Background
• In recent years the number of CIED complications increased because of:
Increase of device implantation per year More complex procedures Sicker and high risk patients
• Transvenous Lead Extraction is the gold standard in the treatment of CIED-related infective complications and is often required in the management of lead malfunction
• TLE is unexplored across European countries regarding appropriate indications, tools, techniques, success rate and complications in acute and long-term follow-up
EURObservational Research Programme
3ELECTRa Registry Status Report – ESC CONGRESS, Barcelona, Spain - 31 August 2014
ELECTRa: Objectives
• Primary objective: To evaluate the acute and long-term safety of TLE
• Secondary objectives: To describe characteristics of patients and leads undergoing TLE
procedure
To evaluate indications, tools and techniques for TLE procedures
To assess the acute and chronic outcomes of TLE procedures
To compare outcomes between low and high volume centers
The ELECTRa (European Lead Extraction ConTRolled) Registry is a prospective, multicentre registry of patients undergoing Transvenous Lead Extraction in ESC countries

ELECTRa: Study design
• Recruitment of patients started on November 2012 and ended on May 2014
• All consecutive patients with indications for TLE (following HRS consensus document) in the participating centres during the enrolment period were included
• Data were collected using a web based system and audited at randomly selected centres
• No specific protocol for the procedure, materials, techniques of extraction, or treatment after the procedure was mandatory during this observational study
• High and low volume centres were defined on the basis of their volume of activity at the end of the study calculating the median number of patients enrolled/month/centre

ELECTRa Outcomes:Major complications
Major complication: Any of the outcomes related to the procedure which is life threatening or results in death. In addition, any unexpected event that causes persistent or significant disability or any event that requires significant surgical intervention.
1. Death
2. Cardiac avulsion or tear requiring thoracotomy, pericardiocentesis, chest tube or surgical repair
3. Vascular avulsion or tear requiring thoracotomy, pericardiocentesis, chest tube or surgical repair
4. Pulmonary embolism requiring surgical intervention
5. Respiratory arrest or anesthesia related complication leading to prolongation of hospitalization
6. Stroke
7. Pacing system related infection of a previously non-infected site

ELECTRa Outcomes:Major complications
High Volume Centre > 2.5 pts/month
Low volume Centre ≤ 2.5 pts/month
Intra-procedural complications: Any event related to the performance of a procedure that occurs or becomes evident from the time the patient enters the operating room until the time the patient leaves the operating room. Post-procedural: Any event related to the procedure that occurs or becomes evident pre-discharge.

ELECTRa Outcomes:Minor complications
Minor complication: Any undesired event related to the procedure that requires medical intervention or minor procedural intervention to remedy, and does not limit persistently or significantly the patient’s function, nor threaten life or cause death.
1. Pericardial effusion non requiring pericardiocentesis or surgical intervention
2. Hemothorax not requiring a chest tube
3. Hematoma at the surgical site requiring reoperation for drainage
4. Arm swelling or thrombosis of implant vein resulting in medical intervention
5. Vascular repair near the implant site or venous entry site
6. Hemodynamically significant air embolism
7. Migrated lead fragment without sequelae
8. Blood transfusion related to blood loss during surgery

ELECTRa Outcomes: Radiological Success rate
Radiological Success Removal of all targeted leads and all lead material from the vascular space, with the absence of any permanently disabling complication or procedure related death. Partial = less than 4 cm remains in the cardiovascular system
(Wilkoff BL et al. Heart Rhythm 2009;6:1085–104)

18ELECTRa Registry Status Report – ESC CONGRESS, Barcelona, Spain - 31 August 2014
Clinical success Based on the achievement of clinical outcome according to intention to treat defined as “removal of all targeted leads and lead material from the vascular space, or retention of a small portion of the lead that does not negatively impact the outcome goals of the procedure.

Conclusions
• ELECTRA Registry is the first large prospectic registry on Transvenous Lead Extraction conducted in the ESC countries
• Infective and non infective indications are almost equally considered in clinical practice for this kind of intervention
• The radiological success rate is more than 95% and the assumed clinical success rate is extremely high (98,3%)
• Major and Minor complications are more frequent in low volume centers and mainly in the post-operative period
• An accurate analysis of all data collected will give us details about the real world on TLE and will make possible a better knowledge to further improve the outcomes
