinus and venous anatomy, result in a 10–15 % failure rate for left ventricular (LV) lead placement [7, 8]. Moreover, lead dislodgement contributes to an additional 5–10 % of late failures of left ventricular lead electrical capture . The atrial lead and right ventricular lead were implanted without problems; however, LV lead insertion failed because of very small cardiac veins. The generator was positioned in the left subclavicular pocket, and the pacemaker leads except the LV lead were connected. The pocket was closed, and epicardial LV lead insertion via VATS was .
