Life Threatening

Ventricular arrhythmia is a violation of the frequency, rhythm, sequence of propagation of excitation and myocardial contraction caused by the source of impulses, which is localized below the His band: in the branches of the His band, in the Purkinje fibers or directly in the muscle thickness of the ventricles of the heart (ectopic focus of excitation). Its diagnosis is quite complex, and the consequences can be life-threatening. Treatment requires the rapid use of effective antiarrhythmic drugs.

Ventricular arrhythmia storm is a state of cardiac instability characterized by multiple ventricular arrhythmias or multiple ICD therapies within a 24-hour duration. Management of this life-threatening state depends on the reversal of the cause besides either electrical or medical management of the arrhythmia. We report a case of a 54-year-old male who underwent a percutaneous coronary intervention following massive acute myocardial infarction. Afterwards, he developed frequent life-threatening ventricular arrhythmias that required multiple shocks and antiarrhythmic medications. Despite all these interventions, it was very difficult to control the electrical instability, but after overdrive ventricular pacing, the storm subsided and within a few days the case was stabilized. Overdrive pacing is an easy temporary modality to control the resistant arrhythmia following myocardial infarction.

Cardiac Sympathetic Denervation

Ventricular arrhythmias are potentially life-threatening disorders that are commonly treated with medications, catheter ablation and implantable cardioverter defibrillator (ICD). Adult patients who continue to be symptomatic, with frequent ventricular arrhythmia cardiac events or defibrillation from ICD despite medical treatment, are a challenging subgroup to manage. Surgical cardiac sympathetic denervation has emerged as a possible treatment option for people refractory to less invasive medical options. Recent treatment guidelines have recommended cardiac sympathectomy for ventricular tachycardia (VT) or VT/fibrillation storm refractory to antiarrhythmic medications, long QT syndrome, and catecholaminergic polymorphic VT, with much of the data pertaining to pediatric literature. However, for the adult population, the disease indications, complications, and risks of cardiac sympathectomy are less understood, as are the most effective surgical cardiac denervation techniques for this patient demographic. This systematic review navigates available literature evaluating surgical denervation disease state indications, techniques, and sympathectomy risks for medically refractory ventricular arrhythmia in the adult patient population.

Abstract BACKGROUND AND OBJECTIVES: The regular clinical follow-up of the patient with the implantable cardioverter-defibrillator (ICD) device was seriously affected by the COVID-19 outbreak. Due to the high risk of contamination, patients didn’t admit to the clinics for the ICD device control. It has been observed that arrhythmic events increased during the COVID-19 outbreak. In this study, we aimed to investigate the frequency of severe ventricular arrhythmias and ICD device therapy in COVID-19 patients with ICD.METHODS: In this single center-observational study, we assessed severe ventricular arrhytmias and ICD therapies by analyzing recorded data of 33 patients (24 males, 72.7%) 3 months before and after getting COVID-19 during the COVID-19 pandemic in Van, Turkey, between 15 August 2020 and 15 January 2021. RESULTS: Before the diagnosis of COVID-19, 6 ventricular tachycardias and 1 ventricular fibrillation were observed. When we analyzed the records after the diagnosis COVID-19, 17 ventricular tachycardia and 3 ventricular fibrillation episodes were observed. Considering the the ICD device therapies, 5 of these severe tachyarrhythmias were terminated by antitachycardia pacing (ATP) and 2 with shock therapy before the diagnosis of COVID-19. After the COVID-19, 14 of them were terminated by ATP and 6 of them ere terminated by shock therapy.CONCLUSION: The effects of the COVID-19 pandemic, especially on ventricular arrhythmia, have not been reported sufficiently. In our study, it was observed that life-threatening ventricular arrhythmias and the ICD therapies were increased in patients with COVID-19, especially in the first month after the diagnosis COVID-19.

Supraventricular Tachyarrhythmias

Amiodarone is one of the most frequently used antiarrhythmic drugs on the market, treating both life-threatening ventricular arrhythmias as well as supraventricular tachyarrhythmias. Some of its most commonly known side effects include corneal deposits, cardiac toxicity, pneumonitis, thyroid hormone fluctuation, and dermatological reactions. Despite the frequency of occurrence of neurological complications secondary to Amiodarone they remain to be under-recognized by healthcare professionals. This casereport aims to increase awareness of the neurological complications of Amiodarone.

Underlying Mechanisms

Atrial fibrillation (AF) is the most common arrhythmia and is associated with substantial cardiovascular morbidity and mortality, with stroke being the most critical complication. Present drugs used for the therapy of AF (antiarrhythmics and anticoagulants) have major limitations, including incomplete efficacy, risks of life-threatening proarrhythmic events and bleeding complications. Non-pharmacological ablation procedures are efficient and apparently safe, but the very large size of the patient population allows ablation treatment of only a small number of patients. These limitations largely result from limited knowledge about the underlying mechanisms of AF and there is a hope that a better understanding of the molecular basis of AF may lead to the discovery of safer and more effective therapeutic targets. This article reviews the current knowledge about AF-related ion-channel remodelling and discusses how these alterations might affect the efficacy of antiarrhythmic drugs.

Surveillance Analysis

A recent surveillance analysis indicates that cardiac arrest/death occurs in ≈1:50,000 professional or semi-professional athletes, and the most common cause is attributable to life-threatening ventricular arrhythmias (VAs). It is critically important to diagnose any inherited/acquired cardiac disease, including coronary artery disease, since it frequently represents the arrhythmogenic substrate in a substantial part of the athletes presenting with major VAs. New insights indicate that athletes develop a specific electro-anatomical remodeling, with peculiar anatomic distribution and VAs patterns. However, because of the scarcity of clinical data concerning the natural history of VAs in sports performers, there are no dedicated recommendations for VA ablation. The treatment remains at the mercy of several individual factors, including the type of VA, the athlete’s age, and the operator’s expertise. With the present review, we aimed to illustrate the prevalence, electrocardiographic (ECG) features, and imaging correlations of the most common VAs in athletes, focusing on etiology, outcomes, and sports eligibility after catheter ablation.
