Lead dwell time was similar in the 2 groups (5.7 5 years vs 5.6 4.3 years; P = .95). The younger cohort tended to require femoral extraction techniques more frequently (9.5% vs 4.4%; P = .055). Extraction procedural success (group 1: 94.1%, group 2: 94.9%; P = .792), major complications (group 1: 0%, group 2: 1.3%; P = 1), and periprocedural mortality (group 1: 0%, group 2: 0.86%; P = 1) were similar in the 2

A lead is meant to be permanent, but sometimes problems arise that require it to be removed or replaced. This procedure is called lead extraction. Part of UCSF's nationally renowned heart care service, our lead extraction program is led by Dr. Byron Lee, who has been doing lead extractions since 2000

In some cases, abstractionrecombination can lead to still larger rings. In the example illustrated, 1,8-hydrogen atom extraction leads to the formation of a seven-membered ring product (119; equation 42). 39 The 1,7-diradical would be thermodynamically favored because of the radical-stabilizing ability of the two sulfur atoms.The reaction may not, however, proceed by direct 1,8-abstraction

Pacemaker or ICD Lead Extraction. In pacemakers and ICD, the leads are inserted into a lead under the collar bone and advanced into the heart. The body tries to heal any objects that are inserted into it and gradually the leads become coated with fibrous tissue. Over time the fibrous tissue may become attached to the heart and the blood vessels

Mar 16, 2018 Lead dysfunction was the second most frequent reason for lead extraction in the ELECTRa registry, amounting to 38.1% of cases. 4 Causes for lead dysfunction may be lead fracture or insulation failure resulting in issues with lead impedance, sensing or capture. In some cases, the electrical parameters may still be normal, but the integrity of

Mar 15, 2021 Lead age, coradial bipolar leads, passive leads, and leads without polyurethane insulation were predictive of pacemaker lead break and could increase difficulty of lead extraction. When leads being extracted are old or passive, coradial, or without polyurethane, we should be careful of the risks of lead break and consider a femoral approach and

Mar 01, 2021 Transvenous lead extraction (TLE) plays a critical role in managing patients with cardiovascular implantable electronic devices. Mechanical TLE tools, including rotational sheaths, are used to overcome fibrosis and calcification surrounding leads. Prospective clinical data are limited regarding the safety and effectiveness of use of mechanical TLE devices, especially rotational tools

Lead extraction. Recently, comprehensive endovascular techniques have been developed for pacemaker lead extraction.2, 4, 5 In the superior vena cava approach, a locking stylet is introduced into the lead and locked close to the distal electrode in order to apply traction directly to the tip.6 If gentle traction is not successful, telescoping sheaths can be advanced over the lead to disrupt
