The most common complication of a defibrillator is infection at the implant site.
While other complications can occur following the implantation of an implantable cardioverter-defibrillator (ICD), such as swelling, bleeding or bruising, blood vessel damage, bleeding around the heart, and blood leaking through the heart valve where the ICD lead is placed, infection at the implant site is reported as the most frequently encountered issue. Proper sterile technique during implantation is crucial to minimize this risk.
