“Life-saving” inappropriate implantable cardioverter-defibrillator shocks in a cancer patient
Journal Title: OncoReview - Year 2016, Vol 6, Issue 3
Abstract
Impaired left ventricular ejection fraction (LV EF) in patients with cancer can disqualify them from targeted antineoplastic treatment. We present the case of 63-year-old male with gastric cancer treated palliatively, with concomitant dilated cardiomyopathy, atrial fibrillation (AF) and after implantation of a cardioverter defibrillator (ICD), in whom inappropriate ICD discharges caused unexpected return of sinus rhythm and significant LV EF improvement, what subsequently led to reclassification to targeted chemotherapy. In conclusion, unexpected return of sinus rhythm in cancer patients with AF and reduced LV EF may lead to LV EF recovery and enable the use of antineoplastic treatment with improved prognosis.
