Introduction:

RENEDI (“Registro Nacional de Extracción de Dispositivos”) is the first inter-societary, observational and prospective registry on lead extraction designed in Argentina.

Objective:

To allow the observation of the implementation of this type of intervention in our country.

Materials and method:

an online database platform was designed. Data were supervised 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, 176 implantable cardioverter-defibrillator leads and 71 cardiac resynchronization therapy defibrillators; 233 atrial, 367 ventricular and 21 coronary sinus leads placement. The average lead dwell time was 105.9 months. The commonest indication for removal was infection (68% - local 71%). Vascular or cardiovascular surgeons were usually the primary operator (81%). The presence of stand-by was reported in 72% of cases. Percutaneous approach (98%) was predominant. Minithoracotomy/sternotomy was performed in only 7 patients (16 leads). A total of 158 (25%) leads with a median dwell time of 33.3 months were extracted using simple traction. Additional tools were used in 75% of cases. Overall complications rate was 4%. Only one major complication was reported. Minor complications occurred in 3.6% of procedures. Complete procedural success was 96.2%. No deaths were reported.

Conclusions:

Argentinian practice has demonstrated that transvenous lead extraction 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.
