Other approaches for non-responders or failed CRT include surgical epicardial LV lead implant and transseptal endocardial LV lead placement. Surgical technique is more invasive than percutaneous one, as it requires a minithoracotomy and can be challenging in patients with prior cardiac surgery with consequent pericardial adhesions.

Trans-Fontan baffle placement of an endocardial systemic ...

ing system, with epicardial cpt code for epicardial lv lead placement bipolar leads placed on the right atrium and the anterior apical portion of the right ventricle (RV), and a unipolar lead on the apical posterior LV, tunneled to an abdominal generator. The patient subsequently developed failing Fontan phys-iology, presenting at …

A proposed technique for right ventricular septal pacing

The confounding effects of possible RV lead displacement and discordant LV lead placement, due to anatomical factors makes interpretation difficult. Rönn et al using a randomised design in 33 patients with classical CRT indications could not show a difference between apex and RVOT RV lead positioning in endpoints of EF, QoL, peak oxygen uptake ...

Seth J. Worley, Kenneth A. Ellenbogen, in Clinical Cardiac Pacing, Defibrillation and Resynchronization Therapy (Fourth Edition), 2011. Replacement of Extracted or Dislodged Lead. Left ventricular leads are often easy to extract. However, when leads have been in place for over 3 months, partial or total occlusion of the main CS and target veins is common. 81 Using venoplasty, Zucchelli et al ...

Biventricular pacing systems were implanted with LV lead placement in epicardial veins via the coronary sinus in 67 patients and in the epicardium by surgery in 2 patients. LV leads were positioned as follows: posterolateral or lateral in 60 and anterior or anterolateral in 9.

Failure to implant a transvenous LV lead adds morbidity to the procedure as it may require surgical placement of a LV epicardial lead via a mini-thoracotomy. Maneuvering the LV lead into an optimal position is technically challenging because of anatomical obstructions such as valves in the CS, stenosis of the proximal portion of the target ...

Without this life-saving therapy, the dangerously rapid rhythm could lead to death in just minutes. An implanted CRT-D system. cpt code for epicardial lv lead placement Your CRT Device Battery. Just like any battery, the battery in your CRT-P or CRT-D will run out over time. Since the battery is permanently sealed inside your device, it can’t be replaced when its energy is depleted.

The leads were tunneled subcutaneously to the generator pocket. A new St. Jude biventricular pacemaker generator was then reconnected to the transvenous atrial and ventricular leads as well as to the epicardial lead. The generator was again interrogated, and the thresholds and impedances of all leads were found to be adequate.

cpt code for epicardial lv lead placement Optimal placement of the LV pacing lead has been shown to be a crucial determinant of CRT response [6-8]. The ImagingCRT study is a randomized trial designed to test the hypothesis that multimodality imaging guided LV lead positioning can increase the response rate to CRT as compared with standard LV lead placement.
