The thinning of the skin over the pocket is an occasional phenomenon in patients with cardiac implantable electronic devices (CIEDs) most often associated with the technique of implantation of the device. It is likely that the thinning of the skin over the generator is a risk factor for the development of infectious complications in patients with CIED. Analysis of large database of 3706 patients undergoing transvenous lead extraction (TLE) showed higher number of points of PADIT score and more often previous pocket plastic surgery in patients with too shallow pocket. Most likely, diagnosing only a too shallow CIED pocket is often an early symptom of infection.
