RENEDI: Results of the first observational and prospective registry of
transvenous lead extraction in Argentina. Inter-societary Working Group.
Abstract
Background and aim: RENEDI (“Registro Nacional de Extracción de
Dispositivos”) is the first registry on Transvenous Lead Extraction
(TLE) designed in Argentina with the objective of providing data on lead
extraction real-world practice. Methods: An online database platform was
designed. Data referred to patients, leads and extraction procedures
were compiled and reviewed by a Committee. Results: A total of 621 leads
were extracted from 325 patients (average age of 59 years; 71% male).
The targeted leads included 374 pacemaker leads (61%), 176 implantable
cardioverter-defibrillator leads (28%) and 71 cardiac resynchronization
therapy devices (11%). Two hundred and thirty-three (38%) atrial, 367
(59%) ventricular and 21 (3%) coronary sinus leads placement. The
average lead dwell time was 105. 9 months. The commonest indication for
removal was infection (68%-Local 71%). Cardiovascular surgeons were
usually the primary operator (81%). The presence of cardiovascular
stand-by was reported in 72% of cases. Percutaneous approach (98%) was
predominant. A total of 158 (25%) leads with a median dwell time of
33.3 months were extracted using simple traction. Overall complication
rate was 4%. Only one major complication and no deaths were informed.
Minor complications occurred in 3.6% of procedures. Complete procedural
success was 96.2%. Incomplete extraction was obtained in 23 leads. No
permanent disabling complications or procedure-related deaths were
reported. Conclusions: Current Argentinian practice has demonstrated
that TLE is a safe and effective procedure associated with a low
incidence of complications and high success rate when it is performed in
well-trained hands.
