Abstract

Despite undisputable benefits conventional pacemaker therapy is associated with some specific complications due to the subcutaneous pacemaker placement and the transvenous leads. Recently 2 miniaturized leadless pacemakers, Nanostim (St. Jude Medical) and Micra (Medtronic), that can be fully implanted into the right ventricle using steerable delivery systems entered clinical application. These systems may – additionally to the cosmetic aspects – overcome the problems of conventional pacing. Initial clinical data for the Nanostim system indicate appropriate safety profile and performance. However it is still not completely known, which new complications may arise specific to the new technology, implantation and explantation. Large studies are underway to answer these questions.
