Introduction
The MTPS is an expanding technology that has been proved to be safe and
effective both in investigational studies and real world setting. MTPS
has been developed to address the limitations of standard transvenous
leads-based pacing, by virtually eliminating lead - and pocket-related
complications.
As a consequence, the population that should be expected to benefit the
most from a leadless pacemaker (LP) is that with a higher risk of device
infection. In addition, LP may offer a significant advantage over
traditional leads based pacing in case of severe venous obstruction of
subclavian veins/superior vena cava preventing pacing lead
insertion1,2. Anyway, facing these pathological
conditions may open an unexplored and challenging operative scenario. We
report on a patient requiring pacemaker implantation, due to third
degree atrioventricular block, and with a paraneoplastic chronic
thrombosis of the superior vena cava infiltrating the right atrium and
precluding the implantation of a traditional pacemaker.
