Marcapasos sin cables: un reto futurista en estimulación intracardiaca.

Introduction: Leadless pacemakers have revolutionized the pacing field by reducing their size and making them completely intracardiac, thus reducing complications related to pockets and transvenous leads. In this article, we review the available data on leadless pacemakers and present a series of the first 9 patients implanted in our country. Objective: To present a series of 9 cases implanted in our country so far (April 2022) and describe the clinical characteristics of these patients. Materials and method: A descriptive study, case series presentation. Results: 9 devices were implanted in various institutions in the country; the average age of the patients was 72 years, and 77% were men, with a history of previous pacemaker implantation in up to 89% (75% due to complete AV block). The main indication for device implantation was recurrent infections (66.7%). No immediate complications occurred in any of the cases. Conclusions: Although the indications for leadless pacing, there is solid evidence of its feasibility, safety and efficacy both in the short and medium term as an alternative in selected patients. We consider that leadless pacemaker implantation in our country has been a successful experience. [ABSTRACT FROM AUTHOR]
