Strategies for the Long-Term Preservation of Site for Future Implantation of Cardiac Implantable Electronic Devices (CIEDs): Two Decades of Experience.

Abstract

IntroductionImplantation of cardiac implantable electronic devices (CIEDs) is an art of science. As the volume of implantation has increased worldwide, so has the rate of complications. Infection, fibrosis, lead and device erosion, lead displacement, right ventricle perforation, lead fracture, and insulation break are the common complications in the implantation process. This exposes the patient for reopening and threatens the implantation for further complication due to infection, fibrosis of veins, failure to retrieve the implanted wire, and failure to re-implant the device on the same site. We slightly changed our implantation technique to preserve the implantation site for future implantation and reduce the rate of complication in the index implantation.MethodsThis randomized control trial was conducted from January 2016 to September 2019 at Hayatabad Medical Complex Peshawar, Pakistan. A consecutive sampling technique was used to obtain a sample size of 602 patients keeping a 95% confidence interval and a 5% margin error. We adopted a strategy to take prick, for implantation of devices, inside the pocket, which reduces the number of sutures, hastens the procedure, prevents erosion, and minimizes the chance of subclavian crush syndrome and insulation break. We also selected the minimum possible length of leads. This will possibly decrease the chances of cumbersome fibrosis around the lead and device and will make future implantation convenient.ResultsThere was a total of 602 procedures in the study period. About 253 (42%) procedures were done in the newly adopted strategy and 349 (58%) were performed in the conventional way. Our complication rate grossly reduces in the novel way of implantation in which we took our prick inside the pocket.ConclusionA slight modification in the implantation of CIEDs not only prevents the rate of complication in the index implantation but will also possibly preserve the site for future implantation.
