Abstract

NINO, César D. et al. Extraction of intracardiac electrode located in the posterior interventricular vein, with a mechanical rotational cutting sheath, in a patient with persistent left superior vena cava. Rev. Colomb. Cardiol. [online]. 2024, vol.31, n.3, pp.174-178.  Epub July 29, 2024. ISSN 0120-5633.  https://doi.org/10.24875/rccar.21000072.

The use of cardiac electronic devices has increased over the last decades, which has generated an increase in the number of electrode extraction procedures, as a greater number of patients with multiple comorbidities undergo cardiac electronic device implantation. Currently, the percutaneous technique is preferable in most patients, given its excellent clinical results and lower morbidity and mortality compared to surgical extraction. Nonetheless, some clinical scenarios increase procedural difficulty, including anatomical variants, or the need to extract passive fixation leads. We present a case of a patient with pacemaker due to complete atrioventricular block, with diaphragmatic stimulation caused by a passive fixation ventricular electrode that was implanted in a posterolateral vein of the coronary sinus through a persistent left superior vena cava, who underwent successful transvenous lead extraction.
