In a prospective Dutch cohort of 1,517 patients, 4 early complications were 9.2% and tended to a decrease after the first 6 months of implantation; the main ones, in order of frequency, were related to the cable in 5.54% (3.34% of dislodgement), device pocket (4.75%, excluding infection), hematoma 2.9%, local trauma (2.77% – with pneumothorax being 2.24%) and pocket infection (0.64%). In the late period, cable complications remained the same and pocket-related complications decreased, especially regarding the infection 495
