Total or Sub-Total Correction of a Marked and Long-standing Cardiac Dysrhythmia after Sofosbuvir/Ledispavir Treatment

Abstract

Cardiac dysrhythmias (atrial and/or ventricular fibrillation) represent a major medical problem, with possibly life-threatening complications, necessitating costly, life-long treatments or complicated procedures. We report here a case of a sustained correction of a severe and long-standing atrial dysrhythmia (hyperexcitability) and at a lesser degree, a ventricular hyperexcitability, occurring after treatment with a combination of sofosbuvir plus ledispavir administered to treat a chronic Hepatitis C virus infection (HCV). The correction appeared within the first days of anti-HCV treatment and was totally maintained 3 months after drug cessation and still noticeable 3 more months. The mechanism of such an antiarrhythmic action has still to be elucidated. If confirmed, the potential antiarrhythmic effect of sofosbuvir combined with another antiviral drug, could represent a real advance in atrial and maybe ventricular hyperexcitability treatment.
