AI Article Synopsis

  • The study aimed to identify factors impacting the success of lead extraction using an excimer laser sheath, a process typically required for patients with implanted cardiac leads.
  • A total of 372 leads from 176 patients were analyzed, revealing a high success rate of 96%, with complications linked to the lead type and duration since implantation.
  • Key findings indicated that the use of a VDD-pacing lead significantly increased chances of procedural failure, highlighting the need for operators to be cautious when extracting these specific leads.

Article Abstract

Objectives: The purpose of this study was to examine the factors affecting the outcome of successful lead extraction with an excimer laser sheath, which have not been clearly elucidated.

Methods: Between January 2011 and December 2016 in our institution, 372 leads were intravenously extracted from 176 patients (mean age, 67 ± 15 years; 83% male) with the use of an excimer laser sheath. The mean time since lead implantation was 7.1 ± 6.7 years. Indications for this procedure were infection (76.1%), non-functional lead (11.3%), functional lead (9.7%) and others (2.9%).

Results: The clinically successful removal rate was 96%. The procedural failure group had a longer time from implantation (P = 0.01), longer fluoroscopy time (P < 0.01) and greater use of a single-lead atrioventricular synchronous (VDD) pacing lead (P < 0.01) compared to the clinical success group. The significant factors of clinical failure were the use of a VDD-pacing lead (odds ratio 30.9, 95% confidence interval 5.8-165; P < 0.01) and the time from first implantation (odds ratio 1.1, 95% confidence interval 1.0-1.3; P = 0.02). In addition, there was no significant difference between the use of a VDD-pacing lead and the time from first implantation (P = 0.28).

Conclusions: A VDD-pacing lead is an unsuccessful factor of lead extraction. When performing VDD-pacing lead extraction, an operator should pay special attention to the procedure.

Infectious myocarditis (IM) and infective endocarditis (IE), sometimes associated with infection of the surrounding mediastinal tissue or embolic complications caused by residual implantable cardioverter defibrillator (ICD) lead material embedded in the ventricle, present a significant challenge for cardiac surgeons due to the difficulty of precisely locating the old intracardiac pacing lead remnants because of the heart's continuous movement. We present the case of successful two-stage elective sternotomy extraction of two residual defibrillator leads, one trapped in the left innominate vein, easily removed after veinotomy without cardiopulmonary bypass (CPB), and the other embedded intramyocardially in the inferior wall of the right ventricle, successfully removed under CPB after fluoroscopic guidance. The patient was discharged four weeks post-operation without complications.

Background: Removal of cardiac implantable electronic devices (CIEDs) is strongly recommended for CIED-related infections, and leadless pacemakers (LPs) are increasingly used for reimplantation. However, the optimal timing and safety of LP implantation after CIED removal for infection remains unclear.This systematic review and meta-analysis aimed to assess complication rates (all-cause mortality and reinfection) when LP implantation was performed simultaneously with or after CIED removal.

Background: Pilonidal sinus disease (PSD) is a chronic debilitating condition predominantly affecting young men. Laser hair depilation is an established adjunct to surgical treatment for PSD and can lead to reduced rates of recurrence, and post-surgical interventions.This study aimed to assess the outcome of laser hair depilation therapy on disease progression in pilonidal sinus disease patients at the Birmingham Skin Regional Laser Centre.

An increasing amount of water pollution is being caused by an increase in industrial activity. Recently, a wide range of methods, including extraction, chemical coagulation, membrane separation, chemical precipitation, adsorption, and ion exchange, have been used to remove heavy metals from aqueous solutions. The adsorption technique is believed to be the most highly effective method for eliminating heavy metals from wastewater among all of them.

Background: Mouth breathing is related to morphological and functional alterations in growing individuals. Understanding early events that can lead to these changes can prevent or decrease the need for orthodontic treatment.

Objective: The goal was to assess the prognosis for dental alterations evidenced by changes in the incisor inclination and arch width after surgical intervention to normalize the mode of breathing in growing patients.
