Abstract
A 70-year-old man affected by a metastatic lung adenocarcinoma developed
an atrioventricular block. Due to an extensive thrombosis of the
superior vena cava with invasion of the right atrium, a traditional
transvenous pacemaker system (TTPS) implantation was not feasible.
Despite the extensive development of the thrombosis in the right atrium,
the patient successfully underwent Micra transcatheter pacing system
(MTPS) implantation. This case report describes a quite rare condition
in which a leadless pacemaker (LP) is the best option to treat an
atrioventricular block and where the recent introduction of the
groundbreaking AV MTPS would be the optimal therapy.
