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.
