Amiodarone (Cordarone) is an iodinated cardiac antiarrhythmic drug that causes a slate-gray discoloration of the sun-exposed skin and a yellow-brown stippling of the cornea. Histopathologically, biopsy specimens of aminodarone pigmentation sites disclose yellow-brown refractile granules in the reticular dermis. These granules were characterized by transmission electron microscopy as being concentrically arranged intralysosomal inclusions ("myelinlike" bodies) in dermal endothelial cells and perivascular smooth-muscle cells. Electron probe x-ray analysis of these same inclusions disclosed definite peaks for iodine, evidence for the presence of amiodarone or a metabolite of the drug at these sites. Amiodarone, then, concentrates in lysosomes and causes an accumulation of lipids similar to what has been seen with other cationic amphiphilic compounds, such as the glycosphingolipid stored in Fabry's disease. Amiodarone must be recognized as a cause of a drug-induced lipid storage disease with cutaneous and corneal manifestations.

Objective: In the present study, we aimed to compare in-hospital mortality and safety of intravenous beta-blockers and amiodarone in septic patients with new-onset atrial fibrillation (NOAF). The null hypothesis is that there is no significant difference in in-hospital mortality and safety of Beta-blocker (BBs) and amiodarone in treating NOAF in patients with sepsis.
Design: We conducted a retrospective analysis based on the MIMIC-IV database.

Health Care Resource Utilization With Dronedarone Versus Sotalol Following Catheter Ablation in Adults With Atrial Fibrillation.

Department of Medicine, Creighton University School of Medicine and CHI Health, Omaha, Nebraska, USA.
Background: Clinical trials support dronedarone use for atrial fibrillation (AF) following catheter ablation (CA); however, comparative data on health care resource utilization (HCRU) with other antiarrhythmic drugs are lacking.
Methods: Retrospective analysis of Merative MarketScan databases (January 01, 2012-March 31, 2020) comparatively assessed HCRU in US adults with AF who received dronedarone or sotalol post-CA. Patients with ≥ 12-months' pre-CA data were followed from post-CA index treatment to disenrollment, death, or study end.
Impact of Preventive Intravenous Amiodarone on Reperfusion Ventricular Fibrillation in Patients With Left Ventricular Hypertrophy Undergoing Open-Heart Surgery: Randomized Controlled Clinical Trial.

Background: Ventricular fibrillation (VF) is a vicious arrhythmia usually generated after removal of the aortic cross-clamp (ACC) in patients undergoing open-heart surgery, which could damage cardiomyocytes, especially in patients with left ventricular hypertrophy (LVH). Amiodarone has the prominent properties of converting VF and restoring sinus rhythm. However, few studies concentrated on the effect of amiodarone before ACC release on reducing VF in patients with LVH.

Monopolar electrocautery is usually a safe and effective technique used in laparoscopic cholecystectomy and bile duct surgery, but it may lead to adverse consequences, even ventricular fibrillation (VF). Amiodarone is an effective antiarrhythmic drug commonly used in practice to treat ventricular and atrial arrhythmias, but it may induce tachyarrhythmia or even VF. We report a case of VF occurring twice during cholecystectomy.
