Multiple shocks from ICDs can burn subcutaneous tissue: Case report

A new report published in Heart Rhythm Case Reports shows that Multiple shocks from implanted cardioverter defibrillators (ICDs) can result in subcutaneous tissue burns, as revealed by PET imaging for the first time.

Since clinical trials revealed that implanted cardioverter defibrillators lower mortality in a subset of individuals with cardiac disease, their usage has rapidly grown. The benefit of these devices is that they can treat malignant ventricular arrhythmias with high-energy shocks and anti-tachycardia pacing to lessen sudden cardiac death (SCD). Here, Christopher Perez and colleagues discussed the case of a 22-year-old man who suffered thermal harm from the ICD as a result of frequent defibrillations.

A 22-year-old guy was brought to the hospital for several acceptable ICD shocks after a history of myocarditis, ventricular fibrillation, and past out-of-hospital cardiac arrest status following single chamber ICD implantation. His medical background was significant for unknown gene alterations such as KCNH2, PKP2, and TTN. Prior to this stay, he claimed good health, frequent exercise, and no ICD discharge since placement. He admitted to not taking sotalol. The patient claimed hard exercise before to receiving fifteen shocks. The physical examination revealed discomfort and visible swelling at the location of the implantation, but no temperature. Interrogation of the device indicated monomorphic ventricular tachycardia at 300 beats per minute. Troponin levels began at 0.39 ng/mL (0.0-0.9 ng/mL) and peaked at 20.98 ng/mL.
